Notes:
High quality TiN/Ti multi-layers have been successfully obtained on a carbon steelsubstrate by double glow plasma surface alloying technique (DGP). The TiN/Ti multi-layersconsists of deposition layer and diffusion layer, and then on its surface TiN film (PVD) is depositedto form TiN/TiN/Ti compound multi-layers. In addition, studies were carried to compare TiN/Timulti-layers, TiN/TiN/Ti compound multi-layers and TiN film (PVD) directly deposited on thesurface of the carbon steel and their microhardness and dry friction-abrasion properties were alsoinvestigated. The results show that the thickness of TiN/Ti multi-permeated layers is above 10*m;Ti and N concentrations change gradually along the depth of alloying layer. TiN/Ti multi-layers andsubstrates are metallurgically bonded. Preferred orientation of TiN/Ti multi-layers is crystal surface(200). The hardness of the TiN/Ti multi-permeated layers ranges up 2200HV, its average frictioncoefficient is lower, abrasion crack is shallower and wear resistance better
