Abstract
In the present work, Al380 Al alloy and B4C metal matrix composite was fabricated with different weight fractions (1%,2% and 3%) using compo-casting method. The wear properties of fabricated composite is tested by pin on disc apparatus. On different loads of 30N,60N and 90N the wear tests are performed. The mechanical properties of hardness and tensile strength are performed on brinell’s hardness apparatus and Ultimate tensile machine. The study of homogeneous distribution of B4C particles were examined by scanning electron microscope (SEM) in the composites. The result shows that the Al380 Al alloy reinforced with B4C particles, that composite improves the mechanical properties and wear rate. Increasing of wear rate with the increase in B4C particles in composites. Using Opti- cal microscope, the study of worn surfaces of pins were analyzed.
Highlights
From the past decades in automobile industries, aerospace, defense academy is concentrated on lightweight materials like Al alloys
There is a dire need of novel material which possesses high hard- ness, tensile strength and wears resistance, properties that impro- vise the Al metal matrix composites
At 900oC the whole mixture is preheated before totaling into the molten metal. 250gms of matrix alloy is heated in a graphite crucible at 750oC temperature
Summary
From the past decades in automobile industries, aerospace, defense academy is concentrated on lightweight materials like Al alloys Because these Al Alloys having Excellent engineering properties like elevated tensile strength, high hardness, better wear resistance and outstanding thermodynamic strength properties. Vortex method is the best opted method for bonding of particle matrix where uniform distribution is at- tained in the reinforcement [23] This Al metal matrix product affects mechanical properties so it is fit for restricted conditions. There is a dire need of novel material which possesses high hard- ness, tensile strength and wears resistance, properties that impro- vise the Al metal matrix composites. This is attained by the in- crease of ceramic particles.
