APS/HVOF热喷涂WC基金属陶瓷涂层的微观组织与性能
APS HVOF WC-10Co-4Cr WC-17Co 微观组织
2017/3/29
WC基涂层由于具有较高的硬度、优异的耐磨性、较好的抗腐蚀性，广泛应用于石油等工业中提高零件的磨损和腐蚀性能。随着现代化工业中工件服役环境日趋复杂，对制备性能优异的WC基涂层要求越来越高。在热喷涂技术中，热喷涂大气等离子热喷涂(APS) 喷涂温度范围广，可以提高至数万温度，在喷涂难容材料方面具有无与伦比的优势，而超音速火焰喷涂(HVOF)由于具有较高的焰流速度，粒子动能较高，同时由于喷涂过程中N2等...
运用超音速火焰喷涂(HVOF)和等离子喷涂(APS)技术在7005 铝合金表面制备了WC-Co/ NiCrBSi 复合涂层,分析了2 种技术所制备复合涂层的微观结构,研究了其在高温条件下的摩擦磨损行为与机制。结果表明:采用HVOF 技术制备的复合涂层孔隙率仅为APS 制备复合涂层的28. 9%;其显微硬度(838. 4HV0. 5)以及与基体间元素扩散层厚度( Al:13. 17 μm, Ni:1...
