摘要
Abstract
Different dipping time and zinc bath chemistry were conducted by a hot dipping process simu-lator in laboratory to study their effect on coating weight and thickness .The results show that ,when the experimental steels were immersed for 2 .5s ,4s ,5 .5s in a Zn-0 .15/0 .29% Al zinc bath ,the coating weight increased a little with the immersion time ,but increased a lot as Al content in the zinc bath increased . When the immersion time was 4 s ,the margin was the largest with 45 g/m2 and 5μm improving for coating weight and thickness ,respectively .The SEM morphology of the coating consisted with the measurements of GDOES (Glow Discharge Optical Emissivity Spectroscopy) ,the coating was thinner and coarser along the binding site with lower Al content ,and when Al content increased ,the coating became thicker and smoother on the binding site .关键词
