中文摘要:
      根据近些年国内外耐锌腐蚀的研究成果,将耐锌腐蚀方法分为两大类:自身耐锌腐蚀材料和表面改性处理。自身耐锌腐蚀材料主要集中在 Fe-Cr-Mn、Fe-B、TiAlNb 等材料上,表面处理主要集中在 WC-Co、 MoB-CoCr、陶瓷等涂层上。两种方法都获得一定的研究成果,但也有一些不足。自身耐锌腐蚀材料的耐熔锌腐蚀虽有改善,但在液锌中也只是延缓了腐蚀速度,最终仍然会腐蚀失效。表面涂层耐蚀性相对较好,但是在锌液中仍然会发生裂纹腐蚀,并且涂层和基体之间的物理匹配性较差,脆性较大,工件的轻微碰撞很容易造成涂层的脱落,加速工件的腐蚀,不宜用于实际生产。充分利用陶瓷耐腐蚀、耐高温、硬度高的优点,以及金属室温强度好、延展性好的优点,开发陶瓷金属复合涂层,可能会成为下一步沉没辊基础件熔融锌液腐蚀研究的主要方向。
英文摘要:
      According to the research achievements about corrosion in molten zinc at home and abroad in recent years, corrosion resistant method can be divided into two categories: corrosion resistant material and surface modification. Corrosion resistant materials are mainly concentrated in Fe-Cr-Mn, Fe-B and TiAlNb, etc., while surface treatment is mainly concentrated in WC- Co, MoB-CoCr, and ceramic coating. Two research methods have certain research results, but there are also some shortcomings. Although corrosion resistant of materials to molten zinc is improved, only the corrosion speed is delayed for the corrosion property in the liquid zinc and eventually the corrosion failure still occurs. Corrosion resistance of surface coating is relatively good, but crack still occurs in liquid zinc. Physical fit between coating and matrix is poorer, and brittleness is larger. Slight collision between parts causes coating to fall off easily and accelerates the corrosion of materials, so the coating should not be used in practical production. Ceramic-metal composite coatings can be developed by making full use of the advantages of corrosion resistance, high temperature resistance and high hardness in ceramics and good room temperature strength and fair ductility of metals and it may become the next the main direction of research about corrosion of sink roll in molten liquid zinc.
