Detecting Galling and Other Forms Of Catastrophic Adhesion in Tribotests in Real-Time
Tribotests are used to evaluate the performance of lubricants and surface treatments intended for use in industrial applications. They are invaluable tools for lubricant development since lubricant parameters can be screened in the laboratory with only the best going on to production trials. One of the most important applications of laboratory lubricant screening is for adhesive wear (e.g. galling). Process failure from this form of wear is not predictable and as a consequence production trials might not reveal the ability for a lubricant to protect against it. When adhesive wear occurs it is typically catastrophic leading to unscheduled downtime [1].
