摘要/Abstract

摘要： 采用低氧压高温快速熔结技术在钛合金表面制备AlCr熔结涂层,通过对涂层形貌及涂层断面的组织结构进行观察、分析,研究了熔结时间等工艺参数对熔结涂层的形成及AlCr涂层对Ti6Al4V合金在600℃(873K)空气中循环氧化行为的影响。结果表明:合理控制熔结时间可控制互溶区的宽度,大大增强涂层与基体的结合强度和涂层的循环氧化抗力,在本试验条件下,使合金的抗循环氧化能力提高了近300倍。

关键词: 金属材料, Ti6Al4V合金, 低氧压熔结AlCr涂层, 高温氧化

Abstract: The low oxygen pressure self-fused Al-Cr coatings were made on the surface of the samples from the Ti-6Al-4V alloy. The effects of processing parameters such as fusing time, etc, on the formation of the coating and the effects of the Al-Cr coating on the cyclic oxidation behavior of the alloy in the air at the temperature of 873 K were investigated by observing and analyzing the surface morphology and the cross-section structures of the coating. The results show that the thickness of the inter-diffusion zone can be controlled by the fusing time, and processing for an appropriate fusing time may greatly improve the adherence of the coating to the substrate and enhance the cyclic oxidation resistance of the coating. The oxidation resistance of the coated sample is almost 300 times higher than that of the uncoated sample.

Key words: metallic material, Ti-6Al-4V alloy, low oxygen pressure self-fused Al-Cr coating, high-temperature oxidation
