Improvement in frictional behaviour of SAE 15W-40 lubricant with the addition of graphite particles
Publication date: Available online 9 September 2019Source: Materials Today: ProceedingsAuthor(s): Vineet Sharma, Rajat Joshi, Himanshu Pant, Vipin Kumar SharmaAbstractThe present paper discusses the use of graphite particles in the lubricant for enhancing the friction properties of lubricant. Graphite particles were produced using the ball milling methods and mixed with multi-grade SAE 15W-40 lubricating oil using a magnetic stirrer and ultrasonicator. The graphite mixed lubricant was tested for its frictional behaviour using a linear reciprocating tribometer. Experiments were performed at three load values with constant s...

Prediction of noise, vibration and exhaust gas emission characteristics using palm oil in a four stroke diesel
Publication date: Available online 19 September 2019Source: Materials Today: ProceedingsAuthor(s): V. Velmurugan, C. Naveen kumar, V. Paramasivam, S. ThanikaikarasanAbstractIn the today’s world of transport usage by passenger and the driver, Noise and vibration of the diesel engine vehicles are an important issue to be addressed by the automotive industries. This issue is not only makes the occupants fatigue but also increases the environmental noise and smoke pollution from the Diesel engine vehicle. As the usage of the diesel fuelled passenger cars are increasing due to its more mileage, better performance efficiency. ...

Mechanical and energy-absorption properties of schwarzites
Publication date: February 2020Source: Carbon, Volume 157Author(s): Levi C. Felix, Cristiano F. Woellner, Douglas S. GalvaoAbstractWe investigated through fully atomistic molecular dynamics simulations, the mechanical behavior (compressive and tensile) and energy absorption properties of two families (primitive (P688 and P8bal) and gyroid (G688 and G8bal)) of carbon-based schwarzites. Our results show that all schwarzites can be compressed (with almost total elastic recovery) without fracture to more than 50%, one of them can be even remarkably compressed up to 80%. One of the structures (G8bal) presents negative Poissonâ€...

Effect of load on the friction and wear properties of aluminum hybrid composite/chromium plated chrome steel tribopair under boundary lubrication conditions
Publication date: Available online 20 December 2019Source: Materials Today: ProceedingsAuthor(s): Pranav Dev Srivyas, M.S. CharooAbstractFriction and wear loss are the main reason that contribute to the failure in the IC engine components. This emerges the demand for the light weight, low friction and wear resistant material to enhance the efficiency and to reduce the emission problem in the IC engine components. In this concern, tribological test are performed on the hybrid aluminium matrix composites (Al–Si/Al2O3/GNP) composite fabricated using non-conventional rapid Spark Plasma Sintering (SPS) against chromium plated...

Effect of compression ratio on a single cylinder diesel engine operated with Ternary fuel
The objective of this research is to evaluate the characteristics of an engine by using diesel–biodiesel-ethanol (Ternary fuel) into the present VCR (Variable Compression Ratio) single-cylinder four-stroke water-cooled diesel engine. In this investigation, palm oil is taken as biodiesel. The world needs biodiesel due to the deficiency of fossil fuels. The best choice is selecting the biodiesel and ethanol because they are available from the renewable feedstock, non-toxicity to the environment and it is eco-friendly. In blending stage B30 as a blend chosen because it contains 70% of diesel, 20% of biodiesel as palm oil an...

Comparison of optical microscopy and optical coherence tomography as quality assurance methods for evaluating lubricious hydrophilic coatings surrounding catheter shafts
AbstractCardiac catheters are a vital tool in medicine due to their widespread use in many minimally invasive procedures. To aid in advancing the catheter within the patient's vasculature, many catheters are coated with a lubricious hydrophilic coating (HPC). Although HPCs benefit patients, their delamination during use is a serious safety concern. Adverse health effects associated with HPC delamination include pulmonary and myocardial embolism, embolic stroke, infarction, and death. In order to improve patient outcomes, more consistent manufacturing methods and improved quality assurance techniques are needed to evaluate ...
