Abstract

Procedure for the protection of aluminum and aluminum alloy objects, by oxidation of the surface of these objects and formation of an oxide layer and then by two successive treatments of entanglement of this layer called respectively pre-entanglement and post-entanglement, characterized in that the pre-entanglement is carried out by immersion of said objects in a bath of alkaline pH at room temperature, containing in solution ammonia and at least one salt of a metal whose oxide is not precipitated in an ammoniacal medium.
