Abstract
In this study, the trace analytical technique of instrumental neutron activation analysis (INAA), using the SLOWPOKE-2 Facility at RMC, was used to develop an application termed Quantitative Filter Debris Analysis (QFDA). The preliminary step, which consisted of the quantitative analysis of filter debris samples from CH-124 Sea King helicopter main gear boxes (MGB) for 19 elements associated with engine wear, confirmed that distinct ranges of normal and abnormal wear rates exist in the CH-124 MGB and, more importantly, validated the INAA procedures. The second step, which consisted of the analysis of both oil and filter debris samples from the CF-188 Hornet aircraft engine by the INAA technique and an Atomic Emission (AE) method, confirmed that little useful wear information can be found in the oil of a finely-filtered engine system and demonstrated the potential of QFDA as a means of monitoring wear by analyzing the oil filter debris. What appears to be normal wear rate ranges were identified for the CF-188 Hornet aircraft engine. The potential of monitoring the wear health of oil-lubricated systems using QFDA was confirmed by this investigation.
