Abstract
Abstract In a method of producing a composite material for a sliding member having a sliding portion and a backing material which supports the sliding portion, the method comprises the steps of: disposing a powder or a sheet material for the sliding portion on the backing material; irradiating the powder or sheet material with laser beam or electron beam; melting or partially melting the beam-irradiated powder or sheet material; and quenching and solidifying the melted or partially melted portion, whereby the particles of the powder are integrated with one another and the powder in contact with the backing material are bonded thereto, or whereby the sheet material in contact wiht the backing material are bonded thereto.
