The Research of Carbon Construction Steel at Laser Alloying

Relevance: The theme of machine components case-hardening when heated by a laser ray has been and remains currently relevant. Laser case-hardening is characterized by a number of exclusive advantages: hardening of hard-to-reach surfaces, ensuring local hardening, including “spot” one when a continuous layer of fragile material vulnerable to cracking and destruction doesn’t form; the lack of deformations and warping of processed parts as well as finishing operations; getting desired properties both mechanical and chemical ones by introducing different elements in the uppermost layer of a product at its melting by a laser ray, i.e. at implementing laser alloying.
