以平均粒度 0 13μm的TiC0 7N0 3 超细原料制备超细TiCN基金属陶瓷 ,当用普通真空烧结炉烧结时 ,合金中存在大量的孔隙 ,造成合金性能非常差。控制工艺过程中的吸氧和真空烧结时有效的释放低熔点挥发物和有害物质 ,以及采用热等静压 ,可以获得性能优异的超细金属陶瓷材料。 Ultrafine TiCN-based cermets were prepared from TiC0 7N0 3 ultrafine raw materials with an average particle size of 0 13μm. When sintered in an ordinary vacuum sintering furnace, there are a large number of pores in the alloy, resulting in very poor performance of the alloy. Control of the process of oxygen and vacuum sintering effectively release low melting point volatile and harmful substances, and the use of hot isostatic pressing, you can get excellent performance of ultrafine cermet material.
