Corrosion Protection Without Anodization: Sol-gel Coatings for Aluminum Alloys
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.
