At the Faculty of Mechanical Engineering of the Gdańsk University of Technology a research was undertaken on new metallic composites of potentially high wear resistance in reciprocating sliding. Composites were composed of ferrous powder or cutting carbon steel (N9) in cast aluminium alloy (AlSi11) matrix. A reaction between aluminium and iron was anticipated to result in the strengthening phases forming in the material. The composite materials and a reference non - composite were tested on the TPZ-1 tribometer in reciprocating unlubricated sliding against cast - iron. Tests were carried out at 5 MPa surface pressure and speed of O.1 m/s. Wear resistance was different for each material tested. The highest wear rate was exhibited by reference aluminium-silicon alloy. In composite materials the wear was slower. The exact influence of factors such as the time of mixing of the iron powder with the aluminium base material on the wear ratę remains still to be established. The friction coefficient characteristics vary with the material tested. The most stable friction coefficient was observed on unmodified aluminium - silicon alloy. A simple relation between the value of the friction coefficient and the wear rate among the tested materials was not observed yet.
