摘要:
采用固体渗剂包埋渗法对Ti-6Al-4V钛合金进行硼-稀土共渗处理,并利用超声振动空蚀机研究分析试样在去离子水中的空蚀性能。结果表明,硼-稀土共渗在Ti-6Al-4V合金表面获得均匀致密的表面渗层。表面渗层具有很高的显微硬度,与基体冶金结合,其主要由TiB2、TiB化合物层和B原子固溶于α-Ti的扩散层构成。稀土元素La的添加,提高渗硼效率,使试样表面渗层厚度增加,显微硬度显著提高,材料的抗空蚀性能得到显著改善。
Abstract:
Ti-6Al-4V alloy was treated by using pack rare earth-boronizing. The cavitation erosion resistance of the treated specimens was studied in deionized water by using ultrasonic vibration cavitation equipment. Results show that a uniform and dense surface layer was obtained on the surface of the treated Ti-6Al-4V alloy specimens. The surface layer shows high microhardness and good metallurgical bonding consisted of a compound layer (TiB2 and TiB phases) and a diffusion layer (α-Ti (B)). The rare earth element could improve boronizing efficiency, thus increasing thickness of the surface layer, surface microhardness and cavitation resistance of the treated Ti-6Al-4V alloy specimens.
