Beschreibung
Zusammenfassung:	The invention relates to a heat exchanger, in particular an evaporator for an air-conditioning circuit of a vehicle, said exchanger enabling a heat exchange between a first fluid and a second fluid and having surfaces intended to come into contact with one of said fluids, said surfaces being formed from aluminum and/or from aluminum alloy and coated with an alumina layer and with a layer referred to as a reinforcing layer that reinforces the natural protection of the aluminum, said reinforcing layer comprising a portion of organic substances and a portion of mineral substances, said portion of organic substances comprising at least one polymer and said portion of mineral substances comprising at least one substance capable of reacting with the aluminum in order to form an anticorrosion material.
