INSTALLATION FOR FORMING PROTECTIVE DECORATIVE COATINGS ON TITANIUM Russian patent published in 2023 - IPC C25D11/26 

FIELD: medicine.

SUBSTANCE: invention can be used in various industries, including in medicine in the manufacture of biocompatible metal products that require surface treatment in order to obtain coatings with increased anti-corrosion properties and heat and wear resistance. The micro-arc oxidation installation for the formation of protective decorative coatings on titanium contains a power source to which a power transformer is connected, which is then connected through a control unit to a bath, which is the cathode. The bath contains an electrolyte and is configured to immerse the part being oxidized into it, which is the anode, which is connected to the output of the power transformer. The bath is placed in a housing with water with the possibility of cooling the electrolyte. The tank containing the electrolyte is connected to the bath through a pump with the ability to supply electrolyte to the bath. An incoming pipe with the ability to supply cold water to the bathtub body and an outgoing pipe with the ability to remove heated water from the bathtub body are connected to the bathtub. The control unit is connected to a power transformer, a bath, a part to be oxidized, a pump, and contains devices for adjusting the parameters of the microarc oxidation process. This ensures minimal roughness of the resulting coatings, high adhesion of coatings with a thickness of 10–200 microns to 400–800 microns to the metal base, wide possibilities for regulating the process speed, optimal process conditions, allowing to achieve high operational parameters while simplifying and reducing the composition of the equipment.

EFFECT: obtaining installation for forming protective decorative coatings on titanium.
