Investigation of wear behaviors of C95200‐C95300 Cu‐Al‐Fe alloys

The paper's aim is to examine dry friction properties of the wear behaviors of the manufactured aluminum bronzes (C9500 and C95300) by using pin‐on‐disk type wear test device.

In this study, alloys were produced by casting C95200 and C95300 aluminum bronzes norms. Produced aluminum bronzes ingot after homogeneous were formed for wearing specimen. These test were conducted on two different alloys, in the sliding velocities 1, 1.5 and 2 m/s, with four different load (25, 37.5, 50 and 62.5 N) and for four different space (500, 1,000, 2,000 and 4,000 m). Wearing specimens tested for hardness and investigated in order to spectral electron microscope photographs.

After investigation, C95200 grain size was bigger than C95300. Furthermore, C95300 alloys were harder than C95200 because of more aluminum. Increasing load, sliding velocity and distance causes increasing wear. Coefficient of C95200 alloys was higher than C95300.

Aluminum bronzes show different properties according to the additional elements in them. Reliability of aluminum bronzes can be achieved by the control of chemical composition and the manufacturing method.

Very useful information for industries using or planning to produce C95200 and C5300 alloys is provided.

This paper identifies a resource need and offers practical help for a manufacturing operation.
