Abstract
A corrosion-resistant antifriction bearing is disclosed that includes a multi-layer corrosion protection system over a metallic substrate. The corrosion-resistant system may be applied to a single or multiple components of the bearing, including inner and outer rings, bearing elements, collars, and so forth. The system includes a nickel-phosphorous alloy plating layer applied by an autocatalytic process after surface preparation of the protected component. The surface preparation aids in adherence of the nickel-phosphorous alloy plating layer to the substrate. The preparation may include the application of rust inhibitors, liquid vapor honing, acid neutralizing, and so forth. Additional topcoat layers may be applied to the nickel-phosphorous alloy plating layer. These may include a chromate conversion coating and a polymeric topcoat layer. The polymeric topcoat layer, such as polytetrafluoroethylene, may include a UV marker to enable identification of the bearing when placed in service and throughout its useful life.
