Abrasive Wear Characterization for Different Grades of Tungsten Carbide Material

Abstract — A present study has been conducted on the tribological properties of different grades of tungsten carbide material by carrying out an abrasive wear test using ASTM G65. The composition of different grades of tungsten carbide was varied and binder content ranged from 6 to 20Wt%. Five graded compositions were studied which includes cobalt binder and alloy binder. Abrasive wear was investigated by conducting three body abrasive wear test, so that we can rank the material inturn we can select the best grade for real time application like wire drawing process. There are many test procedures available for abrasion wear. Not much work has been carried out in comparing the results of these procedures. Real time applications like Wire Drawing are much more complex in terms of abrasion wear compared to a standard test. This work is an attempt to study the relation between the standard test and real time application like wire drawing process for five different grades like Grade-A, Grade-B, Grade-C, Grade-D and Grade-E which vary by binder percentage and grain size
