日本大阪大学产业科学研究所所属的高功能极限材料研究中心,由山村等人共同研制出先在金属上涂镀陶瓷膜,然后再进行HIP(热气静水压)处理的方法,从而大幅度地提高了金属与陶瓷的结合力。目前已采用的陶瓷镀层材料只是其中一部分,硬度和结合力还有些问题,因此使用还不太普遍。 HIP处理材料,硬度、结合力都比原有的材料提高三倍以上。在零件有耐磨性要求的领域中,如涡轮叶片、活塞、涡轮充电器等产品,广泛需要这种性能。陶瓷比金属的加工性能差,而且脆,因而不能充分发挥出自身应有的作用来。在这种情况下,应该加快研制出金属与陶瓷的复
Japan’s Osaka University Institute of Industrial Science belongs to the high-performance limit material research center, jointly developed by the village of Yamamoto and others on the metal coating ceramic film, and then HIP (hydrostatic hydrostatic) method, which greatly improved The combination of metal and ceramic. Currently used ceramic coating material is only part of the hardness and bonding there are some problems, so the use is not so common. HIP treatment materials, hardness, binding force than the original material to improve more than three times. This area of performance is required for a wide range of applications where wear parts such as turbine blades, pistons, turbo chargers and the like are required. Ceramic than metal processing performance is poor, and brittle, and therefore can not give full play to its due role. In this case, we should speed up the development of metal and ceramic complex
