Shanmugasundaram A., Dr. Sanjivi Arul, and R. Sellamuthu, “Investigating the Effect of WC on the Hardness and Wear Behaviour of Surface Modified AA 6063”, Transactions of the Indian Institute of Metals, pp. 1-9, 2017.[Abstract]


The objective of this work is to reinforce Tungsten Carbide (WC) onto the surface of AA 6063 aluminium alloy using Gas Tungsten Arc (GTA) as heat source and investigate the hardness and wear properties. Based on number of trials, optimum GTA heat source parameters are finalized with reference to the proper fusion of base metal. It is found that the hardness is reduced after the application of heat. After the reinforcement of WC, the hardness returns back to the base metal value. In order to further to improve the properties, the reinforced alloy is heat Treated. The Microhardness of the reinforced and aged AA 6063 is increased by 50% with respect to base metal. The wear resistance of the reinforced surface is improved by 52% with respect to base metal. Characterization techniques like SEM, EDX and XRD are done and the presence of WC is confirmed. © 2017 The Indian Institute of Metals - IIM

Effect of reinforcing flyash to the surface of AA 6063 aluminium alloy using Gas Tungsten Arc (GTA) as a heat source and corresponding hardness variation have been studied. Heat source parameters such as current, electrode tip distance and tip angle are kept as constant and the work speed is varied. Reduction of microhardness is observed in the fusion zone after applying the heat on the specimens without flyash. Flyash of 38, 75 and 90 μm particle sizes were deposited onto the surface of AA 6063 alloy specimen using GTA as a heat source. The thickness of the modified layer is found to be 1.02 mm. The addition of flyash increased the hardness to that of the base metal. Further artificial aging increased the microhardness of the modified surface layer significantly compared to the base metal. The resulting modified layer was characterized by energy dispersive x-ray spectrometry (EDX) and X-ray diffraction (XRD) technique. © EDP Sciences, 2017.

S. R. Kasthuri Raj, Dr. Ilangovan S., Dr. Sanjivi Arul, and Shanmugasundaram A., “Effect of variation in Al/Si content on mechanical properties of Zn-Al-Si alloys”, International Journal of Applied Engineering Research, vol. 10, pp. 2723-2731, 2015.[Abstract]


An investigation was carried out to find the effect of Al/Si content on mechanical properties in Zn-Al alloys. Six different alloy compositions were cast with Zn at 60 wt. % and Si varying from 0 wt. % to 5 wt. %. The alloys were prepared using stir casting process and poured into permanent mould metallic die. Micro-hardness, ultimate tensile strength and percentage elongation of the alloy specimens were measured. The microstructure of the alloy without Si content showed the presence of Al rich α-dendrites and inter-dendritic Zn-rich η phases. The addition of Si content up to 2 wt. % to the alloy system showed uniformly distributed discrete particles of Si in addition to the features of the Si-free alloy. However, when the Si content of the alloys goes beyond 2 wt. %, the Si particles formed large clusters. It was found that the hardness and ultimate tensile strength of the alloy increased with increase of Si content up to 3 wt. % and then decreased when Si content increased further. The percentage elongation decreases up to 3 wt. % of Si and then increases. It shows that the Si content has significant effect on mechanical properties of Zn-Al alloy. © Research India Publications.

K. K. Suresh, Dr. Ilangovan S., Dr. Sanjivi Arul, and Shanmugasundaram A., “Effect of zn/cu content on microstructure and mechanical properties of al-zn-cu cast alloys”, International Journal of Applied Engineering Research, vol. 10, pp. 9325-9333, 2015.[Abstract]


A binary Al-Zn and five ternary Al-Zn-Cu alloys were produced using stir casting process by varying the Cu contents from 0-5 wt. % and keeping Al content as constant value of 60 wt. %. It was found that the micro-hardness and the ultimate tensile strength of the alloys increases significantly with increasing Cu content up to 2 wt. % which is due to solid solution hardening of Cu content in Al-Zn alloy. Further increase of Cu content results in the formation of hard and brittle θ phase which weakens the inter-dendrite region and marginally increases the hardness and ultimate tensile strength of the alloy. The percentage elongation of the alloy system decreases continuously with addition of Cu content. © Research India Publications.

High cutting temperatures affect the tool life, surface finish of the component and chip formation. In order to reduce the cutting temperature, suitable cutting fluids should be selected. In this work, water, coconut oil, compressed air, mixture of water and oil at room temperature and mixture of water and oil at 0 °C were used as cutting fluids during turning operation of AISI 1016 steel. In addition to this, dry turning was also performed. Turning operations were done using HSS cutting tool at different spindle speeds, while feed and depth of cut were kept constant. The influence of various cutting fluids on the cutting temperature, surface roughness and chip morphology were studied and compared. At minimum cutting temperature, reduced surface roughness and continuous chips were noticed when a mixture of water and oil were used as cutting fluid at 0 °C. © Research India Publications.

Al-6Zn-4Mg alloy blocks were prepared by stir casting process. The wear study was conducted by varying load, velocity and specimen temperature using pin-on-disc wear tester. It was observed that the wear rate (WR) increases with load at a constant velocity. The WR at constant load is less in the velocity range of 1.5 to 2 m/s. compared to the velocity range of 1 to 1.5 m/s. The specific wear rate (SWR) decreases rapidly between 10 to 20 N and marginally from 20 and 50 N. The SWR increases linearly with sliding velocity. The decrease in wear resistance is significant between 10 and 20 N and is marginal from 20 to 50 N. The wear resistance decreases linearly with increasing velocity. The WR decreases rapidly as the temperature of the specimen increases from 50 to 90ºC and further increase of specimen temperature from 90 to 125ºC, increases WR rapidly. The SWR also varied similar to WR versus temperature. The wear resistance of the specimen shows a reverse trend as compared with the WR and SWR. The variation of coefficient of friction (COF) with load, velocity and specimen temperature shows a marginal variation. © Research India Publications.

N. K. Robin, Dr. Ilangovan S., Dr. Sanjivi Arul, and Shanmugasundaram A., “Influence of nickel content on mechanical properties of aluminium-boron carbide hybrid composite”, International Journal of Applied Engineering Research, vol. 10, pp. 32311-32320, 2015.[Abstract]


In this work the influence of nickel (Ni) content on mechanical properties of aluminium matrix composite (AMC) was studied. Boron carbide was used as (B4C) reinforcement with aluminium (6061-T6) alloy. The nickel content was varied from 2 wt. % to 8 wt. % keeping boron carbide as constant value of 10 wt. %. The composite blocks were produced by stir casting method. The flux (K2TiF6) was added during melting process to improve the wettability of boron carbide content in the matrix. The dispersion of boron carbide and nickel particles were found to be homogeneous in the matrix by studying the microstructure using an optical microscope. It was observed that as the nickel content increases from 2 wt. % to 8 wt. %, the hardness value correspondingly increases from 121 VHN to 193 VHN. Similarly, the tensile strength also increases from 192 MPa to 305 MPa. The % elongation decreases from 16 to 9 with respect to increase in nickel content. The tensile strength increases and % elongation decreases with hardness of the alloy. © Research India Publications.
