Effect of Niobium on the Microstructure and Properties of High Chromium Cast Iron for Slurry Pump
The effect of niobium on the properties of a kind of high chromium cast iron for slurry pump is analyzed and discussed by means of comparative experiments.The mechanical properties,hardness and wear resistance of the material are measured respectively,and the structure is analyzed.The results show that the addition of niobium has a significant change in the morphology of carbides in high chromium cast iron,which improves the mechanical properties and also improves the wear resistance of the material.
