In special machine elements, architectural
sections, automobiles and frame systems, aluminium alloy 6063 has a wide
application. AA6063 has a high strength to weight ratio, but poor wear
resistance and hardness characteristics. Friction Stir Processing (FSP) is a
method of surface modification in which the surface's mechanical properties can
be enhanced by strengthening ceramic particles. The surface property of
Aluminium Alloy 6063 is modified in this present investigation by strengthening
the powder particles of Boron Carbide (B4C) through FSP. The distribution of
B4C particles was investigated by keeping the volume fraction (22.38 percent)
constant for various reinforcement techniques, based on hardness and impact
power. The tool pin profiles such as the threaded cylindrical and square pin
were also compared via various reinforcement techniques for the best
distribution of B4C in the base metal surface. The instrument
1200 rpm of rotational speed, 40 mm / min of travel speed and 10 kN of axial
force are kept constant. By reinforcing Boron carbide particles into the base
metal surface, friction stir processing is an efficient way to increase
hardness. When the B4C particles are packed into the serial holes and friction
stir is processed with the square pin profile tool, the optimum hardness and
impact strength is achieved. The uniform distribution of B4C particles is
demonstrated by increased hardness in the Stir field. For surface modification
via FSP, the serial holes reinforcement method with a square pin instrument may
therefore be used.
