Crushing Strength of Cemented Tungsten Carbide Pistons

摘要

The crushing strength of various grades of cemented tungsten carbide pistons was determined as a function of the ratio of unconstrained length to diameter (L/D). There was little effect for pistons whose ends were unsupported, but a dramatic increase in crushing strength with decreasing L/D for pistons whose ends were supplied with interference-fitted binding rings. Tests with pistons of different diameter but constant L/D suggest the absence of any effects dependent on the diameter of the pistons. (Author)
