Blades are the key parts of turbines. The materials used for making blades have many excellent performances such as high intensity, corrosion resistant and temperature resistant. They are of hard to machine materials. However, there is little information available in the literature related to abrasive belt grinding blades materials. And its mechanisms have not yet been fully explained. This paper aims to make a contribution to the understanding of the wear mechanisms of the abrasive belt and its influence factors. A series of tests were conducted on 1Cr13 stainless steel. The surface roughness and the surface topography of abrasive wear were observed. The influences of grinding force and grinding time on surface roughness were discussed. The wear mechanisms are revealed based on the model of abrasive grain’s wear. It revealed that existence of an optimum surface roughness reachable dependent of the grinding force and grinding time. It has also been shown that the type of abrasive and grinding depth have great influence on abrasive wear. |
