WebDec 1, 2024 · The tribology characters of DLC-liquid and DLC-grease lubricating coatings were investigated on a rotational ball–on–disk apparatus with applied load of 5 and 10 N under high vacuum ... but MACs greases with additives have a gradual mass loss starting at 247 °C, illustrating that the addition of ZDDP/MoDTC in MACs grease can increase … As mentioned earlier, various authors have suggested different mechanisms by which MoDTC induces high wear to DLC coatings. It was suggested that the formation of hard Mo compounds on the steel counterpart accelerates the wear of the DLC plate when lubricated in oils containing MoDTC [6] and that MoDTC … See more In the first part of the study, experiments were carried out using CI pins and DLC-coated plates for different test duration.

One glaring mistake that contributes to early bearing failure is over/under lubrication. Over and under lubrication is the product of scheduling grease replenishment on a time-based instead of a condition-based schedule, and not knowing how much grease to inject. cost of navien water heater installed
