Summary:This review covers main approaches to development of inhibited conversion formulations for chemical oxidation of aluminum alloys. A mechanism explaining the formation of conversion coatings on aluminum alloys from chromate conversion baths is proposed; the protective properties of the resulting coatings are characterized. It is demonstrated that various modified methods for the preparation of chromate conversion coatings on aluminum enhance their protective properties, however, without solving ecological problems. Among alternative corrosion inhibitors used in chemical oxidation of aluminum alloys, molybdate-containing formulations are worth noting and have been much investigated. The most promising approach is to develop corrosion inhibitors for use during both the formation of a conversion coating and its subsequent filling with compounds chemisorbable at the modified oxide.[PUBLICATION ABSTRACT]
