摘　　要：开发了Trich-9289硫酸盐体系三价铬电镀装饰铬的新工艺。该工艺电流效率高,沉积速率达到0.072μm/min,并且不随电镀时间延长而改变。镀液性能稳定,操作简单,便于维护。铬镀层光滑,无裂纹或孔隙,结合力强,厚度在0.3μm以上,中性盐雾试验72h不变色,恒定湿热试验、冷热冲击试验、人造汗液测试及抗化学污染测试均合格。A novel Trich-9289 process for decorative trivalent chromium plating in sulfate system was developed. The current efficiency of the process is high and the deposition rate reaches 0.072 μm/min, invariable with prolonged plating time. The plating bath has advantages of high stability, simple operation, and easy maintenance. The chromium coating is smooth, crack and pore-free, and well-adhered, with a thickness above 0.3 μm; it does not tarnish after neutral salt spray test for 72 h, and can pass the steady-state damp heat test, cold-heat shock test, artificial sweat test, and chemical contamination test.
