室温装饰镀铬实践

Practice in room-temperature and decorative chromium plating

结合多年镀铬生产的实际情况，提出了一种室温装饰镀铬工艺。几年生产实践表明，该工艺与一般镀铬工艺及其它镀铬工艺比较起来，质量稳定，维护简单，且节约了成本。列出了该工艺与标准镀铬、某高速装饰镀铬等3种工艺的工艺规范并进行了说明。对该工艺的镀液维护及注意事项、一般故障及排除、应用情况进行了介绍。测试了镀液的分散能力及覆盖能力。最终确定电流密度范围为10～20A／dm^2。该工艺适合各种装饰镀铬件。

A room-temperature and decorative chromium plating process was proposed in combination with many years of practical experience in chromium plating production. Several years of production practice show that the process has advantages of stable quality, easy maintenance, and lower cost compared with common and other chromium plating processes. The process specifications of the given process, standard chromium plating and one high-speed decorative chromium plating processes were listed and explained. The bath maintenance, notices, common trouble-shootings and application situations of the process were introduced. The throwing power and covering power of the bath were measured, and the current density range was finally obtained to be 10-20 A/dm^2. The process is suitable for all kinds of parts needing decorative chromium plating.
