Why Choose Electroplating?

copper-electroplating-nitecElectroplating is a modern form of metal finishing.  It is commonly used in the automotive, aerospace, medical, army and electrical industries.  It occurs by means of an electrochemical process when metal ions in an electrolyte solution bond to a metal substrate through electrodeposition.   The required metal component is suspended in solution, whereby a direct power supply provides a direct flow of current to the said metal component in the chemical bath.  This current provokes the ions in the solution to attract to the surface of the metallic part, resulting in a metal coating which covers the base metal thoroughly.

Electroplating Benefits

Electroplating is mainly done in order to enhance the performance and longevity of the component part in question.  Certain characteristics can be added to the part in order to create specific needs for the manufacturers.  These can include areas such as:

  • Lower friction through greater lubrication
  • Better wear, abrasion and corrosion resistance
  • Temperature and impact resistance
  • Improved conductivity
  • Improved solderability
  • Porosity reducing
  • Creating added strength and hardness to the component
  • Creating a thicker appearance to smaller or undersized components
  • Increased protection for EMI and RFI shielding

Common Plating

Plating facilities match base metals with a wide array of coating surface metal finishes.  The most commonly used in this field are copper, brass, nickel, steel and bronze.  In order to decide which surface metal is used to coat for the finish, the components uses are highly considered so that the manufacturer can get the highest performance and longest lasting component part electroplated.

As examples:

Gold plating is the perfect solution for electrical conductivity, heat protection and corrosion and can survive in a multitude of environments and temperatures.

Silver plating is commonly used in the electrical industry dues to its low electrical resistance.

Nickel plating is ideal for the chemical industry.  It protects against chemicals and is corrosion and wear resistant.

Copper plating is most commonly used in the automotive industry.

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.

Increase the Corrosion Resistance of Brake Calipers with Electroless Nickel Plating

As experts in the process of electroless nickel plating, NiTEC UK regularly plate arguably the most important part of a cars’ brake part; the brake calipers. High performance brake calipers are a key part of a modern car, and nickel is excellent for protecting steel, so is the perfect coating for applications of this sort.

As brake calipers are a necessity to allow your vehicle to stop, it is essential for them to be hard wearing and long lasting. Brake calipers are a vital part of your vehicle’s breaking system as they squeeze the brake pads against the surface of the brake rotor to slow or stop the vehicle.

Most cars on the road today have disk brakes. In a disc-braking system the car’s wheels are attached to metal discs, or rotors, that spin along with the wheels. The job of the brake calipers is to slow down the wheels of the car by creating friction with the rotors. It fits over the rotor like a clamp, and inside it is a pair of metal plates which have been bonded with friction material called brake pads.

Anti-Corrosion Coatings for High Performance Brake Calipers

nickel plated brake caliperNickel plating is the perfect solution to creating hard wearing, corrosion resistant brake calipers, and is a very effective way of coating and protecting steel.

Brake calipers are also exposed to difficult environments, for example heat, cold, summer, winter, snow and salt. Therefore, a corrosion resistant coating on these parts is very important to ensure the longevity of the cars braking system.
