Abstract

The application of surface engineering techniques to improve the surface properties of carbon steels using high powered lasers for transformation hardening and surface melting is well established. Based on previous research, a TIG torch technique has been explored for the surface modification of steels as a much cheaper option to lasers. Different studies in the area of optimal heat input, ceramic particle size and preplacement of particle size have been conducted in order to obtain a crack and porous free melt zone with high hardness and deep enough for wear resistance.∼5μmor ∼75μmSiC particulates were preplaced on a microalloyed steel. Single track surface zones were melted by a tungsten inert gas torch, and the effect of two
heat inputs, 420 and 840 Jmm−1, compared. The results showed that the samples melted using 420 Jmm−1 were crack-free. Si particles were also preplaced on a SiC processed microalloyed steel in order to decrease
SiC dissolution by generating a high Fe–Si liquid which protects the ceramic.
