What You Need to Know about Hard Chrome Plating

What is hard chrome plating?

Hard chrome plating is an electrolytic process in which chromium is deposited onto a metal substrate to give it enhancing properties for durability, wear and hardness. The electrolytic process will typically be achieved by passing an electric current through a chromic acid solution – an electrolyte bath, between two electrodes. One of these electrodes will act as the substrate which is to be plated.

What is it used for?

This treatment is effective for a variety of metals and alloys including brass, copper and steel – these are the most common that are used in modern technical applications. Its most common use is in situations where the component needs to be resistant to corrosions such as hydraulic piston rods, motorcycle forks, and gear shafts used in the automotive sector.

Polishcraft’s metal polishing

Polishcraft initially began as a polish only service in 1983 giving us plenty of time to perfect our technique over the years.

For those that are unaware of what metal polishing entails; it is simply the name given to plated and solid items that have been cleaned and stored to achieve a shiny and smooth surface.

The metals that can have polishing include:

– Aluminium
– Chrome
– Copper
– Gold
– Nickel
– Silver

Polishing can be done through a variety of tools which include buffers & polishers, acids, solvents and more.

Types of metal polish

– Aluminium and stainless steel will oxidise on the surface acting as a protector from corrosion – we proceed to remove the oxidisation and smooth it down to achieve a shiny finish much like chrome.

– Metal polishing for chrome is slightly different as it isn’t polished but cleaned. Because chrome doesn’t oxidise as much as other metals, it is unnecessary to polish.

– If metals are pitted or scratched, it is best to smooth the metal prior polishing. To smooth a metal, use wet dry paper or wet sand.

– The metal polishing will finish with buffing which is done by a rotating wheel that will hold a buffing compound that could potentially contain a mixture of wax and/or fine abrasives.

Our metal polishing in Birmingham offers a joint service of polishing and hard chrome plating as well as just polishing.
