Abstract (en)
Aluminium and aluminium alloy articles, and method for making same, in which a thin, adherent, chemically formed coating is provided on the article surface to preserve the uncoated article appearance and provide a combination of functional properties including resistance to chipping and flaking during elevated temperature use, resistance to corrosion from chemicals in the form of gases or aqueous acidic or alkaline solutions including salt spray, organic solvents, oils and vehicle fuels and suitability as a base for paint for parts within the engine compartment of vehicles. The coating has a chemical complex of alkali metal-chromium-silicates.
