Description

一种低碳钢镀亚光黑镍抗腐蚀性能试验工艺
技术领域
本发明涉及一种低碳钢镀亚光黑镍抗腐蚀性能试验工艺。
背景技术
盐雾试验是一种主要利用盐雾试验设备所创造的人工模拟盐雾环境条件来考核产品或金属材料耐腐蚀性能的环境试验。盐雾试验标准是对盐雾试验条件，如温度、湿度、氯化钠溶液浓度和PH值等做的明确具体规定，另外还对盐雾试验箱性能提出技术要求。盐雾试验结果的判定方法有：评级判定法、称重判定法、腐蚀物出现判定法、腐蚀数据统计分析法。需要进行盐雾试验的产品主要是一些金属产品，通过检测来考察产品的抗腐蚀性。
工艺上要求，低碳钢表面电镀黑镍后具有以下性能：1、48h盐雾实验合格，即不出现表面腐蚀现象。2、表面无颗粒，即在40倍放大镜下无颗粒，表面为亚光黑。3、镀层结合力大，即黑镍层不掉落。4、镀层均匀度好，即总镀层厚度差为1微米。为了达到以上工艺要求，人们采用以下工艺步骤实现：S1、在低碳钢表面电镀光亮铜；S2、在光亮铜表面电镀半光亮镍；S3、在半光亮镍表面电镀光亮镍；S4、在光亮镍表面电镀黑镍。
该工艺结束后，对得到的产品进行检测，检测结果如下：1、产品表面为光亮黑镍，达不到亚光亮黑镍的效果。2、镀层均匀度差，总镀层厚度差大于5微米，其主要原因是半光亮镍层和光亮镍层的厚度大，造成累积误差大，同时因在电镀镍时，产品的尖角放电形成尖端放电效应，造成产品边缘镀层厚度大于中间镀层厚度。3、盐雾实验合格，因半光亮镍和光亮镍的组合构成电位差，达到耐腐蚀的特点。
发明内容
本发明的目的在于克服现有技术的缺点，提供一种盐雾实验合格、镀层均匀性好、表面为亚光黑镍、工艺简单的低碳钢镀亚光黑镍抗腐蚀性能试验工艺。
本发明的目的通过以下技术方案来实现：一种低碳钢镀亚光黑镍抗腐蚀性能试验工艺，它包括以下步骤：它包括以下步骤：
S1、滚磨：将低碳钢零件放入到滚磨机内，向滚磨机内加入滚磨珠和研磨剂，通过滚磨机在常温下滚磨零件0.5~1h，以除去零件表面上的锈迹；
S2、镀铜：将零件放入到50~60℃的无氰碱铜溶液中，在电流密度为5~10A/dm2下，电镀15~30min，以在零件表面电镀出厚度为1~2微米的铜层；
S3、预镀镍：将零件放入到温度为50~60℃的亚光型氨基磺酸镍中，在电流密度为5~10A/dm2下，电镀15~30min，以在铜层表面电镀出厚度为0.2~0.3微米的亚光镍层；
S4、镀化学镍：将零件放入到盛装有高磷化学镍的槽体中，高磷化学镍的温度为85~95℃，通过高磷化学镍以在亚光镍层的表面形成厚度为8~10微米的化学镍层；
S5、镀化学黑镍：将零件放入到盛装有化学黑镍的槽体中，化学黑镍的温度为40~50℃，通过化学黑镍以在化学镍层的表面形成厚度小于0.2微米的化学黑镍层；
S6、在化学黑镍层的表面上进行无铬钝化处理，从而得到具有亚光黑镍层的零件。
本发明具有以下优点：本发明盐雾实验合格、镀层均匀性好、表面为亚光黑镍、工艺简单。
具体实施方式
下面对本发明做进一步的描述，本发明的保护范围不局限于以下所述：
一种低碳钢镀亚光黑镍抗腐蚀性能试验工艺，它包括以下步骤：它包括以下步骤：它包括以下步骤：
S1、滚磨：将低碳钢零件放入到滚磨机内，向滚磨机内加入滚磨珠和研磨剂，通过滚磨机在常温下滚磨零件0.5~1h，以除去零件表面上的锈迹；
S2、镀铜：将零件放入到50~60℃的无氰碱铜溶液中，在电流密度为5~10A/dm2下，电镀15~30min，以在零件表面电镀出厚度为1~2微米的铜层；
S3、预镀镍：将零件放入到温度为50~60℃的亚光型氨基磺酸镍中，在电流密度为5~10A/dm2下，电镀15~30min，以在铜层表面电镀出厚度为0.2~0.3微米的亚光镍层；
S4、镀化学镍：将零件放入到盛装有高磷化学镍的槽体中，高磷化学镍的温度为85~95℃，通过高磷化学镍以在亚光镍层的表面形成厚度为8~10微米的化学镍层；
S5、镀化学黑镍：将零件放入到盛装有化学黑镍的槽体中，化学黑镍的温度为40~50℃，通过化学黑镍以在化学镍层的表面形成厚度小于0.2微米的化学黑镍层；
S6、在化学黑镍层的表面上进行无铬钝化处理，从而得到具有亚光黑镍层的零件。
对得到亚光黑镍零件进行检测，其检测结果如下：
1、盐雾实验合格，其主要原因如下：a、选用高磷化学镍来形成化学镍层，而高磷化学镍耐48h盐雾实验；b、采用无氰碱铜溶液电镀铜，无氰碱铜溶液使镀层致密度高；c、在最外层的化学黑镍层表面上进行无铬钝化处理，以形成氧化膜，氧化膜具有较高的耐腐蚀性能，且能够防止生成的黑镍发彩，即防止黑镍中夹带的锌被氧化而导致表面出现色彩。
2、镀层均匀度好，其主要原因如下：a、电镀后形成的铜层和亚光镍层分别为1~2微米和0.2~0.3微米，因镀层厚度薄，因而产生的累积误差也就非常小；b、采用滚磨机对零件表面进行滚磨，除去了表面锈迹，避免了镀层与锈迹结合后产生凹凸不平面，确保了镀层厚度的均匀性；c、采用高磷化学镍和化学黑镍来形成黑镍，不使电流，替代了传统采用电镀法来形成黑镍，因此不会形成尖端放电效率，也就不会产生电场，确保了零件边缘镀层厚度与中间区域镀层厚度的一致性。
