Study on Electron Beam Alloying Micro-Structure and Wear Performance of 3Cr2W8V

Abstract:

Ti and TiN were deposited on mold steel 3Cr2W8V by PVD, then processed with the technology of electron beam surface alloying. The microstructure of modified and the influence of modified layer on wear performance of 3Cr2W8V were studied. The result shows that the section hardness of coating Ti material has increased by 35% at most when the times of treatment reach 25, the distribution of the section hardness is waved, the pick point of section hardness is at depth of 100μm to 200μm, The friction of coating Ti layer is decrease by 50% at most when the times of treatment reach 20, and the abrasion loss is totality descend by about 80%;the section hardness of coating TiN material has increased by 35% at most also when the times of treatment reach 25, the pick point of section hardness is at depth of 150μm to 250μm, the friction factor of material is waving with descend while the times of bombardment increased; the abrasion loss is totality descend by about 90%.
