摘　　要：以酒石酸钾钠为还原剂,在304不锈钢表面进行了化学镀银,研究了化学镀银液的配方组分、镀液pH及温度等工艺参数对化学镀银速率的影响。较理想的化学镀银工艺为:硝酸银20g/L,氨水80mL/L,酒石酸钾钠100g/L,pH12.5,温度20°C。在该工艺条件下得到的镀银层均匀、致密,结合力好。Electroless silver plating on the surface of 304 stainless steel was carried out with potassium sodium tartrate as reducing agent. The effects of bath composition, pH and temperature on plating rate were studied. The ideal process conditions were determined as follows： AgNO3 20 g/L, NH3·H2O 80 mL/L, KNaCaH4O6·4H2O 100 g/L, pH 12.5 and temperature 20 ℃. Under the given conditions, the silver deposit is uniform, compact and well-adhered.
