ferrography

[fe′räg· rə·fē]
(engineering)
Wear analysis of machine bearing surfaces by collection of ferrous (or nonferrous) wear particles from lubricating oil in a ferrograph analyzer; the method can be applied to human joints by collecting fragments of cartilage, bone, or prosthetic materials from synovial fluid.

Some of the metals are present in the form of fine particles--with analytical ferrography, ferrous wear particles are always found.
With oil lubricated machines accounting for such a large proportion of the maintenance effort it's no surprise that the relationship between lubrication and mechanical wear is now used as a tool by services to inspect and monitor conditions within machines and, with the development of the latest analytical techniques combining the principles of ferrography and spectroscopy, to predict future maintenance requirements.
In ferrography, a metal particle detector with a magnet is employed; it is a very sensitive technique for detecting and sizing wear particles from ferrous components.
With oil lubricated machines accounting for such a large proportion of the maintenance effort it's no surprise that the relationship between lubrication and mechanical wear is now used as a tool by services such as Castrol's 'Predict' to inspect and monitor conditions within machines and, with the development of the latest analytical techniques combining the principles of ferrography and spectroscopy, to predict future maintenance requirements.
