| Abstract: | 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. |
