摘　　要：针对熔锌锅内加热器套管材料问题,根据近些年国内外对耐液锌腐蚀材料的研究成果,可将耐锌蚀材料分为采用自身耐蚀的材料或利用金属表面处理技术提高耐蚀性两大类。由于熔融锌几乎对所有的金属都能产生强烈的腐蚀,所以整体金属材料的耐熔融锌腐蚀性较差;无机材料和粉末冶金材料虽然都具有较强的耐熔融锌腐蚀性,但是其脆性大,制备成本高昂,在实际生产中的应用受到限制。因此采用金属表面处理方法提高耐熔融锌腐蚀性将成为今后的研究重点。诸如热喷涂、渗硼法、表面涂覆等表面处理技术,均可以在保持原有金属特性的基础上提高材料表面的耐锌蚀性。最后指出了今后耐熔融锌腐蚀材料的研究发展方向。According to the recent research at home and abroad, corrosion resistant materials for inner heater in molten zinc could be divided into two kinds i. e, self corrosion resistantmaterials and metallic materials modified by surface treatments. The corrosion resistance of metal materials in molten zinc is not good, and inorganic materials and sintered powder metal products have a strong corrosion resistance but they are brittle and have a high cost, so that the metal surface treatment method will attract more and more interest in the future. Surface treatment techniques, such as thermal spraying, boronizing and surface coating, are able to enhance the corrosion resistance in molten zinc, and thus could maintain the original characteristics of the metal substrate. The research trend of corrosion resistant materials in molten zinc in the future is pointed out.
