MTM ECR Option

Part code: PCS-002687


An electrical potential is applied to the ball.


During a test, the lubricant between the specimens is normally non-conductive, therefore the ECR signal (value between 0 and 100%) indicates the surface interaction between the specimens. This is particularly useful when studying additive performance in the mixed and boundary lubrication regimes. The ECR signal has proven valuable in the study of scuffing by detecting the sudden film collapse at the onset of scuffing.
