FIELD: engines.
SUBSTANCE: invention relates to a wear-resistant catalytically active thermal barrier ceramic coating of parts of internal combustion engine chambers, deposited by micro-arc oxidation. Said coating is double-layer with thickness of 15-150 mcm. First coating layer has thickness 5-100 mcm with aluminium content of not less than 90 mol%. Second porous layer with thickness of 10-100 mcm consists of aluminium oxide and cerium oxide with content of 1 to 50 mol%.
EFFECT: higher reliability and efficiency of chamber of internal combustion engine, higher efficiency of internal combustion engine, reduced emissions of carbon monoxide, carbon dioxide and hydrocarbons into environment.
