Investigation On Specific Wear Behaviour Of Al7075 Metal Matrix Composite Material With Nano Tio2 Particles

[Full Text]



G T Danappa, R P Swamy, Raghavendra C R



nano composite material, specific wear rate, microhardness.



The hybrid metal matrix composite coating has found wide spread applications in the field of aerospace and automobile industries. In the present work the Al7075 is used as the major material and Gr micro particles along with nano TiO2 particles are reinforced in the composite material. The influence of nano TiO2 particles and Graphite particles in the composite material on specific wear rate is carried out. Normal load, sliding speed and sliding distance are kept constant for all the samples. Further work is concentrated on the influence of percentage of nano particles on the microhardness are evaluated. The results reveal that decrease in the specific wear rate by the presence of hard TiO2 and Graphite particles.
