Rising Base Metals Rocketing to the Top?

nickel-plating-plated-nitecBase metals are essential in the growth of the infrastructure, manufacturing and utilities sector of the UK.  The mining of base metals refers to major industrial non-ferrous metals like nickel, copper, tin and aluminium.  It is the dramatically increasing energy and urbanisation demand which are making the need for the metals rise, as well as the fact that they are used for automotive systems, metal coatings, electrical systems and make many goods more durable.  But will fluctuating prices negatively impact the base metal market?

 

Nickel Plating is Key

In 2014, Lead-zinc accounted for 24% of the global market and copper accounted for 16%.  Zinc was popular due to its specific characteristics, such as its unique bonding abilities with other metals, anti-corrosive properties and it has the ability to galvanise well.  The attributes have boosted its use considerably.  Copper is predicted to rise, forecast until 2023, thanks to its proven strength in the infrastructure sector.  The use of tin is also set to rise through the use of tin coating for electronic components in the automotive sector.  However, the most interesting sales increase seems to be a very specific area of the Nickel world to increase its sales – this seems to be nickel plating – though the reasons or sectors remain unspecified.

 

Information Regarding Nickel Plating

There are two types of Nickel Plating – Electroless Nickel Plating (ENP) and Diffused Nickel Plating.

Diffused Nickel Plating is a simple process which is the most effective nickel coating, ensuring a high resistance level against corrosion.  This is thanks to its total encapsulation plating method.  It has been proven that their corrosion resistance is more effective than that of the highest grade stainless steel, whilst at the same time being much cheaper.  Diffused Nickel Plating is the perfect plating method if your components are used in marine or salt environments.  This gives them a 30 year sub-sea guarantee.

In a similar way, Electroless Nickel Plating is a high quality but cost effective solution to metal coating which can extend the longevity of components dramatically.  It is creates a good resistance against corrosion and is often used in marine, oil and defence industries.    Electroless Nickel Plating prevents rust, wear and friction.  It can also be hardened through the use of heat treatment and is guaranteed not to chip or flake, like paint or varnish does.

Electroless Nickel Plating and Diffused Nickel Plating

A question often asked is…What is the different between the two types of Nickel Plating?  The basic answer is very simple – the plating processes used are very different.

It has already been deciphered that Diffused Nickel Plating occurs when the encapsulation plating method is performed but this is not the same as Electroless Nickel Plating.  The process for this occurs when a layer of even thickness metal is deposited evenly over the surface of a component, no matter what its shape.  The uniformity in its coating means that it is the perform plating method for components which are used in particular industries, such as Healthcare, Defence, Automotive and Aerospace, where the components are often not standard, need to be hygienic, regularly cleaned and are under constant stress.

Corrosion Resistant Coatings for Marine Environments

Rusty mining equipment

Mining equipment suffering from rust and corrosion

Corrosion can be a big problem for parts and machinery operating in marine environments. Mild steel is commonly used for marine applications due to its strength, ease of fabrication and relatively cheap price.

The only problem is, it corrodes very easily when exposed to seawater. So when mild steel isn’t protected by a corrosion resistant layer or barrier, it quickly loses its strength and can, therefore, result in failure of parts.

What is Corrosion?

Corrosion is the gradual destruction of materials by chemical reaction with their environment. It is the oxidisation of the metal at the interface between the metal and the environment, and the reaction results in the degradation of the mechanical properties of the metal. Corrosion is dependent on many factors, including oxygen concentration, pH, water temperature and the presence of dissolved salts such as chloride, sulphate and sulphites.

Pitting Corrosion

Pitting corrosion is a type of corrosion that occurs on mild steel in a localised fashion. The steel penetration can be very deep in relation to the area under attack, and it is therefore one of the most dangerous types of corrosion.

Bacterial Corrosion

Bacterial corrosion can also be referred to as micro-biological corrosion or anaerobic (without oxygen) corrosion. This type of corrosion is likely to happen if the environment that the metal is exposed to supports bacterial activity. For bacterial corrosion to occur, there must be stagnant water, a hydrocarbon food source e.g. oil or coatings, the presence of sulphates, an operating temperature of between 20 – 40C, and the presence of bacteria.

Corrosion Prevention Using Metal Coatings

The prevention of corrosion requires the elimination or suppression of the chemical reaction between the environment and the metal. One way of preventing this reaction is by applying a metal coating to the surface of the substrate, and the effectiveness of the coating depends on factors including the type of coating used, the operating environment and the coating type.

SeaTEC 100 Marine Corrosion Protection

Here at NiTEC, we have developed a corrosion resistant metal coating that effectively protects mild steel from salt spray corrosion and marine corrosion for an extensive period of time.

Nickel Use in Rocket Engines and Aerospace

Nickel coatings are often used in the aerospace and aircraft industry because they are an effective corrosion resistant coating at high temperatures.

This means that they are capable of protecting airfoil components from abrasion and erosion by providing a surface coating that will allow high nickel/chromium alloy parts to be joined by brazing or welding, to produce nickel or nickel alloy components for space applications and to repair worn or damaged components.

By repairing parts rather than replacing them, they can continue to be used rather that scrapped.

Nickel and alloys of nickel are often used for space applications.

Electroless nickel coatings are used in the Aerospace industry for space applications:

  • Docking
  • Cargo bays
  • Rudder mechanisms of the NASA Space Shuttle

Nickel electroforming has also been used in the space program. It has been used to produce lightweight precision parts for rocket engines, such as:

  • Waveguides
  • Antennae
  • Bellows
  • Heat shields
  • Thrust chambers

High precision electroformed nickel bellows are widely used in the aerospace industry, as electroforming is often the only practical and most economical method. These parts are used for:

  • Flexible electromagnetic interference shielding
  • Metallic hermetic seals
  • Volume compensators
  • Temperature and pressure sensors
  • Flexible couplings

Nickel Plating Services in the Automotive Industry

Electroformed, electroplated and electroless nickel is commonly used in the automotive industry.

One of the biggest and most obvious uses of nickel is the use on bumpers, wheels and grilles. The use of nickel plating on parts such as these is partly due to the fact that it looks good with its shine and bright finish. But nickel also provides excellent corrosion resistance, durability and wear resistance, as is often demanded by makers of vehicles.

Nickel and Industry Warranties

Nickel plating is a great way of metal hardening and can protect components for decades, which is obviously great news for the automotive industry because it means that manufacturers can offer industry warranties.  High quality plated components can be produced in bulk, with consistency and reliability.

The automotive industry is the biggest user of nickel for plating applications. Steel bumpers are very popular as they look great, and they are also very durable. Substrate materials include steel, aluminium and plastic. The benefit of using nickel plating on substrates such as these is that they are relatively cheap, and with a layer of nickel plating they can be made extremely durable.

Environmental Benefits of Nickel

Nickel plating lightweight materials such as aluminium and plastic is also beneficial because lightweight parts on a vehicle improve fuel efficiency. It’s also better for the environment for parts to have a longer life as it reduces scrap. Also, plated components can be recycled, which is good for the European auto industry as their objective is to produce vehicles that are completely recyclable.
