Manufacturing process of a sliding bearing having a sliding surface of copper/multiple alloy

摘要

The method involves dissolving a hard phase constituent (2) of a copper multi-component alloy at a sliding surface by using an acid e.g. mineral acid, hydrochloric acid, sulfuric acid and nitric acid. A soft phase constituent (3) of the material alloy remains on the sliding surface. Cavities are formed in an area of the dissolved hard phase component and are designed as lubricant deposits. An independent claim is also included for a sleeve bearing comprising a copper-aluminum multi-component bronze.
