金属基高温耐磨陶瓷涂层的研制及耐磨性能的影响因素

Study of Matrix-ceramic Wear-resisting Coating on High Temperature and The Affecting Factor of the Wear-resisting

本课题研制了一种用陶瓷骨料与自制无机胶粘剂为原料 ,具有高温耐磨性能的陶瓷涂层配方 ,并探讨了影响涂层耐磨性能的因素。发现 :当磷酸铝胶粘剂中Al2 O3与P2 O5 之比为1 3∶3～ 1 4∶3,涂层中的骨料与胶粘剂的配比为 1 7∶1 ,且骨料中粗颗粒含量为 40～ 5 0 %时 。

s:In this paper,a kind of prescription of ceramic coating with wear resisting on high temperature was prepared by using ceramic aggregates and organic bond.We also discussed the factors of affecting the wear resisting properties of ceramic coating.We found that the wear resisting is best when Al 2O 3/P 2O 5 is 1.3∶3～1.4∶3;the ratio of aggregates and organic bond in the coating is 1.7∶1;and the content of big grains is 40～50%
