Effect of titanium addition on the dry sliding wear behaviour of hypereutectic Al-Si alloys are investigated at elevated temperatures. Wear tests are conducted for varying normal pressure from 0.20 N/mm 2 to 0.98 N/mm 2 , for varying sliding velocity from 0.94m/s to 3.77 m/s and varying sliding distance from 282.74 m to 1696.46 m. In this present investigation, hyper eutectic aluminium based alloys containing 13% and 20% weight of silicon; with addition of titanium is synthesized using casting method. Wear behaviour is studied by using computerized pin on disc wear testing machine. Worn surfaces were examined and analysed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The wear results show that the wear rate increases with increase in normal pressure (0.20 N/mm 2 to 0.98 N/mm 2) and sliding distance (282.74 m to 1696.46 m), but wear rate decreases with increase in sliding velocity from (0.94 m/s to 3.77 m/s).

The gear is one of the important elements of the machine in the mechanical power transmission system. Straight gear is the most basic gear used to transmit power between parallel axes. The spur gear generally fails to bend the fault or contact failure. The contact tension in the coupling gears is the key parameter in the design of gears. This article presents the stress analysis of the coupling teeth of the straight gear to find the maximum contact stress on the gear teeth. The tooth profile is generated using the CATIA software and the analysis is done using the finite element method using the ANSYS software.
