摘要
研究了Ａ_３钢采用熔剂法热浸铝时，温度、时间对浸铝层生长规律的影响。结果表明，表面层的生长过程具有“凝固溶解期”→“扩散增厚期”→“过渡平衡期”三个不同阶段，过渡层的生长符合指数增长规律。根据生长规律曲线提出了耐蚀、耐热用浸铝钢的选择规范。
Hot-dip aluminizing A_3 steel has been investigated by optical microscopy, the investigation concerned with the affecting of temperature and time to the growth of hot-dip aluminizing coating. After hot-dip by flux method, it showed that the growth process of surface layer experiences three different periods, i. e. 'solidification-disolution period '→'diffusion-accretion period'→'transition-equlibrium period', the growth of transition layer coincides with exponent law. In addition, the choice criterion of the hot-dip aluminizing of the steel used in environment of corrosion and oxidation has been proposed in the light of the growth law.
