“…In addition, the sample fluid will be heating up to 75°C and this experiment is going to run in 60 minutes. Table 1 shows the specifications of balls that been used in this study [33]. Other that Fourball Tribotester, 3D Surface Measurement System (Alicona) with the usage of the optic IFM G4 10x have also been used in this research in order to measure the wear scar diameter that is being produced at the three balls at the bottom.…”

This study presents the tribological characterisation of biofluid that uses plant-based oil namely sunflower oil and olive oil that has been blended with hyaluronic acid as an additive. Plant-based oil is a type fluid that is not harmful to humans and the hyaluronic acid helps the based fluid in absorption shock and distribution of forces. This project aims to measure the performance of this biofluid as an artificial synovial fluid in terms of its coefficient of friction, frictional torque and the wear scar diameter produced. Three different composition volumes of hyaluronic acid were used which are 0%, 5% and 10% in the fluid sample. This sample of biofluid is tested by using four ball tribological testing under one of the conditions which was wear preventive condition. To obtain the coefficient of friction and frictional torque for the biofluid by using the 3D Surface Measurement Systems, we measure the wear scar diameter produced at the ball bearings. The results acquired for this study are the average coefficient of friction and frictional torque that were directly proportional to the volume composition of additives. However, for the average wear scar diameter, it depends on the suitability of volume additives that have been added. Pure sunflower oil has the lowest coefficient of friction which is 0.065940. While, for average wear scar diameter, olive oil with 10% hyaluronic acid recorded the lowest value which is 0.64828mm. It shows that pure plant-based oil has the best lubricant ability which is producing lower coefficient of friction and frictional torque compared to it going to be blend with hyaluronic acid. This result of this project might give benefits to the medical engineering nowadays that related to the case that need the usage of artificial synovial fluid.

“…From the two Figures 5 and 6 could be observed that the values of the friction coefficient began decreasing gradually over time and also noted that the values of friction coefficient of vegetable fluids are lower at high load as in the case of normal load 20 kg., which was 0.0159 and 0.0230 for the corn and mineral fluid respectively, this result can be attributed to the long chain fatty acid and the esters which are known as active anti-friction materials [18][19][20][21][22][23][24][25].…”

Low toxicity, high biodegradability, renewability and high viscosity index of the plant (vegetable) oils made it have immense potential to replace the mineral cooling fluids. This study aims to evaluate the wear and friction behaviour characteristics of the corn fluid as a renewable bio-fluid resource. Base on the ASTM G-99 standard, behaviour characteristics of fluid were examined in terms of kinematic viscosity, friction force, coefficient of friction, wear scar diameter, and flash temperature parameter. Each experiment was do during one hour and 800 rpm as a rotation speed of disk and under four different loads 5,10,15,20 kg using the ball on disk tester, the (Mobil hydraulic fluid 424) used as a mineral cooling hydraulic fluid sample for compared the results. Based on the results, it was found that under low loads (5 and 10kg) the performance of vegetable fluid (corn) is better than the mineral hydraulic fluid (463.38 & 469.84 µm under 5kg and 567.1&593.74 µm under 10 kg respectively), also the values of friction coefficient of vegetable fluids were lower under high load as in the case of normal load 20 kg., which was 0.0159 for the corn and 0.0230 for the mineral fluid. Finally, it is concluded that the corn fluid could be an alternative renewable working cooling fluid due to its adequate performance.
