Comparing the surface hardness of mild steel processed with CO₂ and fibre lasers

The microhardness of low carbon mild steel was analysed after surface treatment by using carbon dioxide CO₂ and Fibre laser for comparison. Identical input parameters were used to compare the increase between the as-supplied material hardness and the treated surface. Microhardness testing was used t...
