    摘要:

    單晶葉片激光修復(fù)技術(shù)為航空領(lǐng)域節(jié)約了大量成本，該技術(shù)以增材制造工藝為基礎(chǔ)，以期在單晶基底上通過定向凝固生長出理想的單晶結(jié)構(gòu)。目前，主流的單晶葉片修復(fù)技術(shù)包括以下兩類：定向能量沉積技術(shù)（Directed Energy Deposition，DED）、粉末床熔融技術(shù)（Powder Bed Fusion，PBF）。本文綜述了兩種主要修復(fù)技術(shù)的研究進(jìn)展，總結(jié)了修復(fù)過程中工藝參數(shù)的影響及單晶生長的機(jī)理，闡明了單晶修復(fù)技術(shù)在航空領(lǐng)域的應(yīng)用潛力。此外，本文還討論了單晶葉片修復(fù)目前面臨的主要挑戰(zhàn)，并對其未來發(fā)展趨勢進(jìn)行展望。

    Abstract:

    The single crystal blade laser repair technology reduced considerable cost in the aviation field. This technology is based on the additive manufacturing process, in order to grow an ideal single crystal structure through directional solidification on the single crystal substrate. At present, the mainstream single crystal blade repair technology includes the following two categories: Directed Energy Deposition (DED), Powder Bed Fusion (PBF). In this paper, the research progress of two main repair technologies is reviewed, the influence of process parameters and the mechanism of single crystal growth in the repair process are summarized, and the application potential of single crystal repair technology in the aerospace field is clarified. In addition, this paper also discusses the main challenges currently faced by single crystal blade repair then looks forward to its future development trend.
