Abstract

The paper aims the influence of the laser radiation parameters on superficial layers of carbon and alloy improvement steels. Geometry and depth of penetration of radiation effects are studied by optical and electronic microscopy. It aims also the distribution of components on the affected film thickness by laser energy, analyzed by EDAX and variation of mechanical properties..
