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。
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.
