Abstract : A method and apparatus for spraying a surface which comprises: introducing into a laser beam, a powder with the a vapor pressure from 10 to the minus 2 power to 10 to the minus 1 power atm. in excess of the ambient pressure at a temperature up to about 500 C. above the melting point thereof and with a heat-absorption coefficient from 0.2 to 1; and passing the laser beam over said surface. Since the method and apparatus can coat or alloy or dope a surface, a wide variety of protective coatings can be fabricated. (Author)
