摘　　要：首先介绍了目前现有的等离子射流检测方法,着重综述了PS-PVD等离子射流非接触式检测手段—光谱诊断(OES)技术及其计算方法,以及通过此手段检测H_(2)对射流特性的影响。其次,从H_(2)对涂层物相、组织结构相和热导率的影响出发,介绍了现阶段国内外H_(2)工艺参数对于涂层微观形貌结构影响的研究现状。基于此,通过涂层抗粒子冲蚀能力和抗钙镁铝硅酸盐(CMAS)腐蚀能力对涂层的力学性能和热防护性能差异进行了总结与评价。最后展望了今后PS-PVD制备热障涂层技术兼顾力学性能与热防护性能的发展可能性。In this paper,the existing plasma jet detection methods are introduced firstly,and the non-contact detection method of PS-PVD jet that spectral diagnostic technique and its calculation method are emphatically reviewed.Secondly,based on the influence of H_(2) on the phase,microstructure phase and thermal conductivity of the coating,the research status of the influence of H_(2) process parameters on the microstructure of the coating at home and abroad is introduced,and the differences between mechanical properties and thermal protection properties of the coating are summarized and evaluated from the particle erosion resistance and the corrosion resistance of the coating to calcium magnesium aluminum silicate(CMAS).Finally,the possibility of combining mechanical properties with thermal protection properties of PS-PVD thermal barrier coatings in the future is prospected.
