Wear Behaviors of Cemented Carbide Cermet YG8B under Different Concentrations of Abrasive Slurries from Carborundum, Corundum and Silica Sands

摘要：

This work investigated the wear behavior of cemented carbide cermet YG8B under different concentrations of abrasive slurries using a modified ASTM B611 wet sand rubber rimmed wheel test system with a load of 225 N. The angular sand abrasives involved in carborundum,corundum and silica with particle size of about 350 μm,and were dispersed into water with different mass fractions. It was found that,with increasing sand concentration in slurry,the wear loss of the cermet samples increased, and with the increase of duration time,the wear loss of the cermet samples also increased. Under the same conditions,the cermet samples presented the biggest wear loss with carborundum as abrasive. On the basis of the observations on the wom surfaces by scanning electron microscope and 3D white-light interfering surface profiler,the wear mechanism of the cermet samples was proposed,which includes in extensive plastic deformation,groove,fracture and pullout.
