“…This resulted in the reduction in mechanical and tribological properties. Stir casting process variable such as stirring time, speed, size and position of the impeller and holding time are also plays an important role in determining the mechanical and tribological properties of AMMC [22]. So, it can be concluded that optimization of stir casting process parameters will help in solving these kind of issues in the hybrid AMMC.In overall the S1 sample results in very less wear rate.…”

The main objective of this research work is to study the effect of tribological behaviors and mechanical properties of Aluminium alloy 2014 (AA2014) hybrid composite reinforced with Boron Nitride (BN), Molybdenum disulfide (MoS2) and graphite (Gr). Stir casting technique is used for the fabrication of this composite material. The composite is subjected to three step ageing process which consists of solution heat treatment, quenching and aging. The base alloy was reinforced with 4 wt.% of BN, 4wt.% MoS2 and 4, 6, 8 wt.% of Gr. The hardness of the composite steadily increased up to 6 wt. % of graphite and further increase in graphite decreases the hardness. The sample with Graphite of 4 wt. % resulted in maximum hardness of 192 HV with respect to AA2014 base hardness. Addition of graphite up to 6% resulted in lower wear rate when compared to the base metal. The wear rate of sample with Graphite of 4 wt. % is reduced by 49 % from that of the base metal at maximum wear condition. Scanning Electron Microscope (SEM), Energy-dispersive X-ray Spectroscopy (EDX) and X-Ray Diffraction (XRD) were used for the characterization of composite.

“…At a high temperature of about 1500 °C, titanium dioxide and carbon undergo a chemical reaction to produce titanium carbide, a powder with a dark black appearance. When combined with Al alloy, TiC has been shown to acquire elastic and abrasion properties [4,5]. For applications requiring resistance to corrosion by alkali materials, zirconium silicate is used as a refractory material.…”

In the present work, the preparation of AA-6082/ZrSiO4/TiC hybrid composite is studied along with an analysis of the effects of electrochemical machining parameters such as feed rate of electrode (FE), voltage (VO), electrolyte concentration (EL), and electrolyte discharge (ED) rate on the output responses of the material removal rate (MRR) and surface roughness (SR) for Al hybrid composites. The experiments are carried out based on the Taguchi L16 orthogonal array and the important process parameters are found for MRR and SR. Each parameter contains four different levels that are FE (0.10, 0.15, 0.20, and 0.25 mm/min), VO (10, 15, 20, and 25 V), EL (15, 20, 25, and 30 g/lit), and ED (1.5, 2, 2.5, and 3 lit/min).The optimization software, namely, Minitab-17 version helps to find the contribution of each parameter on MRR and SR. The ANOVA result reveals that the feed rate of electrode is the highest contributing parameter, trailed by the electrolyte discharge rate and other process parameters for MRR and SR. A linear model of regression and interaction plots is also included to show the relationship between the parameters. From the observational results, the highest MRR (0.00953 mg/min) is attained by the parameter combination level of the feed rate of electrode of 0.20 mm/min, voltage of 25 V, electrolyte concentration of 20 g/lit, and electrolyte discharge rate of 1.5 g/, whereas the lowest MRR is found at FE of 0.10 mm/min, VO of 10 V EL-15 g/lit and ED of 2.5 g/litre. For SR, the maximum and minimum are recognized at FE2-VO4-EL3-ED2 (0.15 mm/min, 25 V, 25 g/lit, and 2 lit/min) and FE1-VO1-EL1-ED1 (0.10 mm/min, 10 V, 15 g/lit, and 1.5 lit/min), respectively. Finally, the increment of MRR and SR values is mostly dependent on the feed rate of the electrode.

“…Various surface coating techniques are used to reduce wear on machine elements. Many researchers have used methods such as gas tungsten arc welding (GTAW) (Mithun, Sellamuthu & Saravanan, 2018;Chang, Chen, & Wu, 2010;Kumar, Saravanan, Sellamuthu & Narayanan, 2018;Nair, Sellamuthu & Saravanan, 2018;Shanmugasundaram, Arul & Sellamuthu, 2018;Amirsadeghi & Sohi, 2008;Ya-long et al, 2018;Dalmis, Teker & Yilmaz, 2018), manual metal arc welding (MMAW) (Jankauskas et al, 2015;Selvi, Sankaran & Srivatsavan, 2008;Kang, Singh & Cheema, 2017), laser cladding method (Bartkowski & Bartkowska, 2017;Kwok, Cheng & Man, 2000;Yang et al, 2020), thermal spray coating (Kang, Grewal, Jain & Kang, 2012) to reduce wear on machine elements. Among these methods, the GTAW method stands out because of its easy application and cheapness (Shanmugasundaram, Arul & Sellamuthu, 2018).…”

To improve the quality and efficiency of surface coating with the GTAW (Gas Tungsten Arc Welding) method a semi-automatic welding machine was designed based on PLC (Programmable Logic Controller) control. The control program using ladder logic can accomplish system management and control functions. This system could control welding travel speed up to 560 mm/min, measure and saves the current status of the surface temperature at the welding zone via infrared thermometer up to 1600 °C in real-time, has complete automatic fault diagnosis, modify the welding travel speed and save the inputted welding parameters. To evaluate the performance of the designed welding machine, several experiments have been conducted. Optical microscope (OM) and scanning electron microscope (SEM) methods were used for microstructure examinations. In addition, mechanical tests were carried out with the microhardness method. An average of 377.5 HV0.2 microhardness was obtained from the surface of SAE (AISI) 1040 materials used in the experiments to a depth of 1 mm via the coating powders containing 64 wt% FeCrC + 16 wt% FeTi and 20 wt% Ni. The results from the experiments have shown that the designed PLC-based semi-automatic welding machine could be effective in determining the optimum conditions for surface coating and different welding processes.
