Fatigue and Contact Damage of Layered Machinable Ti3SiC2 Ceramics


Article Preview

Ti3SiC2 has been widely investigated for their intriguing physical and mechanical properties [1]. In the past decades, dense and pure polycrystalline Ti3SiC2 has been fabricated by some techniques [1,2]. Studies on deformation and fracture behavior at elevated temperature showed that Ti3SiC2 exhibited substantial plasticity with high strength [3]. It is pointed out that Ti3SiC2 can 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 Ti3SiC2 were studied. Shielding ability of Ti3SiC2 was 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.
