METHOD OF CREATION OF A PROTECTIVE DECORATIVE COATING Russian patent published in 2004 - IPC

FIELD: galvanotechnics.

SUBSTANCE: the invention presents a method of creation of a protective decorative coating and is dealt with the area of galvanotechnics and may be used for deposition of corrosion-resistant wear-proof coatings with the decorative appearance. The method of creation of a protective decorative coating includes a sequential deposition on a surface of an item by the galvanic method of an inner layer and an outer chromium layer. The inner layer is deposited as a zinc layer of 1-5 microns thick and outer chromium layer of 0.1-1 micron thick. At that deposition of the both layers is exercised in electrolytes with addition of brighteners. Technical result: the invention allows to decrease consumption of materials and the cost price of items; at that the coating provides reliable protection of items against corrosion, against mechanical damages and has the decorative properties kept at a continuous exploitation.

EFFECT: the invention allows to decrease consumption of materials and the cost price of items, ensures reliable protection against corrosion and mechanical damages.
