| Abstract: | In the paper,pretreatment process for Electroless Plating Copper on Q235 steel workpiece were investigated.A proper formula and processing condition of degreasing and derusting for the workpiece were obtained.The experiments results show:(1)In alkaline conditions the optimal degreasing were:NaOH:40~50 g/L,anhydrous Na2CO3: 40~50 g/L,Na3PO4: 40~50 g/L,temperature: 80~100 ℃,time: 3~5 min;(2)The derusting effect was good at the condition of H2SO4(10 %)and right amount Corrosion inhibitors rodinem;(3)Adding surfactants OP-10 and betaine in the mixed acid of hydrochloric acid and sulfuric acid,one-time degreasing and derusting solution can been made up.The optimal derusting were: HCl: 180 mL/L,H2SO4: 100 mL/L,OP-10 10 mL/L,betaine: 5 %,time: 5~8 min. |
