method description:
The previously prepared sample in the consistency profile test on the GTA apparatus – the grease film on the substrate formed in matrix extrusion – is analysed using a vision system. Thanks to the advanced recording system and the computational algorithms developed, a classification of the degree of lubricant contamination is obtained by determining the concentration of particles (in mg/g in sizes ˃10 µm, ˃25 µm, ˃80µm) and the percentage characterisation of particles of size ˃25µm with a classification of their formation processes (e.g. abrasive wear, adhesive wear, fibres).
