Researching Wear Performances of Enging Piston Rings by Activated Thin Layer Technology

摘要

Activated thinlayer technology used to measure wear performances of S1100 type engine piston rings has ome characteristics of high sensitivity, on-line measurementand low radiocativity During continous operation 200h, the wear rate of the measured pistonring is W_c=3.5x10~-2 mum/h. The experimental results accord with lubrication analysis.
