Influence of Surface Finishing on the Load Capacity of Coated and Uncoated Spur Gears


PVD/PECVD coatings have been proven to increase the pitting and scuffing resistance of materials. However, due to concerns that the application process of PVD/PECVD coatings leads to a reduction tooth root strength, as well as high production costs, the use of these coatings have not been adopted by the gear industry. The aim of this work is to investigate and determine the influence of surface finishing processes, specifically the impact of PVD/PECVD coatings applied using an optimized coating process, on the pitting load capacity of gears.
