Non-Chromate Aluminum Pretreatments

William Nickerson, Craig Matzdorf

Open publisher page 10 citations

Abstract

Abstract : Aluminum finishing in Department of Defense applications utilizes chromate chemistries for anodizing, anodic sealing, and pretreatment (both for conversion coating aluminum substrates and for treating aluminum-based coatings deposited on steel). The most ubiquitous use of chromate coatings is in the conversion coating of aluminum alloys for use as-deposited or prior to organic coating application. These coatings are very thin, inexpensive to produced, and can be applied by immersion, spray and wipe techniques. However, chromate conversion coatings contain hexavalent chromium, a known carcinogen. National and international regulations are restricting the use of this material. This report presents the results of laboratory and field tests to demonstrate and validate several non-chromate aluminum pretreatments.
