BN对镍基可磨耗密封材料烧结性能的影响

Effect of BN on Sintering Properties of Ni-based Abradable Seal Alloy

摘要:

研究了BN含量对镍基可磨耗密封材料烧结性能的影响，分析了Ni-Cr和Ni-Cr／BN的烧结过程，并建立了烧结过程模型。结果表明：加入BN阻碍了粉末颗粒之间的烧结，引起材料烧结后体积膨胀和密度下降。

Abstract:

The effect of BN content on sintering properties of Ni-based abradable seal alloy was investigated. The sintering process and model with BN and without BN were studied. To establish model to research the process of Ni-Cr/BN sintering expansion. BN powders hinder sintering between powders, and the sintering expansion and the density falling are discovered.
