| titleOfInvention | A kind of method of silver-plated Darkening process |
| abstract | The invention provides a kind of method of silver-plated Darkening process, belongs to plating and field of surface treatment, and silver coating chemical property can be made stable, it is anticorrosive, plating piece or sample chromatism measurement after silver-plated melanism is more pitch-black, ensures that large area is uniform, increases the stability and service life of plating piece.The present invention comprises the following steps：Base material is pre-processed first；Then electrosilvering is carried out to base material after the pretreatment；Finally to it is described it is silver-plated after plating piece carry out Darkening process, wherein blackened solution includes main black agent, auxiliary black agent, surfactant, melanism additive and pH adjusting agent, and blackened solution pH value is 2.0 ~ 8.0；Negative electrode uses stainless steel or titanium basket inert material when operating condition is melanism, anode for it is described it is silver-plated after plating piece, electroplating power supply is constant current mode, and current density is 0.2 A/dm 2 ~2.0 A/dm 2 , the melanism time is the min of 0.5 min ~ 5；Operating temperature is 30 DEG C ~ 60 DEG C. |
