ABCD – Aluminium, Boron, Coating, Diamonds

Over the last decade, the demand for aluminium moulds has increased dramatically but consistently and apparently this shows no sign of slowing down, changing or ceasing all together.  Metal coatings are provided for a range of fabricated metal components, but the largest business currently is mould coating and plating.  Specifically the demand for aluminium itself is increasing.  This is because companies have begun to discover that that aluminium moulds can last longer, much longer, than what they were predicted.  The extra longevity of the aluminium moulds can be enhanced further if buyers opt for the mould to be plated with electroless nickel.  This is a cost effective way to extend the life of aluminium tooling and has become extremely popular with automotive suppliers.  Alternatives to aluminium coating or plating can be nickel boron plating and nickel diamond plating which are also popular but aluminium remains the optimum and is only set to continue growing in demand.

Nickel Boron Plating

Nickel boron is a surface deposit coating that can be applied to many different metals including stainless steel, aluminium and titanium.  It acts as a great alternative to chrome plating and has many benefits, which include extending wear and corrosion resistance.  The nodular structure of nickel boron reduces drag in aerodynamic and fluids in circumstances such as ship propellers, down-hole oil crude oil pumping equipment, automotive and truck transmissions and greaseless guns.

Nickel Diamond Plating

Nickel Diamond Plating is where electroless nickel deposits are combined with particles of diamonds.  Many substrates can be coated using this method such as carbon, aluminium, stainless steel and alloys.  Substrates, once coated in this, become extremely highly corrosion and wear resistant and therefore have a much increased lifespan.  Part maintenance and replacement costs are reduced dramatically, as are the costs for such.  This is a popular technique in industries such as textile industry, wood working tools, computer parts, paper handling equipment, automotive water pumps, chemical process pumps and gage blocks.nickel-diamond-plating-nitec

Electroplating and Electroless Plating – Less is More!

less-is-more-electroless-nickel-plating

The success of many products, which a lot of us are probably unaware of, are dependent on the application of surface engineering.  Such a huge amount of products, both commercial and industrial, are needy of it.  These include aeroplanes, computers, cars, trains, buildings, medical implants, mobile phones, and electronic devices – what would you do for a week without having just the products that have been listed?

The Electroplating Process

Electroplating is a process of surface engineering.   This is where metal coating is applied to a metallic or other conducting surface by and electrochemical process.  This process uses electric current in order to form a coherent coating on an electrode.  Electroplatings number one use is to change the surface properties of an object, such as the wear resistance, lubricity, corrosion protection and abrasion, for example.  It also builds up the thickness on objects, too.

The Electroless Plating Process

Electroless plating is a high quality, cost effective and eco-friendly solution to coating metals like stainless steel, as it can dramatically enhance the life expectancy.   The main difference between electroplating and electroless plating (yes, is in the name!) is that no electricity is used in the process of electroLESS plating.  Electroplating baths are used and are closely monitored as the parts must have a constant power supply directly provided to them in order for the ion attraction to be initiated in the bath contained solution on to the metallic surface of the submerged object.  This is when the chemical reaction occurs as the ions are being reduced and oxidised.

What does Plating help with?

  • Creates adhesion
  • Creates even coverage
  • Can add thickness to plated object
  • Weep holes can be added for drainage
  • Plating can carried out on many types of metal including electroless nickel plating
  • Conductor
  • Has low friction
  • Adds strength
  • Corrosion resistant
  • Makes objects hard wearing

Choose the Right Coating to Maximise Product Optimisation in the Automotive World

The idea of a specialised coating is for the surface of metals to be permanently enhanced by them.  This can be used on other substrates as well and on many components and equipment, too.  These specialised coatings, in effect, act as a deterrent and solve wear, corrosion, lubricant and release problems.   But to choose the best coating for you, the most important things which must be taken in to consideration is the operating environment.

Put a Coat on!

Surface coating usage has grown enormously in the automotive industry over the last fifty years.  Initially, the internal combustion engine was usually manufactured from cast iron, forged steels and die-cast aluminium alloysHeat treatment provided the wear surface for these elements along with white metal or bronze bearings.  They were oiled and lubricated to allowance clearance between moving surfaces.  Half a century later, this method is still used today, though we need and expect more out of our cars.  We expect them to last longer, drive considerably more substantial distances and we need them to abide by our emissions regulations now, too – no mean feat!  In case that wasn’t enough, we expect our cars to do all of this with less fuel and lighter engines which have a lower tolerance to engineering and lower friction between their moving parts.  Due to this, a wider range of materials and coating variety have been required by us all, so that the wear, corrosion and friction problems and expectations could be overcome.

Automotive Parts and Protective Coatings

Piston rings, skirts and pins are coated frequently by hard-wearing, low friction coatings.  This is to hengine-block-nitecelp the initial running-in and advocates long-life performance.  It also helps with lower oil lubrication levels which are commonly associated with cold engine starts and reduces the amount of lubricant allowed to enter the combustion chamber.  Ceramic coatings provide the thermal insulation of piston crowns, usually in diesel engines, where increased and high temperature thermal spray or vacuum use methods are often practiced.

Mating cylinder linings can be coated with electrolytic or electroless plated composite finished which incorporate hard particles of silicon carbide, diamond or boron nitride.  The engines design and performance influence are what enable the design engineer to make the coating choice.

Bio fuels have caused a large amount of corrosive issues with the fuel input systems, fuel storage and fuel delivery systems.  There are a great array of thin coatings which can be applied to these areas in order to prevent corrosion from occurring such as electroless nickel plating which is often enhanced with the use of powder coating or e-coat top coats.

The 3 P’s – Plating, Process and Products

After only a couple of decades, the metal finishing world has been transformedElectroplating is the most modern form of metal finishing which is used in a wide array of industries such as aerospace, automotive, healthcare and military defence, to name but a few.  During this electrochemical process the metal ions in solution are bonded to a metal substrate via the process of electrodeposition.

Pre-Electroplatingletter-p

Before electroplating was a front runner in the metal finishing world, parts had to be properly cleaned before entering a series of chemical baths to prepare and activate in order to prepare and activate the metal to create strong adhesion created during the process of electrodeposition.

The Plating Process

Electroplating baths involve multiple variables and components which must be closely monitored constantly.  The parts have a constant power supply provided directly to them which initiates the ion attraction in the solution towards to metallic surface.  Every time a mole of electrons is transferred to the part in question, one mole of metallic ions in solution adhere directly to the part as well.  Whilst this happens a chemical reaction also occurs on the surface of the part which includes ions being reduced and oxidised.

What do you need to consider before electing to use Electroplating?

  • Because electrical and chemical reactions are both involved in the electroplating process, exposure is critical to the finished product. The nesting of parts will create a lack of adhesion and lack of coverage which should be avoided.
  • Plating thickness should be kept in mind when dimension tolerance is designated and the extra room for electroplating should be left so that parts fit together after the process has occurred.
  • What environment are the parts going to be exposed to? This will help you to decide what level of thickness you will require in order for your part to be made corrosion proof.
  • The geometry of the part in relation to the current distribution aka current density, across the surface of a part. Plating builds up on sharp corners, bends and threads for example.
  • Do you need to think about the drainage of plating solutions the addition of a weep hole may need to be added during its design phase in order for it to be successful.
  • Think about the type of metal you should be using in relating to the job you want it to do for you! What characteristics do you need the surface to have for the job in question?  Does it need to be a conductor, have low friction, be strong, corrosion resistant, hard wearing etc?  This should make you therefore lead you in to thinking about the types of plating which would be effective – Gold plating, Silver plating, Nickel plating or Copper plating
