The process of formation of a multilevel multilayer B₄C – Ti-6Al-4V cermet coating by the method of SLM is studied. The coating is characterized by presence of heterogeneous zones differing in the mechanical properties. It is shown that the use of the B₄C – Ti-6Al-4V powder mixture with ceramics concentration 20 wt.% is not expedient, because it causes deficit of the metallic matrix and formation of cracks. At 10 wt.% ceramics in the powder mixture with alloy Ti-6Al-4V the wear resistance of the coating increases by a factor of 4.2.

SLM法形成B 4 C – Ti-6Al-4V金属陶瓷涂层

研究了采用SLM法形成多层多层B ₄ C – Ti-6Al-4V金属陶瓷涂层的过程。该涂层的特征在于存在机械性能不同的异质区域。结果表明，不宜使用陶瓷浓度为20 wt％的B ₄ C – Ti-6Al-4V粉末混合物，因为它会导致金属基体缺乏和形成裂纹。在与Ti-6Al-4V合金混合的粉末混合物中，陶瓷含量为10％（重量）时，涂层的耐磨性提高了4.2倍。
