## Title

- title: Improved wear and friction properties by self-formed SiC layers in Mg/SiC
    composites
  title_type: original
  lang: en

## Description

- description: The tribological properties are evaluated using several types of Mg/SiC
    composites, which SiC powders with particle sizes of 20~30 nm, 130 nm and 2~3
    μm are dispersed in up to 25 % by volume fraction.  Sound and bulky Mg/SiC composites
    are successfully fabricated by powder-metallurgy combining extrusion process.  The
    initial SiC particle size and volume fraction affect the wear and friction properties.  The
    specific wear rate increases with increasing contents of SiC particles, regardless
    of the initial SiC particle size.  However, when the SiC particle size is larger
    than a certain size and its content is greater than 10 %, the friction coefficient
    decreases rapidly.  In the surface observations after friction tested specimens,
    the element map shows the Mg ratio relative to Si ratio (= SiC) increases with
    reducing friction coefficient.  This indicates that good wear resistance is due
    to the formation of self-formed SiC layers during the friction process.
