Ferrography - Wikipedia
网页Ferrography is a method of oil analysis used to inspect the severity and mechanisms of wear in machinery. This is achieved by separating ferrous debris from lubricating oil by use of a magnetic field with an instrument called a ferrograph, the result is then examined with microscopy. A trained analyst can then diagnose faults or predict failures.
