由于碳化钛具有很高的硬度、较小的摩擦系数(仅为钢的1/5～1/7),因此,工模具经表面沉积碳化钛后其使用寿命可提高几倍到几十倍。本刊1977年第8期已介绍过真空溅射沉积碳化钛的基本工艺及原理。该工艺的特点是处理温度在600℃以下,因此可适用于整体硬质合金刀具,而且也适用于焊接结构的硬质合金和高速钢刀具。该工艺已于1979年1月通过鉴定,现将此工艺用于手表加工生产上的情况做一简介。
Because titanium carbide has a high hardness, a small coefficient of friction (only steel 1/5 ~ 1/7), therefore, the mold after the surface deposition of titanium carbide life can be increased several times to several times. This issue in 1977 No. 8 has been introduced by vacuum sputtering titanium carbide deposition of the basic technology and principles. The process features processing temperatures below 600 ° C and is therefore suitable for use with solid carbide tools as a whole but also for carbide and HSS tools with welded structures. The process was passed in January 1979 identification, now this process for the production of watches and clocks to make a briefing on the situation.
