Treatments consist in polishing steel to a high mirror gloss or brushing it to achieve a matt surface. Other types of steel finishes have recently become possible. Today, we can create a gilded surface finish or use the brand new IPG method. Achieving other colour shades is possible using the same method, with the result being red gilding IPGR, trendy matt black, or glossy IPB.
Ion plating (IP) is physical vapour deposition (PVD). Simply put, ion plating applies periodic bombardment of the surface of the case or bracelet to lay down layers of carbide. Everything takes place in a vacuum at high temperatures. This layer is several times harder than what was possible to achieve using earlier methods. It means this layer is exceptionally abrasion-resistant and long-lasting. Ion plating is also used for tools, machining tools and other objects.
