中文摘要: 本文对比分析了三种不同石墨化指数 (G.I.) 的六方氮化硼 (hBN) 原料制备的镍基氮化硼复合粉末材料及
封严涂层喷涂过程中 hBN 烧损率。 结果表明， hBN 石墨化指数越低， 所制备涂层材料在热喷涂过程中的损失率
越低， 涂层中氮化硼组分含量越高， 当 hBN 石墨化指数为 1.26 时， 涂层中 hBN 含量为 4.96%， 较粉末减少了
21.14%， 所制备涂层硬度最低， 为 62.0 HR15Y， 该涂层在 815 ℃下可磨耗性能良好。
Abstract:In this paper, the burning loss rate of Nickel based composite powder prepared from three kinds of
hBN raw materials with different graphitization index (G.I.) and the spraying process of abradable coating are
compared and analyzed. The results showed that the lower the G.I. of hBN, the lower the loss rate of abradable
coating material in the thermal spraying process, the higher the content of boron nitride in the coating. When the
graphitization index of hBN was 1.26, the content of hBN in the coating reached 4.96%, which was 21.14% less
than the powder. Meanwhile, the prepared coating exhibited the lowest hardness that was 62.0 HR15Y, and the
coating showed good abrasion performance at 815 ℃ .
