An engineering methodology for calculating both the stress state and the strength of the double-layer ceramic–aluminium coatings loaded with a hard indenter is developed. Influence of the oxide-layer thickness on the permissible arbitrarily oriented loading value is studied. An optimal thickness of the oxide layer, which provides the maximum resistance of coating to indentation, is calculated.

Key words: plasma–electrolytic oxidation, double-layer coating, indentation, strength, ceramics, aluminium.
