- 摘要:
- 选取钢结构连接使用的异形螺栓作为研究对象进行锰系磷化，研究了磷化液中硝酸锰质量浓度、磷酸二氢锰质量浓度以及温度、磷化时间对锰系磷化膜的宏观形貌及耐硫酸铜点滴时间的影响。结果表明：随着硝酸锰质量浓度和磷酸二氢锰质量浓度增加、温度升高及磷化时间延长，锰系磷化膜表面由较粗糙疏松趋于平整致密，然后再变为较粗糙疏松，色泽随之变化，耐硫酸铜点滴时间呈现先延长后缩短的趋势。最佳的硝酸锰浓度为20 g/L、磷酸二氢锰浓度为45 g/L、温度为90 ℃、磷化时间为20 min，由此获得的锰系磷化膜呈纯黑色，表面平整致密，晶粒之间衔接紧密，主要含有Mn、P和O三种元素，其耐硫酸铜点滴时间达448 s。在相同的中性盐雾实验条件下，未磷化螺栓发生了严重的全面腐蚀，而锰系磷化后螺栓的腐蚀程度较轻，耐蚀性显著提高。
- Abstract:
- Manganese phosphating was carried out using a special shaped bolt used for steel structure connection as the research object， and the influence of the mass concentration of manganese nitrate and manganese dihydrogen phosphate in the phosphating solution， temperature and phosphating time on the macro-morphology and the time against corrosion of copper sulfate dropping was studied. The results showed that as the mass concentration of manganese nitrate and manganese dihydrogen phosphate increased， the temperature raised and phosphating time prolonged， the surface of manganese phosphating film changed from rough and loose to flat and compact， and then to rough and loose. The colour and lustre was changed， and the time against corrosion of copper sulfate dropping initially prolonged and then shortened. The optimal mass concentration of manganese nitrate was 20 g/L， mass concentration of manganese dihydrogen phosphate was 45 g/L， temperature was 90 ℃ and phosphating time was 20 min， and the prepared manganese phosphating film was pure black， mainly composed of Mn， P and O elements， its surface was flat and compact， the cohesion between the grains was tight， and the time against corrosion of copper sulfate dropping reached 448 s. Under the same neutral salt spray test conditions， the bolt without phosphating was general corrosion and its corrosion degree was serious， however the corrosion degree of the bolt after phosphating was light， and its corrosion resistance was significantly improved
