温度测量和等离子喷涂热障涂层的粘接特性--外文翻译.rar

Metal-ceramic coatings have been widely used for industrial applications, mainly in the gas turbine and
diesel engine industries as thermal barrier coatings (TBCs). Conventional thermal barrier coatings consist
of a metallic bond coat and an insulating ceramic topcoat. Temperatures and temperature gradients
in the coating during plasma spraying play an important role on the final coating quality, especially the
temperature of the particles just hitting the substrate surface. In this work, metal-ceramic coatings were
applied on nickel-superalloy substrates. The temperatures of both the coating surface and substrate were
measured during spraying. The adhesion of the coatings was determined using ASTM C 633 and correlated
with the measured temperatures. Optical pyrometry and thermocouples were used to measure the
interfacial and substrate temperatures, respectively. Temperature was shown to have a significant influence
where lower interfacial temperatures were found to result in lower adhesion values.

金属陶瓷涂层已被广泛用于工业应用，主要是在燃气轮机和柴油发动机行业的热障涂层（TBCs).传统的热障涂层是由一个金属粘结层和绝缘陶瓷面漆构成.温度和在涂层的温度梯度在最终涂层质量上在等离子喷涂上发挥重要作用.特别是对粒子的温度只是命中衬底表面,在这项工作中，金属陶瓷涂料适用于镍合金基板.在涂层表面和衬底之间的温度喷涂间测量.粘附涂层决定使用美国ASTM c 633和与实测的温度相关.光学和热电偶分别用来衡量界面和衬底温度.温度显示在被发现结果在较低的粘附的价值观有重大影响的情况下降低界面的温度.
