摘要

摘要本文主要研究基底预热对采用直接金属沉积法用 B4C 颗粒增强 TI-6AL-4V 合金制成的金属陶瓷涂层结构的影响。首次获得了 B4C 质量分数为 15% 的涂层。结果表明，基底预热使生产无裂纹的金属陶瓷涂层成为可能。在摩擦学测试中，与 B4C 质量分数为 10% 的涂层相比，金属陶瓷涂层的磨损疤痕体积减少了 8 倍。

EFFECT OF SUBSTRATE PREHEATING ON THE CERMET COATING STRUCTURE OBTAINED USING ADDITIVE TECHNOLOGIES

Abstract

This paper is devoted to the influence of substrate preheating on the structure of cermet coatings made of TI–6AL–4V alloy reinforced with B₄C particles using direct metal deposition. Coatings with a 15% mass fraction of B₄C were obtained for the first time. It is shown that substrate preheating makes it possible to produce cermet coatings without cracks. In tribological tests, the wear scar volume of the cermet coating decreased by a factor of eight compared to the coating with a 10% mass fraction of B₄C.
