Surface finishing for Al2O3 ceramics
A process for electroless copper plating on Al2O3 ceramic products was provided. The bath is composed of components A (containing potassium tartrate 35～45 g/L, sodium hydroxide 7～9 g/L and sodium carbonate 3～4 g/L) and B (containing copper sulfate 7～14 g/L, nickel chloride 1～2 g/L and formaldehyde 15～20 g/L) with a volume ratio of 3:1. The bath composition and technological conditions of surface pretreatment were given, including degreasing, roughening, sensitizing, activating, and reducing. The formulation and process parameters for electroplating copper followed by coloring in five different colors, which are widely demanded in the market, were introduced. The coatings obtained by the presented processes on Al2O3 ceramic products are smooth and bright, producing an elegant appearance and greatly extending their service lives. All these technologies have been successfully applied to practical electroplating production, showing a wide development future.
