摘要:

以磷酸二氢铝黏结剂与陶瓷骨料（氧化铝，硅酸锆，氧化锆）结合，制备出高温抗氧化耐磨损的金属基陶瓷涂层.对影响涂层耐磨性能的因素进行了研究，实验得到最优的耐磨金属基陶瓷涂层工艺：硅酸锆微粉和骨料添加量分别为陶瓷涂层总质量的21%和35%，无机黏结剂中Al/P比在1.3∶3~1.4∶3之间，骨料粒度中粗颗粒所占质量比为40%.对最佳工艺下的金属基陶瓷涂层进行抗氧化性能研究，涂覆金属基陶瓷涂层的金属的氧化增量比未涂覆的金属的氧化增量降低74%，具有很强的抗氧化性能.

Abstract:

The wear-resistant ceramic coatings with anti-oxidation in high temperature were fabricated using aluminium dihydrogen phosphate and ceramic aggregates alumina (Al2O3), zirconium silicate(ZrSiO4), zirconium oxide(ZrO2). The optimized process is as follows: The ratio of zirconium silicate and aggregates in the total weight of coatings are 21% and 35%, respectively. The value of Al/P ranges from 1.3∶3 to 1.4∶3, and the ratio of the coarse particles in the ceramic aggregates is about 40%.Under this process, the coating has the best wear- resistance. The results from anti-oxidation in high temperature indicated that the increased mass for the coating sample is 74% lower than that for the control,indicating that the ceramic coating has strong performance in anti-oxidation.
