Abstract:
A method of producing a half bearing comprising:preparing a backing member having a concave surface with an apex area;disposing the backing member in a coating chamber having a gas atmosphere;applying an overlay of a metallic alloy to the concave surface of the backing member by means of electron beam vapor deposition to develop a matrix of a first component of the metallic alloy and having a fine dispersion of at least a second component of the metal alloy dispersed in the matrix of the first component, and wherein the second component has an atomic weight greater than that of the first component; andcharacterized in that maintaining the gas atmosphere within the coating chamber at a pressure of 0.1 to 5 Pa in the apex area of the backing member during the application of the overlay to the backing member.
