  • Composite phosphate coatings
    Patent number: 11505868
    Abstract: A method for providing composite phosphate conversion crystal coating, including the steps of: mixing powdered materials with metal oxide particles, thereby providing a composite metal oxide powder including particles of at least one additional powdered material, the at least one additional powdered material providing additional functionality to the phosphate conversion crystal coating; pretreating a substrate by depositing particles of the composite metal oxide powder on the substrate; treating the substrate with a phosphate coating solution, resulting in the composite phosphate conversion crystal coating forming on the substrate which contains fixed particles of the at least one additional powdered material.
    Type: Grant
    Filed: November 7, 2016
    Date of Patent: November 22, 2022
    Assignee: PHOSFAN LTD.
    Inventors: Avraham Sheinkman, Itzhac Rozentul
  • Method for applying ultrafine phosphate conversion crystal coatings
    Patent number: 11142828
    Abstract: A method for providing phosphate conversion crystal coating, the method including the steps of: pre-treating a substrate by depositing metal oxide particles on the substrate; treating the substrate with a phosphate coating solution, resulting in the phosphate conversion crystal coating forming (crystallizing) on the substrate.
