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。
The effect of BN content on the sintering properties of nickel-based abradable sealing materials was studied. The sintering process of Ni-Cr and Ni-Cr / BN was analyzed and the sintering process model was established. The results show that the addition of BN hinders the sintering of the powder particles and leads to the volume expansion and the decrease of density after sintering.
