【摘要】 论述了镁合金表面处理,包括化学表面转化处理、机械表面硬化处理、强束流表面改性3方面的研究现状,着重叙述了铬化、磷化处理、阳极氧化、微弧氧化等表面处理工艺。同时,还论述了机械表面硬化处理的表面喷丸强化和滚压强化。强束流表面改性代表现代先进表面改性技术,包括离子束、激光束、电子束表面改性,国外研究较多,而国内研究相对较少,应该引起足够的重视。更多还原

【Abstract】 A review was made on the progress of surface treatment for magnesium alloys, which including chemical converting coating, mechanical surface hardening treatment and high\|intensity beams surface modification. The chemical surface treatment was focused on the chromate and phosphate coatings, anodic oxidation and micro\|arc oxidation. The mechanical surface treatment was concentrated on shot peening and rolling strengthening. The high beam surface modification represented the modern advanced surface treatment technology, including ion, laser and electron beam surface modification. The technique had become one of oversea research hotspots, but was relatively few in our country, so it should arouse our attentions.更多还原
