Tribological Effects of Mineral-Oil Lubricant .

Use of biodiesel produces engine oil dilution because of unburned biodiesel impinging on cold walls of the combustion chamber, being scrapped to the oil pan, and leading to changes of oil friction, wear and lubricity properties. In this paper, mixtures of SAE 15W-40 oil, which were contaminated by known percentages of the biodiesels from canola oil, peanut oil, soybean oil, and chicken fat ...

More importantly, the roughness of the disks differed between POF Tests 1 and 2. This difference was captured, in that roughness was included as a factor in the model. Second, this study focused on the effect of albumin on wear and friction and ignored the effect of other proteins (e.g., gamma-globulins) on wear, friction, and scar morphology.

Lubricant Contaminants Limit Gear Life | Gear Solutions .

Lubricant cleanliness refers to the absence of contamination. 1 Microscopic particles are the most harmful form of contamination in lubricants. They can irreversibly damage gear and bearing surfaces, shorten the service life of equipment, and cause unexpected breakdowns. 1-4 The concentration of particles in new “as supplied” drums of lubricant can differ by as much as a factor of 1,000 ...

The effect of soot and diesel contamination on wear and .

The effect of oil contamination and oil degradation on friction and wear of engine oil pump are addressed in this paper. It provides a summary of an experimental study on the effects of oil contamination and oil degradation on tribological performance of a Variable Displacement Vane Pump (VDVP); a particular focus is on the vane-rotor contact.

ester temperature effect on wear and friction characteristics. Zulkifli et al. [7] studied the wear prevention characteristics of a palm oil-based TMP (trimethylolpropane) ester as an lubricant and show that 3 % palm engine oil had the lowest WSD and COF with compared to other lubricants. Resul et al. [8] studied the temperature

Effect of Contamination on the Friction and Wear of .

Abstract. The friction and wear mechanisms of water-based fluids consisting of various types of carboxylic acids have been systematically investigated using a ball-on-disc tribometer on a super duplex stainless steel under boundary lubricating conditions.

Friction and wear of bearing material under water .

Figure 3: Effect of water contamination on friction torque 3.3 Wear Scar Diameter Figure 4 shows the effect of water contamination on wear scar diameter. It was found that at 10% and 20% of water contamination resulted in higher wear scar diameter. The influence of wear scar diameter is depending on the operating time and the type of oil [8].

Anti-Wear & Friction Modification | MotoTribolo

ZDDP is a very common anti-wear additive that usually does not have much, if any, effect on friction because it’s own coefficient of friction is similar to metals. Conversely, MoDTC often does have a lower coefficient of friction so it reduces wear and friction a the same time.
