采用空气等离子喷涂技术在镍基合金表面制备了以纳米氧化锆为添加剂的二硅化钼(MoSi2)基复合涂层，并用X射线衍射仪和扫描电子显微镜对涂层的物相组成和显微组织进行了表征。在1100℃下，比较了复合涂层和纯MoSi2涂层的高温磨料磨损性能。X射线衍射结果表明，在喷涂过程中，T-MoSi2和H-MoSi2之间存在相互转变，部分富钼相是由于氧化而形成的。纳米氧化锆的加入可以提高片间的结合力，防止片间界面开裂，净化晶界。与纯MoSi2涂层相比，复合涂层具有更好的耐磨性。纳米氧化锆的加入可以有效地缓解MoSi2涂层的粘着磨损和脆性剥落。
Molybdenum disilicide (MoSi2)-based composite coating using nano-ZrO2 as an additive was deposited on a nickel-based alloy by air plasma spraying, and the phase composition and microstructure of the composite coating were characterized by x-ray diffraction (XRD) and scanning electron microscope. The high-temperature abrasive wear properties of the ZrO2-MoSi2 composite coating were compared with the pure MoSi2 coating at 1100 °C. The XRD results show that there exists mutual transformation between T-MoSi2 and H-MoSi2 phase and part of Mo-rich phases are formed because of oxidization during the spraying processing. The addition of nano-ZrO2 could improve the adhesion between the splats, prevent cracking along the interface between the splats, and purify the boundaries. The ZrO2-MoSi2 composite coating exhibits improved wear resistance compared with the pure MoSi2 coating. The addition of nano-ZrO2 could effectively mitigate the adhesion wear and brittle delamination of the MoSi2 coating.
