摘要：
Intake of lead is harmful to the human body. Therefore, it is necessary to substitute other alloying elements for lead in Cu alloys. Using a Cu-9.5 mass%Sn alloy powder and CaF2, which has sliding properties equal to lead, a composite sprayed coating (by flame spraying) was developed. The results were as follows. A composite sprayed coating with the desired characteristics was successfully produced. The area fraction of the CaF2 layer in the composite coating increased with the increase in the blend ratio of CaF2 in the blended powder. The wear resistance of the composite coating containing CaF2 was excellent. As a result it was determined that CaF2 in the composite coating was effective as a sliding material substitute for lead.
