【Abstract】 Ceramic matrix composites(CMC) is an ideal engine material. By increasing the tenacity and changing the structure of the material, it becomes quite wearable and heat-resistant, which makes it an ideal choice for machine parts whose primary concern is wearability and heat-resistance.In this paper the performance and production of CMC was expounded. The prospective and development of CMC in engine parts as well the difficulties was discussed.更多还原
