Gears

Surface finish and functional surface characterization

Bruker’s 3D optical microscopes provide fast, non-contact and gage capable metrology for functional surface parameters relating to the performance of gears, including surface roughness, developed interfacial area, and core fluid retention – each of which influence the performance of a gear in end product use.

Additionally, 3D optical microscope technology allows for study of lubricant and corrosion inhibition via automatic pitting identification and characterization and time studies of data in a non-contact and highly accurate manner.

3D optical profilers also characterize wear volume and surface finish changes associated with tribology. Surface characterization is accomplished in a fast, non-contact, non-destructive manner for high-throughput efficiency.

The tight tolerances in manufacturing of gears and the component cleanliness code require the understanding of contamination during the manufacturing process. Crystallographic analysis of materials used in the manufacturing of gears aids in the understanding of material reaction to stress and temperature. Both Bruker's EDS and EBSD on SEM systems (combined with particle analysis) and the Micro-XRF instruments offer detailed analysis of particulate matter.

Another important aspect in the manufacturing of gears is the quality control of numerous protective coatings. Coatings can be evaluated with our layer thickness analysis package for the Micro-XRF instrument range.
