Abstract

Continuous wave carbon-dioxide (CW CO2) laser was employed to study the hardfacing characteristics of cladding S42000 stainless steel powder on K02600 mild steel. The cladding layer was overlapped track-by-track and then layer-by-layer. Identical hardfacing on mild steel by submerged are welding (SAW) was also studied. The wear test, microhardness test, metallographic analysis, scanning electron microscope (SEM) analysis, and electron probe microanalysis (EPMA) mere subsequently carried out to compare these hardfacing techniques. The results showed that the hardness of laser cladding mas twice the hardness of SAW cladding, and the results indicated that the former had superior wear properties to the latter.
