TLDR
Ferrography can be used to detect operational differences between machines operating under apparently identical conditions and to identify wear and contaminant particles and is an effective technique for the condition monitoring of hydraulic systems as discussed by the authors.About:

Active control of hydraulic oil contamination to extend the service life of aviation hydraulic system
TL;DR: In this article, an active method to control oil contamination is proposed instead of the existing passive maintenance techniques that are ridden with problems, which can improve the continuous operation capability of aviation hydraulic systems and extend the intermaintenance period of aircrafts by reducing the contaminant content in oil.

Some current trends in tribology in the UK and Europe
TL;DR: A review of some aspects of current tribology activities in the UK and Europe is given in this article, which is based largely on open literature publications which have appeared within the last four years, and on papers presented at recent tribology conferences, up to July 1985.

The role of particle analysis — a review of ferrography
TL;DR: In this paper, modes of formation of particles can be postulated to correspond with the characteristic mechanism of wear, notably adhesion, cutting and fatigue Chemical and thermal effects must be taken into account and lead to non-metallic particles which are translucent When transported within fluids, particles tend to migrate inwards due to the tubular pinch effect.

Ananda B. Gholap,M. D. Jaybhaye +1 more
TL;DR: In this article, wear particle concentration (WPC) and percentage large-scale particles (PLP) trend shows criticality of the system which can be used to monitor the system.

A method for the study of wear particles in lubricating oil
W.W. Seifert,V.C. Westcott +1 more
TL;DR: The Ferrograph as discussed by the authors is an instrument capable of precipitating magnetic particles ranging in size from a few micrometers down to approximately 20 nm from liquids such as lubricating oils.

Debris examination — a prognostic approach to failure prevention
TL;DR: In this paper, the presence in a lubricant of unique wear particles, easily and quickly revealed by Ferrography and confirmed by electron microscopy and their composition determined by X-ray energy analysis, provides a powerful diagnostic technique for the detection of distress in critical mechanisms and thus prevents catastrophic failure by allowing timely maintenance.

The development of Ferrography as a laboratory wear measurement method for the study of engine operating conditions on diesel engine wear
TL;DR: In this article, the authors used the Severity Index I s to rank the effect of engine operating conditions on wear and found that the severity index is linearly correlated with spectrometric data (iron and lead concentrations in used oil samples).

Ferrography applied to diesel engine oil analysis
TL;DR: Ferrography has to date had restricted usage in the field of condition monitoring of diesel engines as discussed by the authors, and reasons for its restricted use in comparison with other existing techniques such as spectrographic oil analysis.
