Paper Abstract

Observations are reported on the microstructure, defects and diffusion in AISI 1018 steel, surface alloyed with chromium by 2KW continuous wave CO2 laser. The nature of alloying and chemical diffusion profile as a function of intertrack separation distance affects the final content of alloying element in surface layer. The ratio of number of laser tracks to width can be optimized to get minimum of cracking, maximum hardness and most uniform alloying of species.
