Flaking of PEEK under one-point rolling contact fatigue using Al2O3 ball

Flaking of PEEK under one-point rolling contact fatigue using Al2O3 ball

The growth of flaking as tribological fatigue failure in PEEK was investigated through the one-point type rolling contact fatigue test between a machined PEEK polymer shaft and an alumina bearing's ball. Due to Hertzian contact of cyclic compressive stress, the subsurface fatigue cracks in the...
