TLDR
In this paper, a review of the most recent developments in the application of common inorganic protection layers based on conversion coatings for Al alloys is presented, including those formed through anodisation, as potential replacements to the most widely used treatments based on chromate chemistry.Abstract:
Anticorrosive protection of Al alloys still depends heavily on the use of chromates, which are widely and universally employed as chromate conversion coating and chromic acid anodising pretreatments. The replacement of chromate based treatments with more environmentally compliant processes and materials has been identified as a high priority. The aim of this paper is to review the most recent developments in the application of common inorganic protection layers based on conversion coatings for Al alloys. The review lists and discusses the majority of conversion coatings, including those formed through anodisation, on Al alloys as potential replacements to the most widely used treatments based on chromate chemistry.read more

The icephobic performance of alkyl-grafted aluminum surfaces.
TL;DR: This work analyzes the anti-icing performance of flat aluminum surfaces coated with widely used alkyl-group based layers of octadecyltrimethoxysilane, fluorinated alkylsilane and stearic acid as they are subjected to repeated icing/deicing cycles to demonstrate the vulnerability of smooth aluminum surfaces to gradual degradation of their hydrophobic and icephobic properties.
