Abstract:

Strength, surface finish and rolling contact fatigue life were determined on two grades of hot pressed silicon nitride after a total of twenty- seven different surface finishing procedures. Rolling contact fatigue lives of silicon nitride with selected smoother finishes tested at 800 ksi Hertz stress were an order of magnitude longer than those obtained on the M50 bearing steel controls and more than twice as long as the best results previously obtained on silicon nitride.
