Iridium oxide coating   Our plants  Chief Chemist’s Division has developed and implemented the procedure of current-conducting iridium oxide coating deposition on the electrode details made of titanium applied for pacemakers production.   The process of IrO2 coating deposition consists of the following sequential operations:   chemical etching of the electrodes surface; surface coating of electrodes with iridium salt; thermal decomposition of the iridium salt with formation of a corrosion-resistant current-conducting layer of iridium oxide and titanium oxide mixture on the product surface.  The new technology enables to coat iridium oxide on a wide range of titanium electrodes. Preliminary chemical etching of electrode surface improves the adhesion of the film that consists of a mixture of iridium oxide and titanium oxide to a titanium substrate. The thickness of iridium oxide and titanium oxide mix layer ranges from 2 to 5 micrometers.   The developed technology enables to coat the corrosion-resistant current-conducting layer of iridium oxide and titanium oxide mix on other titanium products, such as plates, bars and tubes.

Our Central Analytical Laboratory  provides analytical services to outside organizations in performing chemical tests of precious metals and items containing them on contractual basis.
