Analytical Ferrography
Definition:
Analytical Ferrography can predict potential equipment failures or be an effective tool in determining the root cause of failure. AF is a qualitative, rather than quantitative, analysis that provides digital imagery of the actual particles present. Powerful magnets trap the ferrous particles. Non-ferrous particles and other wear debris particles are then deposited randomly on slides for microscopic analysis. Particles are analyzed based on metallic or non-metallic, alloy via heat treatment, shape, size, color, and if possible, source.
Standard Test Method Used:
POLARIS Laboratories® Method
Reporting Measurement:
Picture - digital imagery at 100x, 500x or 1,000x with severity levels 1-4 assigned to each wear or wear debris category
Amount of Sample Needed:
2 mL
Test Limitation:
Results are subjective based on the knowledge and experience of the data analyst and dependent on the detail of information provided with the sample.
