In this study, the composites with incorporation betel nut powder at three levels (10, 18 and 25%) in Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) matrices having Kevlar Fibres (KF) and Molybdenum Disulphide (MoS2) nano particles in fixed amounts are looked into for their tribological characteristics. The effect of hardness, surface roughness and density was evaluated. FTIR and X-ray diffraction (XRD) studies have been carried out to identify the phases. The effects of load on the slide wear loss and coefficient of friction of the composites were determined using Pin on Disc set up. The wear test pertaining to the betel nut bearing (BNP) composites were compared with those of betel nut free ones i.e. PC/ABS/KF/MoS2. The results revealed that with increase in load, the wear loss increases. Further with increase in betel nut powder concentration from 10% to 25% there is a decrease in wear loss as well as coefficient of friction. The surface morphology of the worn surface were examined using Scanning Electron Microscopy (SEM) which revealed higher plastic deformation, debris formation and furrowing in BNP free systems compared to betel nut bearing ones.

Aisi 316 Stainless Steel

This project investigates on salt bath nitriding process in order to improve the wear behavior of the material. This process increases the hardness of the material. The specimens were nitrided at 580°c on three different timing hours such as 60 minutes, 90 minutes & 120 minutes. A pin on disc machine is used to conduct wear test, so that wear loss can be determined. The specimens are to be magnified by metallographic test like scanning electron microscope. The untreated specimen is used to compare with the nitrided specimen. The best specimen is chosen which determines the life of material & improves the better wear resistance. The hardness of untreated material and nitrided material are compared. The material AISI stainless steel has many unique properties but it lacks wear resistance and hardness because of which it has limited applications. By conducting heat treatment operation, the hardness of the material does not improve, but by conducting case hardening process the hardness of the outer case will be high compared to base metal. If the hardness and wear resistance of the material improves the material can be used in wide range of applications.

Purpose Aluminium matrix composites are subjected to wear as well as higher temperature applications such as pistons, cylinder heads and blocks for car engines. Therefore, it is important to evaluate the performance of aluminium metal matrix composite at elevated temperature. Design/methodology/approach In the present work wear performance of Al-TiC composite with 7.5% reinforcement of TiC powder is carried out at elevated temperature. The composite specimens are prepared with the help of centrifugal casting method to get the large segregation of reinforcement on the outer layer of the composite which is subjected to wear. Taguchi method is used for preparing design of experiments. Findings The wear test is performed on DUCOM pin on disc setup having the heating chamber facility. The results of wear test are analysed with the help of MINITAB 19 software. The results show that temperature has dominant effect on the wear rate. The mathematical model through regression is predicted for wear rate and coefficient of friction. The study of worn-out surface is performed with the help of scanning electron microscope. The micrographs show that the type of wear is changes from abrasive to severe wear and some delamination. Originality/value The experiments are conducted as per ASTM standards. The results give the mathematical equation for wear rate and coefficient of friction at elevated temperatures.

This work investigates Al 6061 alloy with graphite particle impregnated metal matrix composites under dry sliding conditions. The conventional casting techniques were used for preparing the composite material. Experiments were conducted under dry sliding conditions for determining the wear behavior of Al 6061 alloy- Graphite composite material with varying wt % graphite content under different sliding speeds and at different loads. Sliding distance of 250m was commonly used for the wear test. A pin on disc machine was used for conducting the wear test. The test was conducted under atmospheric conditions. Wear rate decreases with increased sliding speed and increases with increasing load. Worn surfaces of the composites were examined through scanning electron microscope. The wear loss of the composite material with 5Wt % graphite was found to be minimum with respect to sliding speeds and loads.

The paper investigates the lubricating properties of epoxidised canola oil. The epoxidation is carried out to decrease the unsaturated bonds present in canola oil. Further, metal dichalcogenide nanoparticles (molybdenum disulphide and tungsten disulphide) are mixed in modified canola oil and their effect on rheological and tribological properties is evaluated. The tribological investigation is carried out on a pin-on-disc tribometer with aluminium alloy and steel as tribopairs. The rheological properties of nanofluids have been studied. It is observed that the modification of the canola oil improves the tribological properties of virgin canola oil. The addition of nanoparticles into the modified canola increases the viscosity of the oil with a 1 wt% concentration of nanoparticles. Further, enhancement in the tribological properties is observed with the addition of nanoparticles. A maximum of 54.6% and 30% decrease in coefficient of friction is observed with the use of tungsten disulphide and molybdenum disulphide nanoparticles, respectively.

<p>In the present work, Al<sub>2</sub>O<sub>3</sub>/A356<sub> </sub>nano composites with different Al<sub>2</sub>O<sub>3</sub> nano sizes (10 and 20 nm) and weight percentages (1 and 2 wt.%) have been prepared using rheocasting technique and followed by hot deformation at 250 °C with different ratios (30 and 40%). Pin on disc wear test was used to study wear behavior of prepared Al<sub>2</sub>O<sub>3</sub>/A356<sub> </sub>nano composites while scanning electron microscopy used to build up the wear mechanism. The results showed that the hot deformed nano Al<sub>2</sub>O<sub>3</sub> /A356 composites have lower wear rate compared with non deformed one. Furthermore, with increasing the particle size and percentage of Al<sub>2</sub>O<sub>3</sub> nano particles, wear rate decreased. The optimal result was achieved at the nano-composite containing 20 nm Al<sub>2</sub>O<sub>3</sub> particles after hot deformation with ratio of 40%. SEM studies of the worn surfaces of nano composites showed that the main wear mechanism was oxidative in conjunction with metallic one.</p>

In this study, acrylonitrile butadiene styrene (ABS) and graphite powder—a solid lubricant—were filled and characterized for friction and wear responses. The fused deposition modeling (FDM) technique was utilized to synthesize ABS–graphite composites. A twin-screw extrusion approach was employed to create the composite filament of graphite–ABS that is suitable for the FDM process. Three graphite particle ratios ranging from 0% to 5% were explored in the ABS matrix. The wear and friction properties of ABS composites were examined using a pin on disc tribometer at varied sliding velocities and weights. As a result of the graphite addition in the ABS matrix, weight losses for FDM components as well as a decreased coefficient of friction were demonstrated. Furthermore, as the graphite weight percentage in the ABS matrix grows the value of friction and wear loss decreases. The wear mechanisms in graphite filled ABS composites and ABS were extensively examined using scanning electron microscopy and confocal microscopy.

This study intends to analyse the coefficient of friction and wear properties of the acrylonitrile butadiene styrene polymer by determining the optimal parameters for 3D printing. The pin specimens were produced using the fused filament fabrication 3D printing. Response surface methodology is used for the multivariate analysis, and Box–Behnken Design is the chosen symmetrical design method. Changes to the dependent variables, coefficient of friction and wear rate, were analysed as a function of the nozzle temperature, layer height and printing pattern. The coefficient of friction and wear rate were measured using a pin-on-disc tribometer. A good agreement between the modelled and measured values of coefficient of friction and wear rate was observed. The study suggests that layer height affecting coefficient of friction and wear rate most significantly. It is determined that a layer height of 0.10 mm and a nozzle temperature of 234℃ using the triangle printing pattern is the optimal set of combination to minimise coefficient of friction and wear rate.
