Abstract: A wind-turbine gearbox system includes an input gear stage having mating gear surfaces finished to a surface roughness of less than 0.25 micron and at least one bearing supporting the input gear stage. A lubrication circuit is arranged to deliver lubricant to the input gear stage and the bearing during operation of the wind-turbine and includes an inline filter for removal of particles of less than 2 micron from the lubricant prior to delivery. A lubricant for use in the system may have a relatively low viscosity compared to conventional wind turbine gearbox lubricants.

Abstract: A highly reactive conversion coating chemistry is used during CAVF processing of high hardness steel alloys such as AMS 6509 and AMS 6517 steel alloys. This chemistry produces a hard, thin, black conversion coating that is not fully rubbed off by the media during the CAVF process. Distressed material regions on the surface of the alloys are not susceptible to forming the conversion coating and remain white. Visual inspection for the presence of such regions is facilitated.
