Versatility of Nickel-Aluminium Bronzes as Wear Resisting Materials

Résumé

The paper presents the results of experimental research regarding the establishing of some chemical positions of the nickel-aluminium bronzes used as monoblock and bimetallic bearings. The areas of the applications are discussed with reference to the working property required of these alloys. Normally a combination of several properties finally governs the selection of a particular material. The correlations between chemical compositions, structures and properties are analysed with a view to selecting the material for certain application. The wear resistance and the corrosion behavior into seawater of the nickel-aluminium bronzes with variable content of iron and manganese are studied.
