Abstract本文利用离心铸造的方法,在金属型中浇铸了T 湛8%A轼%Cr-2%Nb合金汽车排气阀,通过SEM、XRD和EMPA等分析手段。对排气阀坯件的表面层结组织形态、成分分布和力学性能等特征进行了检测,并将热等静压(HIP)处理后的排气阀安装到483Q型柴油发动机上进行了台架试验,结果表明,金属型离心浇铸Ti-Al基合金排气阀,在保证阀体成分均匀性的同时,可在一定程度上细化铸件的显微组织,HIP处理后排气阀的平均力学性能为:σb=670MPa,σ0.2=527.5MPa和δ=3%,进一步的台架测试结果表明,热电厂气阀在测试过程中表现出了优异的密封性和耐磨性,完全满足发动机的性能要求。
