  • Adherent apatite coating on titanium substrate using chemical deposition
    Patent number: 7785648
    Abstract: An adherent bioactive calcium phosphate coating is formed on a titanium or titanium alloy substrate by immersing the substrate in an acidic calcium phosphate solution to form a non-apatitic calcium phosphate coating on the substrate. In a second step the coated substrate can be converted to a less reactive coating by being immersed into a basic or neutral solution to convert the coating into an apatite. However if a relatively reactive coating is desired, the second step can be dispensed with.
    Type: Grant
    Filed: September 21, 2005
    Date of Patent: August 31, 2010
    Assignee: New York University
