Paper Abstract

Different laser processing methods used to modify the surface properties of materials are discussed. Metallographical (optical, SEM, TEM), microprobe, x-ray diffraction, wear resistance and microhardness investigations of 3Cr (0.26%C/3.11%Cr/1.98%Mn/0.5%Mo), 10Cr (0,20%C/9,85%Cr/1.0%Mn/0.5%Al) T15 high-speed tool steel, and ductile cast iron surface treated by a continuous CO2 (with different power), Nd-YAG and ruby pulsed lasers radiation, are presented as an illustration showing the benefits of laser application in modification of material properties. In addition laser alloying of 0.30% carbon plain steel with tungsten is also described.
