Aluminum alloy electroplating pretreatment

Composite plating in electrolyte solution is to add one or several kinds of insoluble solid particles, the reduction of metal ions, formation of coating at the same time, the insoluble solid particles distribution of uniform dispersion in metal coating, form a composite coating. The electroplating method can be used to prepare multiple composite coatings, which are composed of wear-resisting, self-lubricating, dispersion strengthening, corrosion resistance and other composite coatings, as well as an intermediate composite coating that enhances the bonding strength of organic coatings. Composite electroplating has the following characteristics: the process is simple, the coating is diversified and dispersed phase particle variety.

Hanging fixture

For aluminum alloy plating, the fixture is a prerequisite, especially for large parts, which must be sufficiently large

The area is used to ensure that the electric conduction is good, and do not use the copper plated fixture, because the copper contact and the aluminum are replaced by copper and the contact is bubbling.

Alkali corrosion

In the protection of oil and wax clean under the premise of the concentration of alkali corrosion, temperature, time control is crucial, because of dissolved aluminum in the sodium hydroxide is preferred, prone to excessive corrosion and alkali corrosion uneven phenomenon.

Acid etching (descaling)

Because of the aluminum alloy is made up of copper, iron, magnesium, silicon and other ingredients, usually do not react with lye, so must pass the acid corrosion (cleaning) process to remove the oxide, make surface exposed clean metal substrate. Acid corrosion (descaling) fluid must control the temperature, concentration and time of the three elements, especially temperature, this is the culprit, summer aluminum easy foaming must have frozen cooling equipment in the summer. For aluminum alloy with high magnesium, it is necessary to use the following process to obtain a good coating. The etching process for: sulphuric acid 15% (volume percentage concentration), 2 ~ 5 m I n time, temperature of 80 ℃. Descaling process for the following: nitric acid 50%, temperature of 15 ~ 25 ℃, 1 ~ 2 m I n time, again heavy zinc.
