    Electrochemical doping of alkali metals into C60 thin film (1995)
    Springer
    Journal of superconductivity 8 (1995), S. 5-8 
    Details
    ISSN: 1572-9605
    Keywords: C60 film ; alkali metal ; voltammetry ; electrochemical doping

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract The electrochemical properties of an evaporated C60 film were studied by voltammetry in organic electrolyte solution. Four reversible reduction waves were observed, corresponding to the formation of alkali metal salts of fullerene, A x C60 (A∶ Li, K, Rb,x=1, 2, 3, 4). The voltammograms observed for each cation species were compared and discussed in relation to the cation radius. The change of optical density spectrum by the redox reactions was measured in the wavelength range of visible light. The resistivity of a C60 film protected by a polyimide film decreased rapidly by four orders of magnitude after the electrochemical doping of potassium ions.

    Wear test of cemented tungsten carbide at high atmospheric temperature (400°C) (2000)
    Springer
    Tribology letters 8 (2000), S. 130-145 
    Details
    ISSN: 1573-2711
    Keywords: cemented WC–Co alloy ; wear ; pin-on-disc wear testing machine ; fluorescent X-ray analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Cemented tungsten carbide–cobalt (WC–Co) alloy has good mechanical properties, so it is widely used for cutting tools, wear-resistant dies and rolls, and shock-resistant punching dies. In this study, a wear test between cemented WC–Co alloy and carbon steel is carried out using a pin-on-disc wear-testing machine. The characteristics as to wear rate, coefficient of friction and surface roughness are investigated. Pin specimen and disc specimen surfaces are analyzed by a fluorescent X-ray analyzer. In addition, the wear characteristics of WC–Co alloy are confirmed by SEM observation of the microstructure of the cemented WC–Co alloy specimen.
