Abstract

Abstract: For the purpose of selecting the better strengthening material welded on bit teeth,the various sizes of spheroidal sintering tungsten carbide and the granular casting tungsten carbide were tested by abrasive wear,to estimate their wear resistance.Using the Nickel base metal as solder,the hard alloy was welled on the 20 Ni 4 Mo in fine vacuum.The test was performed on a series of shock loads,the abrasive consists of quartz sands,water annd a little suspension.The friction loss was weighted in the balance.It ...

Key words: bit teeth, material, impact, wear
