Possibilities of application PVD coating nACRo4 deposited on high contact ratio gearing in interaction with the conventional and eco-friendly lubricant

The submitted article deals with the issue of the application of the PVD coating nACRo4 deposited on the High Contact Ratio gearing made of 16MnCr5 material in interaction with the conventional PP 90H lubricant and biological Biogear S150 lubricant. Experimental tests were carried out on an FZG test rig with closed performance flow, followed by measuring of the surface roughness change. In experiment, we followed the STN 65 6280 norm for FZG scuffing tests, from which we gained load values for different load levels. The results of experimental tests were statistically processed and, on basis on them, relations were established between surface roughness and load level for both used lubricants.
