| titleOfInvention | Surface treatment method to improve the corrosion resistance of silver plated products |
| abstract | The present invention relates to a surface treatment method for improving the corrosion resistance of a product that is gold-plated on a silver processed product, and more specifically, after plating with Ni and Pd alloy plating on a silver processed product, gold plating and ultrasonic processing again. After washing the product using a composition composed of 30% by weight of thioacetal compound, 30% by weight of nonionic surfactant, 30% by weight of K 2 CO 3 , 10% by weight of alcoholic nonionic surfactant By surface treatment to improve the corrosion resistance.n n n The surface treatment method of the present invention,n n n A processing step of processing the shape with silver (Ag),n n n A nickel (Ni) plating step performed to form a prevention layer for preventing diffusion of silver (Ag) processed from silver (Ag) material to the outside;n n n Palladium (Pd) alloy plating step for corrosion protection on nickel (Ni) plated features,n n n A gold (Au) plating step of plating gold (Au) on a palladium (Pd) alloy plated shape,n n n Ultrasonic processing step of performing ultrasonic processing on gold (Au) plated shape,n n n A washing step of removing foreign matters from the ultrasonically processed shape,n n n 28 to 32% by weight of thioacetal compounds, 28 to 32% by weight of nonionic surfactants, 28 to 32% by weight of K 2 CO 3 , and 8 to 12% by weight of alcoholic nonionic surfactants A surface treatment step of mixing the composition with water (H 2 O) at 15 to 25 to 100 and immersing at 55 to 65 ° C. for 1 to 5 minutes,n n n It consists of a washing and drying step of washing and drying the surface-treated feature. |
