摘要

为了提高陶瓷承烧板的高温防粘结性能,采用等离子喷涂技术在刚玉-莫来石陶瓷基体上制备纳米钇稳定氧化锆涂层(n-YSZ)和常规钇稳定氧化锆(r-YSZ)涂层,对涂层进行表面形貌分析及孔隙率测试,采用高温熔滴黏附试验测试涂层的接触角。结果显示:n-YSZ涂层表面形貌更加平整致密且表面孔隙率更低,有利于阻止熔滴的侵入破坏,与BaTiO3熔滴的平均接触角最大且大于90°,可明显改善承烧板的高温粘结损坏问题,延长承烧板的使用寿命。

Abstract

For improving the high-temperature antibonding performance of ceramic load bearing boards, nano yttrium stabilized zirconia (n-YSZ) coatings and conventional yttrium stabilized zirconia (r-YSZ) coatings were prepared on corundum-mullite ceramic basal plate by plasma spraying technology. In addition, the surface morphology analysis and porosity test of the coating were conducted, and the high-temperature droplet adhesion test was used to evaluate the contact angle of the coating. Results showed that the surface morphology of n-YSZ coating was smoother and denser, and the surface porosity was lower, which was beneficial to preventing the invasion and damage of molten droplets. Moreover, The average contact angle between n-YSZ coating and BaTiO3 droplet was the highest and greater than 90 °, which could significantly improve the high-temperature bonding damage problem of load bearing boards, and extend the service life of load bearing boards.

Key words： load bearing boards; n-YSZ coatings; r-YSZ coatings; plasma spraying; high-temperature antibonding
