Ferrography

RSS
Considered to be the most powerful tool in oil analysis, analytical ferrography analyzes the size, shape, color magnetism light effects, and surface details of particles in order to determine the possible causes of abnormal wear to machinery equipment. A ferrogram, resting on a magnetic cylinder, suspends the machine wear debris in a diluted lubricant attracting ferrous, or iron, particles out of the oil. Due to the magnetic field, particles then align themselves along the length of the ferrogram slide. Nonferrous particles and similar contaminants travel downstream across the length of the slide where the magnetic pull strengthens, permanently attaching these particles to the slide to be analyzed under a bichromatic microscope.
