Abstract: | In this paper, 1Cr11Ni2W2MoV steel that is aerial engine blade materials was hot dipped Al-6%Si-4%RE in order to improve its application temperature. According to GB/T13303 - 91 standard, samples with coating and without coating were oxidated at 700℃ from 5 h to 600 h. Two oxidation kinetics curves were drawn in terms of data of tests. The results showed that oxidation resistance of 1Cr11Ni2W2MoV steel hot-dipped Al-6% Si-4%RE is better than one without coating. From SEM and EMPA, the surface of coating formed dense and uninterrupted α-Al2O3, which is the bars of oxidation resistance. In addition, according to one crossing point of the two curves, it was suggested that hot dipped aluminum steel should be annealed before used. |
