摘要:

鎂合金是最有前途的輕質(zhì)結(jié)構(gòu)材料之一，但較差的耐蝕性和耐磨性限制了其在工業(yè)領(lǐng)域的進(jìn)一步應(yīng)用。激光熔覆作為一種表面改性技術(shù)，以其獨特的高效性以及涂層與基體間可形成冶金結(jié)合等優(yōu)點，可有效提升鎂合金表面性能。但鎂合金的低熔點特性使得激光工藝參數(shù)和材料選擇對鎂合金表面性能的改善至關(guān)重要。為此，詳細(xì)討論了激光熔覆工藝參數(shù)（激光功率、掃描速度和波長）對熔覆后涂層組織和性能的影響，同時對目前鎂合金表面激光熔覆的主要材料體系進(jìn)行總結(jié)；綜述了鎂合金表面激光熔覆技術(shù)的發(fā)展和現(xiàn)狀，提出了鎂合金表面激光熔覆面臨的主要問題；對今后鎂合金表面激光熔覆研究的發(fā)展方向進(jìn)行了展望。

Abstract:

Magnesium alloys are one of the most promising lightweight structural materials, but the poor corrosion and wear resistance of magnesium alloys restrict their applications. As a surface modification technology, laser cladding can effectively improve the surface properties of magnesium alloys because of its unique high efficiency and metallurgical bonding of coating and substrate. Due to the characteristics of magnesium alloy, laser cladding process parameters and material selection are of vital importance to improve the surface properties of magnesium alloys. The influence of laser cladding process parameters (laser power, scanning speed and wavelength) is discussed in detail, and the main material systems for laser cladding of magnesium alloys are summarized. In addition, the development and status of laser cladding for magnesium alloys are discussed, and the main problems of laser cladding for magnesium alloys are put forward, the future development is proposed.
