Piston with Graphite on the
Surface
The
quality of the graphite is lubricative, high
compressive strength ,heat-resistant,good heat
transmit ,stable temperature,corrosion resistant,low
friction(0.11 in ordinary)so when the piston is
sprayed with graphite in skirt,the position is
improved not only the initial work quality but also
dropped the friction between the position and
cylinder. |
