Composite anticorrosion coatings for AZ91D magnesium alloy with molybdate conversion coating
and silicon sol-gel coatings.
The conversion coating
cleaned and covered the outer layer of aluminum surface.
These processes include cleaning of metallic parts, non-destructive testing (inspection by penetrant liquid) as well as surface treatment including anodizing (protection of aluminum against corrosion), chromate conversion coating
, steel passivation, priming, painting and coating.
Chemical treatment by conversion coating
is an effective way of improving adhesion and corrosion protection properties of the organic coatings on the aluminum alloy.
This vehicle uses unique high-strength aluminum alloys with a special conversion coating
for adhesive bonding, Alcoa 951, and forming lubes (Quaker Chemical's DC2-90).
It is built with a die-cast aluminium housing and hinged full cut-off front frame with a textured, architectural bronze powdercoat finish over a chromate conversion coating
The allowed claims describe an environmentally benign, conversion coating
formulation, specifically applicable to copper and copper alloys.
They are available in all standard MIL-DTL pin counts and configurations and shell finish options include passivated nickel/gold plate or chromite conversion coating
NEI Corporation announced recently it has introduced a chromate-free, electrically conducting conversion coating
that significantly improves the corrosion resistance of lightweight metal alloy components.
The process is a non-toxic aluminium oxide conversion coating
that is 0.
This includes 3M's Liquid UV-Curable Adhesive and Light-To-Heat Conversion coating
Based on statistically designed experiments, a new process has been developed that delivers a more resilient copper conversion coating
