Mineral mill bearing wear monitoring procedure uses pairs of trace element inclusions on surface layers to allow detection in lubricant

摘要

A mill bearing (7) wear monitoring procedure uses different pairs of trace element inclusions (17-23) applied to the bearing surface layers (17-23) so that a measurement of the concentrations of the chemicals present in the lubricant in the oil filter or sump using X ray spectroscopy represents the wear status. Independent claims are included for bearings manufactured using plasma coating and laser processes to apply the chemical coatings to the bearing area.
