    Abstract

    Electron spectroscopy for chemical analysis (ESCA) has been used to study the surface chemistry of electroless nickel-boron coatings. Changes in relative surface composition and element oxidation state were observed for boron, nickel, thallium, and sulfur as the coating was heated at 10-5 torr and heated in air. Under these conditions, boron was more easily oxidized than nickel, accounting for the oxidation resistance of the coating as compared to nickel metal. A small portion of sulfate stabilizer in the coating bath was reduced to sulfide and codeposited during the electroless plating process.
