The ability of the laser to produce a controlled and intense source of heat is the key characteristic which has led to its recent emergence as an important manufacturing tool. In this paper we have discussed the different techniques of laser materials processing and have given a brief description of their important applications.

The oxidation and corrosion of mild steel coated with chromium powder followed by laser treatment has been investigated. Chromium powder was deposited on mild steel surface using atmospheric plasma spraying. The chromium-coated surface was irradiated separately using a pulsed Nd:YAG laser and a continuous CO2 laser. The oxidation tests were carried out in air at 700°C and anodic polarization tests in 1N H2SO4 solution. There was significant difference in the morphologies of the surface alloys formed using CO2 laser and Nd:YAG laser. Samples treated with CO2 laser showed better oxidation resistance whereas the surface alloys formed using Nd:YAG laser showed poor oxidation resistance. Anodic polarization tests carried out on samples laser-treated with CO2 laser showed improved corrosion resistance.
