We study the microstructure of deposited coatings formed by a composite material based on PG-10N-01 self-fluxing alloy and modified with a mechanically activated composite material obtained as a result of the self-propagating high-temperature sintering process. By the X-ray phase diffraction analysis, in the structure of the coating, we detect the presence of titanium diboride (TiB2), nickel boride (Ni3B), titanium oxide (TiO), and iron oxide (Fe3O4) inclusions distributed over the nickel matrix. It is demonstrated that the modifying addition promotes not only the refinement of structure in the course of electric-arc deposition but also the elevation of the levels of hardness and microhardness of the deposited layer and a 1.5-fold increase in the abrasive wear resistance as compared with the wear resistance of PG-10N-01 alloy.

含弥散相夹杂物的 Ni-Cr-B-Si 系沉积材料的显微组织和耐磨性

我们研究了由基于 PG-10N-01 自熔合金的复合材料形成的沉积涂层的微观结构，并用自蔓延高温烧结过程获得的机械活化复合材料进行改性。通过 X 射线相衍射分析，在涂层的结构中，我们检测到分布在镍上的二硼化钛 (TiB2)、硼化镍 (Ni3B)、氧化钛 (TiO) 和氧化铁 (Fe3O4) 夹杂物的存在矩阵。结果表明，改性添加不仅促进了电弧沉​​积过程中组织的细化，而且提高了沉积层的硬度和显微硬度水平，耐磨性提高了1.5倍。具有PG-10N-01合金的耐磨性。
