Abstract (en)

[origin: WO02077312A2] The invention relates to a method for increasing internal pressure stress or for reducing the internal tension stress of an outer or outermost hard material layer that is applied on a hard metal, cermet or ceramic substrate body by means of CVD, PCVD or PVD. After coating, the coated substrate body is subjected to dry shot blasting using a granular shot blasting agent, which, according to the invention, has a maximum diameter of 150 mu m.
