Study of Tribological Behavior of Silicon Carbide Based Aluminum Metal Matrix Composites under Dry and Lubricated Environment

Table 3

Variation of coefficient of friction with load for aluminum matrix alloy and silicon carbide based aluminum metal matrix composite at = 3.14 m/sec.

Sliding condition & load	COF for aluminum matrix alloy	COF for silicon carbide based aluminum metal matrix composite
Dry 10 N	0.65	0.42
Dry 20 N	0.57	0.37
Dry 30 N	0.47	0.30
Lubricated 10 N	0.46	0.32
Lubricated 20 N	0.43	0.25
Lubricated 30 N	0.36	0.19

Track diameter = 100 mm, = 600 rpm, sliding speeds = 3.14 m/sec, and = 600 sec.
