摘　　要：采用激光表面熔凝工艺，封闭热喷涂纯铝涂层中的孔隙减少了微裂纹。此法不仅提高了涂层质量，而且还使其抗氢渗透性能得到明显的改善。The residual Porosities were eliminated and microcracks were also reduced in thermal sprayed pure aluminum coatings by laser surface remelting and solidification. Therefore, not only was the quality of coatings improvded, but also was the hydrogen \| permeation resistance improved remarkably.
