Abstract The present investigation deals with the fabrication of a novel thermally sprayed coating using a diamond reinforced molybdenum feedstock. Molybdenum powders were ball-milled with 10 wt% mono-crystalline diamond particles to produce a powder feedstock. Both milled and as-received powders were deposited on steel substrates using air plasma spraying to produce coatings with a thickness in the range of 250–280 μm. Characterisation of the coatings was performed in terms of micro-structure, phases, hardness, elastic modulus and residual stress. Retention of diamond in the composite coating was confirmed using Raman imaging. Micro-hardness and elastic modulus of coatings improved with diamond reinforcements.

等离子喷涂金刚石增强钼涂层

摘要 本研究涉及使用金刚石增强钼原料制造新型热喷涂涂层。钼粉与 10 重量％的单晶金刚石颗粒一起球磨以生产粉末原料。使用空气等离子喷涂将研磨和原样粉末沉积在钢基材上，以产生厚度在 250-280 μm 范围内的涂层。根据微观结构、相、硬度、弹性模量和残余应力对涂层进行表征。使用拉曼成像确认复合涂层中金刚石的保留。金刚石增强剂改善涂层的显微硬度和弹性模量。
