Application of Neutron Activity Method in Tribology. Final Report for the Period 15 December 1979-15 June 1983

摘要

A wear diagnostic system consisting of neutron activation analysis, automatic particle counting and ferrography can monitor the wear in auto-engines. The contents of Fe in filter ash and in lubricating oil were determined by neutron activation analysis and can be related to the degree and rate of wearing including the built-in failures of new engines. The engine wear is considered normal if the wear quantities/contaminant ratio does not exceed 30:70. The result of ferrography studies indicated that particles of 30-40 mu m dia. as ferric oxide from oxidative wear tend to increase wear rate significantly. (Atomindex citation 16:078017)
