Abstract

A method of producing composite oxide ceramic fluorine polymer layers on articles of aluminum, magnesium, titanium or their alloys, particularly of light metal components, includes introducing particles of fluorine polymers into the capillary system of an oxide ceramic layer. The particles have a particle size which at least in one dimension is smaller than the diameter of the capillaries. The article is then subjected to alternating pressure conditions.
