说明

铝表面不能接受大多数电镀工艺,因为它们倾向于快速形成氧化物。氧化物的形成会抑制电镀的均匀性,导致沉积不均匀、附着力差或根本没有沉积。 通过首先将锌酸盐化学浸没镀锌溶液应用到适当准备的铝表面上,随后可以沉积高质量的化学镀镍膜。

一般描述

Aluminum surfaces are not receptive to most plating processes due to their tendency to form oxides rapidly.Oxide formation inhibits uniform plating, resulting in inhomogeneous deposits, poor adhesion, or no deposition at all. By first applying Zincate Electroless Immersion Zinc Plating Solution to a properly prepared aluminum surface, it is possible subsequently deposit high quality electroless nickel films.
 

应用

Plating onto aluminum involves a multiple step process.
1.Non-etch clean the aluminum surface for up to 5 minutes with a detergent-based cleaner. Rinse thoroughly with cascading water.
2. De-smut the surface for 10-30 seconds using an acid mixture. RTM A for plastics is a suitable agent for smut removal. Rinse again thoroughly.
3. Mild etch for 5-10 seconds in a 25% solution of Aluminum Etch Type A. Rinse again thoroughly.
4. De-smut a second time and rinse as in step 2.
5. Apply the first Zincate layer. Immerse the part in the Zincate solution for 1-2 minutes at room temperature until a gray color develops. Rinse.
6. Remove the first Zincate layer using 50% nitric acid for 30-60 seconds or until the deposit turns white. Rinse.
7. Apply a second Zincate layer for 30-60 seconds. Rinse thoroughly before applying electroless nickel to the surface.
