【摘要】 提供了一种Al2O3陶瓷制品化学镀铜的工艺,其溶液由组分A(含酒石酸钾35～45g/L、氢氧化钠7～9g/L和碳酸钠3～4g/L)和组分B(含硫酸铜7～14g/L、氯化镍1～2g/L和甲醛15～20g/L)按体积比3:1混合而成。给出了表面预处理(包括除油、粗化、敏化、活化、还原等工序)的配方及工艺条件。介绍了市场需求量较大的镀铜后五色系实用着色工艺配方及参数。Al2O3陶瓷制品应用该工艺配方处理后,所得镀层外观平整、光亮,在获得优雅外观的同时,大大延长了使用寿命。这些技术均已在生产实践中获得成功应用,具有广阔的发展前景。更多还原

【Abstract】 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 coloring in five different colors were introduced,which is carried out after copper electroplating and widely demanded in large quantities in the market.The coatings 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.更多还原
