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

Table 4

Variation of coefficient of friction with load for aluminum matrix alloy and silicon carbide based aluminum metal matrix composite at = 3.77 m/sec.

Sliding condition & load	COF for aluminum matrix alloy	COF for silicon carbide based aluminum metal matrix composite
Dry 10 N	0.72	0.56
Dry 20 N	0.63	0.43
Dry 30 N	0.50	0.35
Lubricated 10 N	0.58	0.44
Lubricated 20 N	0.47	0.32
Lubricated 30 N	0.37	0.25

Track diameter = 120 mm, = 600 rpm, sliding speeds = 3.77 m/sec, and = 600 sec.
