The coating of the alumina platelets with high-refractive metal oxides, such as with titanium dioxide and iron(III) oxide leads to strongly reflecting effect pigments. These pigments possess a strong glitter effect. The coating process is analogous to that used for metal oxide mica pigments except it starts from an aqueous suspension of Al 2 O ...
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion , to improve the adherence of other coatings, for lubrication , or for aesthetic ...
Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys. [ 1 ] : p.1265 [ 2 ] The coating serves as a corrosion inhibitor , as a primer to improve the adherence of paints and adhesives , [ 2 ] as a decorative finish, or ...
A white surface treated with an optical brightener can emit more visible light than that which shines on it, making it appear brighter. The blue light emitted by the brightener compensates for the diminishing blue of the treated material and changes the hue away from yellow or brown and toward white. [2]
Black for aluminum. Boil a solution of 20 g ammonium molybdate and 5 g of sodium thiosulfate in a liter of water, immerse the objects, rinse, dry, wax or lacquer after the development of color. [31] Lustre colours. Use a solution of 280 g of sodium thiosulphate, 25 g of cupric acetate and 30 g of citric acid. It can be used on copper and its ...
The coating types mentioned above are applied to protect tools including special tools for medical applications. They are also used as decorative finishes. One derivative of TiAlN coating technology is the nanocomposite TiAlSiN (titanium aluminium silicon nitride) which was developed by SHM in the Czech Republic and now marketed by Platit of ...
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
