采用超音速等离子喷涂技术将新型多元铝青铜合金粉体喷涂在45号钢基体表面。运用XRD、SEM、EDS、EPMA等手段分析了涂层的组织特点及元素分布情况。结果表明,超音速等离子喷涂层主要由Cu9Al4、AlFe3、AlFe等相组成;涂层元素分布均匀;超音速等离子喷涂层硬度高于传统等离子喷焊层;涂层的结合强度为59.3MPa。可见,经过工艺参数的优化,超音速等离子喷涂可以制备出类似于多元铝青铜合金的易氧化涂层。
The use of supersonic plasma spraying technology will be the new multi-aluminum bronze alloy powder sprayed on the 45 steel substrate surface. The microstructure and elemental distribution of the coating were analyzed by XRD, SEM, EDS and EPMA. The results show that the supersonic plasma spray coating mainly consists of Cu9Al4, AlFe3, AlFe and other phases; the coating elements are evenly distributed; the supersonic plasma spray coating hardness is higher than the traditional plasma spray coating; the bonding strength of the coating is 59.3MPa. Visible, after the optimization of process parameters, supersonic plasma spraying can be prepared similar to the multi-element aluminum bronze alloy easy oxidation coating.
