Laser alloying and cladding for improving surface properties

Various approaches to laser surface alloying have been studied, including the use of predeposited layers as the source of alloying material as well as the technique of direct powder injection. The study was conducted with the aim to compare different techniques of laser alloying in order to reveal their relative advantages and disadvantages and to establish criteria for choosing optimum irradiation conditions for each laser alloying technique.
