| 中文摘要: |
| 为了研究一种中温黑色磷化工艺，借助金相显微镜和扫描电镜对磷化膜的结构和形貌进行表征。黑色磷化膜表调后的厚度为6μm，其厚度为表调前传统磷化膜的1/3左右。通过表调也可使磷化膜均匀、致密，耐蚀性得到明显提高。硫酸铜点滴腐蚀时间是国家标准的4倍，氯化钠浸渍达72h。结果得到了一种成本低廉、无沉渣、无毒、膜黑的工业生产型磷化液。此工艺可以满足工业化批量生产要求。 |
| 英文摘要: |
| A black phosphating process at mid-temperaturem was discussed. The morphology and structure of the phosphating film were analyzed by means of the gold mutually microscope and SEM. The thickness of the black phosphating coating can reach t0 6μm by surface conditioning process, which is nearly one third the thickness of the traditional phosphating coating without surface conditioning process. And it shows that the compact and continuity, corrosion resistance of the film will be improved obviously by surface conditioning process. The corrossion time in copper sulfate spot test is four times as high as national standard and the time for sodium chloride bath test is up t0 72h. It was found out that the obtained black phosphating film is low cost, no-sedimented, nonpoisonous, and can make the production of phosphating bath industrialized. The technics can meet the requirements of the industrialized mass production. |
