Received: 16 December 2019 Accepted: 23 February 2020 The present experimental work focused for evaluating the bond strength and flash mass on deposition of Aluminum 6063 over IS 2062 low carbon steel by friction surfacing using different design of mechtrode face. Five design of mechtrode were chosen, named as MF1, MF2, MF3, MF4 and MF5 for carrying out the friction surfacing with different parametric combinations. Study had shown that the amount of flash mass produced by mechtrode was increased by increasing the mechtrode face contact area. Low flash mass (about 28% of the deposited mass) and high push off strength (79.4 MPa) were noticed in MF5 mechtrode samples. The micro hardness profile at the coating interface highlighted a highest increase of 18.6% hardness at specimen obtained from MF5 mechtrode in comparison with received mechtrode material. The bending test revealed that at high rotational speed (3000 rpm) and high axial force (6 kN) could increase the adhesive bonding at the interface zone. Cross section of coatings obtained from various mechtrode face had shown good bonding adherence quality and high mechanical interlocking which were confirmed by using high amplification FESEM images and the absence of aluminium ferrite (AlFe2O4) at deposition interface were authenticated by XRD analysis.
