ANODIZING AND MICRO-ARC OXIDING OF DEFORMABLE ALUMINUM ALLOYS WITH COLORING

Description of the project: The proposed development involves the modification of electrolytes and modes of anodizing, microarc oxidation, to achieve the required functional and decorative properties of the surface of products. The process is carried out on standard galvanic equipment; when applying the coating, it is necessary to cool the electrolyte to 10-17 ^° C

Advantages: –
no need for special preliminary surface preparation (the electric discharge itself cleans the treated surface); – the possibility of simultaneous electro
chemical coloring of the resulting coatings; – environmental friendliness and non-
aggressiveness of electrolytes; – the possibilit
y of obtaining thick films – up to 400 microns; – hig
h microhardness (up to 2500 HV ) and wear resistance of coatings; –
increased adhesion;
– low porosity (up to 2-3%) of the obtained MAO coatings.
