【摘要】 采用低压等离子喷涂方法在单晶镍基高温合金上制备出组织均匀致密、结合良好的Ｎｉ－Ｃｏ－Ｃｒ－ＡＬ－Ｙ－Ｔａ涂层．运用光学显微镜，ＥＰＭＡ，ＳＥＭ，ＸＲＤ等分析手段对喷涂态和热处理态涂层的相结构、相成分及界面结构进行了分析．更多还原

【Abstract】 The Ni-Co-Cr-Al-Y-Ta coatings On the nickel base superalloy with dense structure,homogeneous composition and good bondstrength have been prepared by the low pressure plasma spraying(LPPS)technique.EPMA,XRD and optical microscopy have been used for analyzing the phase structure,phase compositions and metallography of both the assprayed and heat-treated coatings.更多还原
