Wallwork Cambridge UK is part of the Wallwork Group of companies specialising in hard coatings, heat treatment, machine build, vacuum brazing and other services.

Using PVD coatings on metal components and tools is becoming increasingly popular and necessary, as these items are required to perform tasks that are beyond the capabilities of the base metal.

This is where Physical Vapour Deposited (PVD) coatings are particularly useful. Their hardness is typically 3-4 times harder than heat treated steel, and because the coating follows the component geometry exactly and istypically1 to 4microns thick, often no tolerance change is necessary.
