为了弄清（Ti， B）N涂层碳化物在切削熔化材料（SCr420H）或烧结钢时的刀具磨损情况，对（Ti， B）N涂层碳化物刀具的磨损过程进行了实验研究。所述涂层硬质合金刀具的母材为硬质合金。结果表明：(1)(Ti， B)N涂层硬质合金刀具的显微硬度和临界划痕载荷均高于TiN涂层硬质合金刀具。(2)在切削SCr420H时，（Ti， B）N涂层硬质合金刀具的磨损过程比TiN涂层硬质合金刀具慢。(3)在切削烧结钢时，（Ti， B）N涂层硬质合金刀具的刀具磨损与TiN涂层硬质合金刀具的刀具磨损大致相等。然而，在高速切削烧结钢时，（Ti， B）N涂层碳化物刀具的磨损过程要比（Ti， B）N涂层碳化物刀具快。发现（Ti， B）N可以作为刀具的涂层材料。
In order to clarify the tool wear of (Ti, B)N coated carbides in the cutting of melted material (SCr420H) or sintered steel, the wear progress of (Ti, B)N coated carbides tool is investigated experimentally. The base metal of the coated carbides tool is cemented carbides. The main results obtained are as follows: (1) Both the micro-hardness and the critical scratch load of (Ti, B)N coated carbides tool are higher than those of TiN coated carbides tool. (2) In the cutting of SCr420H, the wear progress of (Ti, B)N coated carbides tool is slower than that of TiN coated carbides tool. (3) In the cutting of sintered steel, the tool wear of (Ti, B)N coated carbides tool is about equal to that of TiN coated carbides tool. However, in the high speed cutting of sintered steel, the wear progress of (Ti, B)N coated carbides tool is faster than that of (Ti, B)N coated carbides tool. It is found that the (Ti, B)N can be used as a coating material of cutting tool.
