Surface electroplating process for tungsten layer on aluminum oxide product
The invention discloses a surface electroplating process for a tungsten layer on an aluminum oxide product. Step 2, oil removal; primary washing; step 3; step 4, alkaline etching; step 5, activation; step 6, palladium activation; carrying out post-soaking; step 7; step 8, nickel plating; step 9, cleaning for the second time; step 10, dehydrating; step 11, water blowing; according to the method, the procedure steps are simple, the involved occupied area in the whole production process is saved, firstly, deoiling treatment is conducted, then the surface of the part is cleaned and aired for multiple times, the concentration and the micro-etching effect of a micro-etching solution in the next alkali etching procedure are guaranteed, then activation, palladium activation and post-immersion are conducted, so that combination of a plating layer is tighter, and the surface of the part is protected; the plating layer of the manufactured part is not prone to falling off and good in adhesiveness, solutions in all the process steps are convenient to adjust, continuous machining after shutdown and preparation of the needed solution is not needed, and the working efficiency and quality of the whole production process are improved.
本发明公开了一种用于氧化铝制品上钨层的表面电镀工艺，包括以下步骤，步骤一；除油：步骤二；初次水洗；步骤三；碱蚀：步骤四；活化：步骤五；钯活化：步骤六；后浸；步骤七；化镍：步骤八；二次清洗：步骤九；脱水：步骤十；吹水：步骤十一；烘烤：本发明中的工序步骤简单，节省了整个生产过程中的涉笔占地面积，首先进行去油处理，然后对零件表面进行多次清洁，并晾干，保证下一步碱蚀工序的微蚀溶液的浓度和微蚀效果，再进行活化、钯活化、后浸，使得镀层的结合更加紧密，制造后的零件镀层不易脱落，附着性好，所有工序步骤中的溶液调整方便，无需停工调制所需溶液后再进行继续加工，提高整个生产工序的工作效率和质量。
