表面涂层方法可以提高金属的耐热温度,但难以做到涂层与基体的良好结合。Ti-Si系涂层在一些成分范围内有一些反常的耐热性,因此有必要对其形成特征、成分及其耐热性进行研究。利用X射线衍射研究了粉末扩散和涂层的相组成,通过微探针和扫描电镜研究了涂层的结构和成分。用钛硅化
Surface coating method can improve the heat-resistant temperature of the metal, but it is difficult to achieve a good combination of the coating and the substrate. Ti-Si-based coatings have some abnormal heat resistance in some composition ranges, so it is necessary to study their formation characteristics, composition and heat resistance. The phase composition of powder diffusion and coating was studied by X-ray diffraction. The structure and composition of the coating were studied by microprobe and scanning electron microscope.
