Applications of laser for ceramic alloying on metallic surfaces

Summary Ceramic and metallic materials were alloyed and cladded on a C40 steel by means of a CO₂ laser heat source. The main objectives of the research were to obtain a surface modification of the C40 steel in order to increase its wear resistance and to develop a repeatable coating process of potential industrial application. In the following sections, the laser coating process (including experimental equipment and working parameters) and the most important metallurgical results are described.
