Description
技术领域：
本发明涉及一种蜂窝式密封件用材料。
背景技术：
进入21世纪，世界各国争先发展能源动力行业，顶尖技术是航空航天航海技术。其中最关键的是航空发动机、航天发动机及船舶动力。密封是以上科技发展的重要环节，也可以说是最关键技术。
蜂窝式密封件主要用于汽轮机、燃机、航空发动机、空压机等转速在1500rpm以上的转子与定子间的密封。
现在汽轮机、燃机等所使用的蜂窝式密封的材质为哈氏耐高温合金，合金牌号GH536，使用温度在900℃以下，高温后蜂窝形状容易变形。
发明内容：
本发明所要解决的技术问题是提供一种耐高温，强度高，不易变形的蜂窝式密封件材料。
上述目的是这样实现的：本材料是在耐高温钢表面刷镀陶瓷合金得到的；
所述的耐高温钢为高镍基铬、钴合金，其成分及质量百分比为：Cr占19.5%，Ni占18%，Mo占4.25%，Co占13.5%，Ti 占3.05%，C占0.04%，Mn占0.1%，Si占0.55%，B占0.01%，Cu ≤0.1%，其余为铁。所述的耐高温钢用高温（1800℃以上）真空转炉冶炼而成。
所述的镀陶瓷合金的各成分及质量百分比为：Al2O3占22%,SiO2占24%,B2O3占14%，其余为镍和钴及稀有元素。
所述的稀有元素为钛Ti、铍Be、钼Mo，稀有金属质量比为；钛：铍：钼=6：2：2。
镍和钴及稀有元素之间的质量比是7：2：1。
在高镍基铬、钴合金上均匀涂抹陶瓷合金粉后用真空炉烧制高温烧制，温度大约是1100℃-1500℃。
本发明的优点是：由于镀陶瓷合金中含有钴和镍，钴能显著提高特殊用途钢的热强性和高温硬度；提高马氏体的高温稳定性，使其具有超强韧性。镍能细化和增多珠光体，提高钢的强度，并不改变钢的塑性；提高钢回火稳定性，增加调质性能；提高钢的耐磨及疲劳性能；减少钢的碳含量可，增加塑性提高加工性能。微量元素对提高产品质量起很大作用。本材料可以耐高温超过1000℃，并且不易变形。
