Abstract
In this paper the friction and wear behavior of laser-modified layers on the surface of carbon and stainless steel was studied. Laser modification of metals is a recent technique whereby the friction and wear properties of metals can be improved. Using various methods (laser transformation hardening, laser cladding, laser alloying, etc.) to treat the surfaces of metals, the chemical compositions, phases and microstructures of metal surfaces can be modified to form supersaturated solid solutions (martensite, etc.) metastable phases (austenite, etc.) and special chemical compounds (carbides, boron compounds, etc.). In this way their hardness and anti-adhesion, anti-scratching and plastic deformation resistance abilities may be improved. As a result, the sliding and fretting wear resistances of metals under dry friction and oil lubrication conditions may be increased. The experimental results also show that residual austenite increases the wear resistance. Investigation of the interaction between the modified surface and lubricating oil additives is very important.
