An electron microscopy study of the effect of Ce on plasma sprayed bronze coatings

Abstract

The Cu-Al eutectoid alloy is an excellent material for mould due to its superior low friction. The conventional sand casting technique, however, is not feasible to fabricate high Al bronze because of high hardness and brittleness. Plasma arc spray has been used to produce high Al/Fe bronze coatings for mould. The inherent impurities such as H, O, N, S during the spray, however, may affect the coating's mechanical strength. One approach is to utilise the active rare earth Ce to clean up these impurities. The study is to investigate the effect of Ce on the microstructure, which has few reported in the literature.

Study on Friction and Wear Properties of Plasma and Laser Coatings of Aluminium Bronze Powder

“…A new type of aluminum bronze alloys Cu-14Al-X(chemical composition is listed in Table 1)was adopted to the experiment [4]. The substrate is AISI 1045steel.…”
