摘要

A beta-stabilized titanium alloy was created in this work using two different laser cladding technologies and laser sources. Tungsten carbide WC was used as an additive to the initial Ti64 powder and contributed to both the formation of secondary solid particles as a result of in-situ synthesis and alloying of the titanium matrix with tungsten, which caused stabilization of the titanium matrix. It is shown how different laser types affect the properties and microstructure of the material. A study was carried out of the influence of the type of laser source on the evolution of the phase composition of the metal-ceramic material Ti64–WC using synchrotron radiation. It has been shown that the β-stabilized metal-ceramic composite Ti64–WC with a mass content of WC 40% has better resistance to fracture under high-speed impact compared to titanium alloy Ti64.
