Surface Hardening of Steel by Electron-Beam Cladding of Ti+C and Ti+B4C Powder Compositions at Air Atmosphere

摘要

Structural investigations of the materials obtained by surface alloying with titanium containing powder compositions using industrial electron acceleration were carried out. It was revealed that hardened particles of titanium carbides and borides were formed as a result of high-energy treatment. The highest value of materials studied microhardness was about 8.4 GPa. Friction testing against fixed abrasive particles showed that electron-beam cladding of the titanium and graphite mixture conduced to increasing material wear resistance by a factor of three.
