ActiveSilicon nitride ceramics—Test method for rolling contact fatigue at room temperature—Balls-on-flat method
氮化硅陶瓷 室温下滚动接触疲劳试验方法 球板法
Application Summary AI generated
This standard specifies a test method for evaluating the rolling contact fatigue resistance of silicon nitride ceramic materials at room temperature using a balls-on-flat configuration. It is applied in the quality control and material selection for advanced ceramic components, particularly for bearing balls and rolling elements used in high-performance mechanical systems. The method is critical for industries such as aerospace, automotive, and precision machinery where ceramic bearings must withstand repeated cyclic loading without surface failure.
