摘要:
本发明提供一种高温材料输送用构件。该高温材料输送用构件的耐积层性、耐氧化性及耐热裂纹性优良。该高温材料输送用构件在母材表面形成有被膜,其中,被膜是采用由Co基合金粉末和Cr碳化物的粉末构成的混合粉末,利用等离子粉体堆焊法形成的复合被膜,该Co基合金粉末按质量%计含有0.03%~0.6%的C、0.2%~3%的Si、22%~35%的Cr及大于50%的Co。该高温材料输送用构件特别是在1100℃以上的气体气氛下具有优良的耐积层性。
摘要(英):
A high-temperature material transferring member including a coating film formed on a surface of base metal, wherein the coating film is a composite coating film using a mixed powder made up of: a Co-based alloy powder containing, in mass%, 0.03 to 0.6% of C, 0.2 to 3% of Si, 22 to 35% of Cr, and more than 50% of Co; and a Cr carbide powder, the composite coating film is formed by the plasma powder overlaying process. The high-temperature material transferring member has excellent build-up resistance particularly in a gas atmosphere of 1100°C or more. The high-temperature material transferring member has excellent in build-up resistance, oxidation resistance, and heat cracking resistance.
