【摘要】

：

热障涂层的失效对于热障涂层系统在工业上的广泛应用是一个关键问题,引发热障涂层失效的因素有很多,热膨胀系数不匹配、金属基底的粗糙度、陶瓷层和粘结层内表面的氧化和腐蚀、陶瓷层和粘结层的烧结及化学反应、陶瓷涂层的相变等.在热循环过程中,伴随着相变所产生的体积膨胀而引发的应力是一个决定TBC寿命的关键因素.因此本研究的重点是采用稀土荧光这种新型无损检测技术检测热循环过程中的8YSZ陶瓷顶层的相变问题.

超音速火焰喷涂TiB2-40Co金属陶瓷涂层抗热震性能研究

通过超音速火焰喷涂技术在不同氧气流量条件下将3种TiB2-40Co金属陶瓷涂层喷涂在Q235钢基体表面,研究3种涂层在600℃不同热震循环次数和800℃条件下的抗热震性能.通过扫描电子显微镜和X射线衍射仪对3种涂层在不同条件下热震后的表面和截面形貌及物相结构进行分析.研究结果表明,在600℃热震条件下,随着氧气流量的增加,涂层的抗热震性能降低,并在热震次数为150次,氧气流量为482L/min时,
