... and pressing of the three balls were done against the ball at top which rotates at the chosen velocity at the same time in which the three balls get pressed. Figure 1 presents the tribotester machine of four balls while Figure 2 shows the significant constituents that represent the oil cup assemblage, collet, and ball bearings. Cleaning the constituents' exteriors was done with acetone in advance of conducting any test. ...

It has been demonstrated in a variety of experimental studies that mineral oil (MO) and vegetable oil (VO) can be blended in different ratios to improve insulation properties; however, the mechanisms underlying this phenomenon remain unclear. In this study,...
