中文摘要:
      镁合金作为最轻的金属结构材料,具有密度低、比强度高、弹性模量大等优势,在航天航空、汽车工业、电子通讯等领域广泛应用,但其化学性质非常活泼,在常温下很容易发生腐蚀,严重限制了其进一步推广应用。化学镀镍具有镀层致密、环境友好等优点,可有效提高镁合金的耐蚀性和耐磨性,但与普通基体相比,镁合金属于难镀金属,化学镀镍前既要去除基体表面原有的疏松多孔的氧化膜,又要生成具有保护和催化作用的新膜层,因此前处理工艺是影响镀层质量及镁合金防腐性能提高的关键因素。以化学镀镍前处理工艺为研究内容,介绍了镁合金化学镀镍前处理工艺的国内外研究现状,从除油、酸洗、活化、浸锌法、预镀层和化学转化膜等方面进行了文献综述和分析,指出相应工艺的优缺点,并探讨了研发方向。根据前处理技术的机理和不同牌号镁合金的特点,研发工艺简单、镀层性能优良、可控性强、环境友好、通用性强的低成本工艺,将是镁合金化学镀镍前处理的研究方向和发展趋势。
英文摘要:
      Magnesium alloy is the lightest metal structural material, which has many advantages, such as low density, high specific strength and high elastic modulus. And it can be widely used in the aerospace, automotive industry, electronic communication, and other fields. However, its chemical properties are very lively , and it is easy to corrode at room temperature, which seriously limits its further application. The method of electroless nickel coating showed a lot of features including compact, environment friendly and other advantages, which has become the effective method to improve the corrosion resistance of magnesium alloy and abrasion resistance, but compared with the ordinary matrix, magnesium alloy belongs to metal plating, it may be necessary to remove the original loose long-short oxide film in the substrate surface for electroless nickel plating, and to generate a new film with protection and catalysis. The pretreatment process is a key factor affecting the coating quality and improve the corrosion resistance of magnesium alloy. The results based on process of electroless nickel plating as the research content, introduces the research status of electroless nickel plating on magnesium alloy pretreatment technology at home and abroad, from degreasing and pickling activation, zinc dipping method, pre coating and chemical conversion film and other aspects of the literature review and analysis, which pointes out the advantages and disadvantages of the corresponding process and discusses the research direction. According to the characteristics of R & D process mechanism of pretreatment technology and different grades of alloy magnesium coating, the technology of simple, excellent performance, strong controllability, environmental friendly, strong versatility and low cost process will be the research direction and development trend of electroless nickel plating on magnesium alloy before treatment.
