近年来,人们对耐热、耐腐蚀、耐摩擦材料的需求越来越迫切.但是这些要求在金属材料的实际使用中却往往难以得到满足.因此,将较之金属材料特性更优良的陶瓷来作为结构材料的想法便成了人们研究的课题. 一般地说,陶瓷较脆,用作结构材料的可靠性较差.目前,将陶瓷和韧性较高的金属材料相结合,使两者的特性揉合在一起组成的组合材料,部分已付诸实用.而某些陶瓷使用时
In recent years, the demand for heat-resistant, corrosion-resistant and friction-resistant materials has become more and more urgent, however, these requirements are often not satisfied with the actual use of metal materials. Therefore, The idea of as a structural material has become the subject of research.Generally speaking, the ceramic is more brittle, the reliability of the structural material is poor.Currently, the combination of ceramic and high toughness of the metal material, so that both the characteristics Part of the combination of materials that have been kneaded together has been put into practical use. While some ceramics are in use
