一、前言1976年,我们研制的硅化物涂层Si-15Cr-10Ti-10Zr(简称Si-15Cr)涂层,与同类涂层比较,具有熔烧温度低、抗氧化、抗热震性能好、加涂工艺简单、涂层表面光洁、可局部修补等优点。经实验室检验和多次试车考核,认为是一个有实用价值的铌合金高温抗氧化涂层,但涂层的熔烧温度和保温时间对涂层及基材的主要性能均有不同程度的影响。本文试图通过对Si-15Cr/C-103 涂层的金相观察、“电子探针”分析、“X光衍射”结构分析的结
First, the foreword In 1976, we developed the silicide coating Si-15Cr-10Ti-10Zr (referred to as Si-15Cr) coating, compared with similar coatings, with a low melting temperature, oxidation resistance, thermal shock resistance, Add coating process is simple, the coating surface smooth, partial repair and other advantages. The laboratory test and several test cars, considered to be a practical high-temperature oxidation of niobium alloy coating, but the coating of the sintering temperature and holding time on the coating and the main properties of the substrate have varying degrees of impact . This paper attempts to Si-15Cr / C-103 coatings by metallographic observation, “electron probe” analysis, “X-ray diffraction” structure analysis of the junction
