摘要:本发明公开了一种高温耐磨损抗氧化涂层的制备方法,先对基底试样进行喷砂处理,然后采用等离子喷涂法对试样进行喷涂处理,最后经高温真空热处理制备成MCrAlY涂层。通过对涂层进行真空热处理,有效降低涂层中的裂纹和气孔等缺陷,涂层的结合强度明显升高,1100℃热处理后,涂层的气孔率降低为0.86%,结合强度升高为62.1Mpa,900℃高温下具有优异的耐磨性和抗氧化性能,综合性能较好。

Abstract: The invention discloses a preparation method of a high-temperature anti-abrasion antioxidation coating. Firstly, a substrate specimen is subjected to sand blasting treatment; then, the specimen is subjected to spray coating treatment by a plasma spray coating method; finally, a MCrAlY coating is prepared through high-temperature vacuum heat treatment. The coating is subjected to vacuum heat treatment, so that the defects such as cracks and pores in the coating are effectively reduced; the bonding intensity of the coating is obviously improved; after 1100 DEG C heat treatment, the porosity of the coating is reduced to 0.86 percent; the bonding intensity is improved to 62.1Mpa; at high temperature of 900 DEG C, excellent abrasion performance and antioxidation performance are realized; the comprehensive performance is good.
