The disadvantage is the low mechanical strength and corrosion resistance of the coating. It is destroyed when in contact with sea water and active metals. This method can be done at home.
The process takes place at room temperature or higher (no more than 50°C). After degreasing, the workpieces are mounted on a hanger that holds them in an electrolyte solution.
Anodizing continues until a milky coating appears chinese overseas australia data the surface. After stress is removed, the workpieces are washed in cold water. Then the parts are subject to painting. They are painted by placing them in a container with hot dye. After which the result is fixed for 1 hour.
Methods of color anodizing of aluminum
Cold technology
To carry out anodizing of aluminum you need:
12 V power supply (battery, stabilizer);
aluminum wires;
rheostat;
ammeter;
containers for solutions.
The cold technology is distinguished by the fact that the growth of the anodized coating on the metal side occurs at a faster rate than its dissolution on the outside.
