FIELD: metallurgy.
SUBSTANCE: invention relates to the field of application of coatings using electrophoresis and can be used in air industry and other engineering areas. The method includes application of coating on aluminium substrates by electrodepositing from water dispersion, containing lanthanide oxide, with a degree of oxidising +3 and/or +4, and non-geled phosphated epoxy resin, meanwhile before an electrodespositing of coating on the substrate the conversion coating containing the compound of metal IIIB or IVB group can be applied.
EFFECT: coating has high resistance to pore formation.
