等离子喷涂涂层应用于炼钢、航空航天、造纸等各种工业领域。低压等离子喷涂（LPPS）技术的发展显著提高了涂层的可靠性。由于CoNiCrAlY合金在高温下具有优异的抗氧化和抗腐蚀性能，广泛应用于各种工业领域，本文报道了对LPPS CoNiCrAlY涂层显微组织的一系列研究结果，特别是着重讨论了原始粉末材料与涂层显微组织的差异以及波浪状层状结构的形成机理。
Plasma spray coatings are applied to steel making, aerospace, paper making and other various industrial fields. The reliability of the coating has been remarkably improved by the development of low pressure plasma spray (LPPS) technique. The present paper reports some preliminary results from a series of investigations on the microstructures in LPPS CoNiCrAlY coating, especially focuses on the difference of microstructures between the raw powder material and the resultant coating and the formation mechanism of the wavy laminated structure, since the CoNiCrAlY alloy has excellent oxidation and corrosion resistance at high temperature and is widely used in the various industrial fields mentioned above.
