Introduction In recent years, the use of titanium (Ti) and Ti alloys as implant materials has been increased in comparison with many other metals.
To improve the healing properties, coating cp-Ti materials with HA is a common technique.
Moreover, it has been reported that the materials prepared by sol-gel deposition are more bioactive than those prepared by other methods [14].

Introduction Particulate reinforced metal matrix composites are considered to be important materials due to their high strength, high stiffness and low density [1].
These include test geometry, load, test duration, materials properties and environmental factors such as temperature, humidity etc.
Frictional materials used nowadays containing conventional organic binding agent exhibit poor frictional stability.
