Abstract

The results of studying microstructure and hardness of surface layers of nickel alloy welded on titanium α + β alloy using fiber laser after their combined hardening under the effect of laser radiation are presented. Laser cladding makes it possible to form coatings with high hardness and quenching structures in surface layers of titanium alloy. Hardness of welded metal after the high-speed cooling from the melt temperature on the titanium substrate surface is larger than the density of martensite alloy formed in the titanium alloy after quenching.
