out.
4 Conclusions
The following facts can be found on the basis of this study:
• Sample-I show less than 50% of the composition’s average porosity and 98.5%
of its theoretical density.
• Sample-II indicates a lower friction coefficient and higher wear resistance that
will be ideal for the manufacture of automotive components such as automobile
components and cylinder pistons.
• As the friction coefficient decreases, it reduces the friction force (caused by wear
and tear of moving parts), thus increasing the engine’s mechanical efficiency,
decreasing fuel consumption and lubricating costs.
