As you know, adhesive wear is one of the most common types of wear mechanisms. Perhaps you can attest to this within your own application? You’re aware that when stresses are low and temperatures are high, VSI’s are generally susceptible to little wear, but, when lubrication is taken away, the risk for wear increases tremendously. Unlike abrasive wear, adhesive wear occurs when high pressures, temperatures, or loads cause two metal surfaces in a sliding contact bond to immediately tear apart. The materials on the point where the two surfaces interact, being much stronger than surrounding areas, cause the particles to be detached from one and transferred to the other. Needless to say, this is something that you want to avoid. Luckily, there are many ways to get around this issue. The most common way, and what we recommend most often, is that you consider Plint testing your material pairings.
