Ti-Cr-Si硅化物涂层结构及裂纹扩展

Microstructure and Crack Propagation of Ti-Cr-Si Silicide Coatings on the Niobium Alloy C-103

分析研究了 C- 10 3铌合金改性 Ti- Cr- Si保护涂层氧化过程中结构的变化以及裂纹扩展过程。结果表明 ,涂层表面玻璃态氧化物性质。

Microstructural variation and crack propagation of modified Ti Cr Si silicide coatings on the niobium alloy C 103 during oxidation at high temperatures in air have been studied. The results show that the crack propagation behavior is commonly determined by superficial glass phase, the silicon content of the body coating, and the growth and mechanical properties of low valent silicide.
