Laser surface alloying (LSA) of AISI 316L stainless steel with various compositions of Ni and SiC for different laser parameters was investigated. The hardness of the LSA layer was found to be a strong function of silicon content. The maximum hardness achieved was 733 HV. Columnar dendrites, equaxial dendrites and cellular structure were observed in the resolidified microstructure. XRD and EPMA studies were used to find different phases and elemental concentration, respectively.
