用TiN 或TiC 涂层涂在多边形刀片上以提高刀具前面或后面的耐磨性,在工业中得到了日益广泛的应用。近来对在氮化物的晶格中加入硼来改善TiN 的机械性能,特别是改善其硬度和化学成份的可能性进行了研究。由于在热压或烧结过程中不能得到Ti—B—N 三元成份,因此创造了化学喷涂法。利用这种方法获得了带面心立方晶格的(接近TiN 的晶格)或带六方晶格的(接近TiB_2晶格)类似成份。所进行的大量研究工作表明,在1200—1500℃温度下,可以得到立方氮化硼;温度更高时,这种材料便丧失其稳定性。根据用作原料
The use of TiN or TiC coatings on polygonal inserts to increase the wear resistance of the front or the back of the tool is gaining more and more widespread use in the industry. Recent research has been conducted on the addition of boron to the nitride lattice to improve the mechanical properties of TiN, in particular its hardness and chemical composition. The chemical spraying method was created because Ti-B-N ternary components were not obtained during hot pressing or sintering. Using this method, similar elements with face-centered cubic lattice (near TiN lattice) or hexagonal lattice (near TiB 2 lattice) were obtained. A large number of studies carried out show that cubic boron nitride can be obtained at a temperature of 1200-1500 ° C; at higher temperatures, the material loses its stability.
