    摘要:

    對(duì)電子粉床熔合（EPBF）制造的Ti6Al4V合金分別進(jìn)行1 h的600 ℃去應(yīng)力退火、800 ℃退火和920 ℃固溶熱處理，然后對(duì)熱處理前后的試樣進(jìn)行摩擦磨損實(shí)驗(yàn)，分析比較摩擦磨損性能和機(jī)理。結(jié)果表明，600 ℃去應(yīng)力退火+1 h熱處理后的試樣耐磨性能最佳，磨損質(zhì)量減少了44%。800 ℃退火+1 h熱處理后的試樣減摩性能最好，摩擦系數(shù)減小了14%。本研究提供了一種簡(jiǎn)單的熱處理方式，提高了EPBF制造Ti6Al4V合金的減摩耐磨性能。

    Abstract:

    Ti6Al4V alloy manufactured by electron powder bed fusion (EPBF) was separately heat-treated by stress-relief annealing at 600 °C, annealing at 800 °C, and solid solution at 920 °C for 1 h. Then, the friction and wear tests were conducted on the samples before and after heat treatment to analyze the properties and mechanism of friction and wear behavior. Results show that the sample annealed at 600 °C for 1 h has the optimal wear resistance, and the wear mass loss reduces by 44%. The sample annealed at 800 °C for 1 h possesses the optimal anti-friction performance, and the coefficient of friction reduces by 14%. This research provides a simple heat treatment method to improve the friction and wear resistance of Ti6Al4V alloy manufactured by EPBF.
