Effect of Carbide on the High Stress Abrasive Wear of High Chromium Cast Iron
The abrasive wear test with different loads was carried for high chromium white cast iron on the wear test machine.The protect affection of carbide on the matrix and the carbide surface stripped was analyzed.It is shown that the wear lose was slow when the load was under a specific value,but it was increased fastly when the load is increased over a specific values.With the increase of the wear load,the small size carbide stripped from the surface firstly,and then the big size carbide stripped and mashed when the load keep on increasing,So in order to increase the wear resistance of the high chromium cast iron,it is helpful that the carbide hold in suitable size and distribution equably in the iron.
