Role of Microstructure in Hertzian Contact Damage in Silicon Nitride: II, Strength Degradation

Ti3SiC2has been widely investigated for their intriguing physical and mechanical properties [1]. In the past decades, dense and pure polycrystalline Ti3SiC2has been fabricated by some techniques [1,2]. Studies on deformation and fracture behavior at elevated temperature showed that Ti3SiC2exhibited substantial plasticity with high strength [3]. It is pointed out that Ti3SiC2can be possibly used for some contact applications, such as bearings, for its relative high compression strength, self-lubricating and machinability [1]. In the present paper, fatigue crack-growth rates and Hertzian contact damage of Ti3SiC2were studied. Shielding ability of Ti3SiC2was investigated specially in the small crack region. Damage evolution and strength degradation under Hertzian contact were studied to reveal damage behavior and mechanisms in Ti3SiC2.

A study is made of the damage resistance and strength degradation of nitrided pressureless sintered (NPS) silicon nitride ceramics. The silicon nitride is prepared by cost-effective NPS process combining by nitridation and consecutive pressureless sintering. Contact testing with spherical indenters is used to characterize the damage response. Examination of the indentation sites indicates a quasi-plastic damage modes are observed. Bend tests on specimens containing quasi-plastic contact damages reveal those materials to be not susceptible to strength degradation.
