The aim of surface treatment can be to improve corrosion resistance, durability, lubricity, aesthetics or other properties. Depending on the type of material surface and the desired properties, different surface treatment techniques can be used. It is important that the treatment is carried out precisely and with care in order to achieve an optimal result.
