Corrosion Protection Without Anodization: Sol-gel Coatings for Aluminum Alloys
SPONSORED BY: Momentive Performance Materials
Aluminum and its alloys are widely chosen materials for several industrial sectors including automotive, aerospace, household appliances, marine, architecture, etc. This paper presents the development of sol-gel based protective coatings that adhere directly onto untreated aluminum alloys and offer abrasion, corrosion and chemical resistance with a thickness of less than ten microns. The technology proposed here is an alternative to the chemically intensive and time-consuming anodization process.
