抄録

Double oxide, Sr_xCa_1-xCuO_y has a layered structure in which Ca (Sr) is sandwiched between CuO₂ layers. This crystal structure is expected to give low friction due to its low shear strength between laminas. In this work, various kind of Sr_xCa_1-xCuO_y with x=0.0 to 1.0 were prepared from SrCO₃, CaCO₃ and CuO by sintering method. The compositions of these products were examined by X-ray diffraction. The sample powders were blended in oil (squalane) and grease, and their load carrying capacities were evaluated by a cylinderon-plate type tribometer and a four-ball machine, respectively. As a result of the tests, Sr_xCa_1-xCuO_y with x=0.0, 0.14, 0.90 and 1.0 showed low friction (about 0.1) and high load carrying capacity (4900N). It was found from SEM and EPMA results that the worn surface was smooth, and that a thin solid lubricating film containing Ca, Sr and Cu was formed on the rubbing counterface. Also, the oxides with x=0.9 and 1.0 showed superior properties under extreme pressure in four-ball machine testing.
