Dezhou Xincheng meticulously tested the entire process of this new oil film formation using a four-ball machine across pressure stages, resulting in a friction and wear scar curve. When the oil film stabilizes, this curve remains steady. However, during the chemical oil film formation stage, extreme pressure additives in the oil undergo intense reactions, leading to lubrication instability and causing fluctuations in the curve. This stage is unavoidable, but the intensity and duration of these linear fluctuations can be improved by selecting appropriate extreme pressure anti-wear additives.
