Method description:
A method involving the phenomenon of atomic emission spectroscopy (AES). The excitation of elements in the sample takes place in an electric arc (7,000-8,000 °C) generated between a rotating disk electrode and a rod electrode. From the amount of energy emitted, of the individual elements, the instrument defines their concentration.
Interpretation of results:
In the test, particles smaller than 5 μm (particles “dissolved” in oil) are determined. The determined elements are presented in the report as wear metals, additives and impurities.
The level and course of concentration of individual metallic elements, and their correlation with the metallurgy of the lubricated components, answers the question of whether wear processes are too intensive in the equipment.
The level of additives indicates the degradation processes of the additives and/or the correctness of the lubricant used. The level of contaminant-defining elements can provide information about leaks and the ingress of contaminants from the environment or side systems.
