硼化鉬具有很高的硬度和較低的相對摩擦系數，化學穩定性，耐磨耐腐蝕，抗磨損，該材料被應用在滑動摩擦表面，起著減磨作用。硼化鉬熔點在2600℃，可以做耐高溫噴涂層。耐磨性能好，耐熱、抗氧化、電阻與溫度有線性關系的特種合金，可用于金屬陶瓷、耐磨涂層、高溫電阻、坩堝內襯、填空噴鍍和耐腐蝕化工設備，過渡金屬硼化物在技術應用中是傳統硬質合金和超硬材料的潛在替代品。

Molybdenum boride has high hardness and low relative friction coefficient, chemical stability, wear resistance, corrosion resistance, wear resistance, the material is used in sliding friction surface, play a role in reducing wear. Molybdenum boride melting point at 2600℃, can be made high temperature resistant coating. Special alloys with good wear resistance, heat resistance, oxidation resistance and a linear relationship between resistance and temperature can be used in cermet, wear resistant coating, high temperature resistance, crucible lining, filling spraying and corrosion resistant chemical equipment. Transition metal borides are potential substitutes for traditional cemented carbide and superhard materials in technical applications.
