Abstract
Sr-Ca-Cu-O complex oxide thin films were prepared at different firing temperatures using a spin coating method. Sr0.14Ca0.86CuO2 having layer structure could be prepared at lower temperatures and the method was compared with ordinary firing methods. However, the single phase of Sr0.14Ca0.86CuO2 was not obtained under such spin coating conditions as in this study. The friction properties of four spin coating films sliding against a cemented carbide ball were investigated using a Bowden-Leben type friction tester. Comparatively low friction coefficient and high wear resistance under non-lubrication conditions were obtained with these complex oxide films.
