一种不锈钢设备在高温非氧化性介质中的防腐处理工艺
摘要：
一种不锈钢设备在高温非氧化性介质中的防腐处理工艺属于特殊电镀技术领域，能够实施设备的现场镀覆及修复。本发明依次包括表面预处理和电刷镀步骤，其特征在于，电刷镀的镀液组成为：钯盐Pd(NH3)4Cl2：其计量以Pd质量计5～12g/L；NH4Cl：50～125g/L；(NH4)2HPO4：50～100g/L；浓度为28％的NH3·H2O：50ml～150ml；EDTA·Cu：1～5g/L；EDTA·2NH4：80～200g/L；其余为水；pH值为7～8；工艺参数为：电压：4V～10V，镀笔作阳极，工件作阴极，镀笔相对工件速度：8～12cm/s，温度为常温。该工艺操作简单，成本相对较低，效率高，环保性能较好。
摘要（英）：

The invention discloses an anti-corrosion treatment technique of stainless steel equipment in high-temperature non-oxidizing medium, which belongs to the field of a special electroplating technology field and can be used for carrying out on-spot plating and repair. The invention in turn includes the steps of surface pretreatment and electric brush plating and is characterized in that the plating solution for the electric brush plating comprises: palladium salt Pd (NH3) 4Cl2:5-12g/L (measured according to the quality of Pd); NH4Cl: 50-125g/L; (NH4) 2HPO4:50-100g/L; NH3.H2O (28% concentration):50ml-150ml; EDTA.Cu: 1-5g/L; EDTA.2NH4: 80-200g/L; water as the rest. The pH of the solution is from 7 to 8. Technological parameters: voltage: 4V to 10V; plating pen as anode; workpiece as cathode; plating pen velocity relative to workpiece: 8 - 12cm/s; temperature: normal temperature. The technique has the advantages of simple operation, low cost, high efficiency and good environmental protection.
