摘　　要：针对碳钢材料采用某常温锌系磷化工艺进行磷化加工的优化问题,文章分析了磷化时间对磷化膜形貌(表面形貌和横截面形貌),磷化膜化学状态(元素含量和分布,结晶情况和亲水性),耐腐蚀特性(盐水浸泡实验和Tafel曲线实验)的影响。发现15~20 min该工艺磷化膜生长速度较快,而20~30 min磷化膜生长速度显著下降。该研究为碳钢材料在该工艺中磷化时间的选择提供了参考。The phosphating time is a criical parameter for the normal-temperature phosphating process.The inluence ofphosphating time on the morphology(surace and cross-section),chemical composition,the distribution of major elements,thecorrosion resistance of the as-synthesized phosphate film were sludied.It was found that the phosphate film grows faster relalively inthe period between 15-20 min rather than that in the period between 20-30 min.This work provides evidence for the selection ofphosphating time in the design of phosphate film.
