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.
