摘要
研究了FGH4097制件在稳定热处理后出现的表面污染变色对零件性能的影响。对FGH4097粉末高温合金模拟件稳定热处理变色后进行组织检查、能谱分析和硬度测试,以及对FGH4097变色盘件化学成分分析、合金试样在空气炉不同热处理温度下的变色情况和热处理1 h后室温拉伸性能检测。结果表明:FGH4097粉末高温合金制零件在稳定处理后的表面污染变色为零件表面被氧化,变色层为一层薄的氧化膜。经过性能试验验证,发现表面污染变色对零件性能的影响不大,能够满足使用要求。
The influence of surface pollution and discoloration after stable heat treatment on the properties of high temperature alloy products prepared from FGH4097 powders was studied.The results showed that the surface contamination discoloration of FGH4097 powder superalloy parts after stable heat treatment was due to the surface oxidation of the parts.The discoloration layer was a thin oxide film.The performance test indicated that the surface pollution and discoloration had little influence on the performance of parts,which could meet the use requirements.
