Abstract

This study presents an experimental investigation on the wear resistance properties of Al6061cor and mixed (Al 6061+1%CNT)cor. CNT is important in improving the quality of the coating due to the extraordinary mechanical and physical properties of the CNT, namely exceptional high strength to weight ratio, high aspect ratio, and high fracture strain and high flexibility. The layer is obtained from the friction surfacing process , utilizing the friction that occurs between the surface / substrate with the consumable rod. Consumable rods are Al6061cor and mixture ( Al6061 + 1% CNT) in the casting process with a diameter of 16 mm length 125 mm. Consumable Rods with constant pressure and constant rotation with speeds up to 3000 rpm move around the substrate with a table speed that varies 3.5, 4.2, and 5 cm / minute. The coating results are then analyzed to determine wear resistance according to ASTM G99-04 abrasive methods with variations in wear time for each specimen. Wear resistance of Al6061cor and (Al6061 + 1% CNT) cast layers with varying table speeds obtained the best results at speeds of 3.5 cm / min with thickness of 0.23 mm, width of 1.6 mm for Al6061cor layers and thickness of 0.25 mm, width of 1.8 mm for layers (Al6061 + 1% CNT) cast. Pengujian wear show that the wear rate increases with the length of time used in the process of wear. The highest wear rate value contained in the Al layer type 6061 cast in each variation of the time used . The wear rate ( Al 6061 + 1% CNT ) cast   is lower than the wear rate in the Al 6061 cast.
