| Abstract Scope |
Cost effective alternatives to electroplated hard chromium (EHC) that can provide comparable performance, reduce compliance burdens, and address worker safety concerns have been sought by the United States Air Force (USAF) for nearly 20 years. During these investigations, environmental, safety, and health regulations have become more stringent. As a result, implementing EHC alternatives for complex geometries continues to be a need. To address this need, work has been performed to fully optimize and test electrolessly deposited nickel-phosphorus coatings with occluded silicon carbide (SiC) particles and electrodeposited cobalt-phosphorus (Co-P) coatings with occluded SiC particles. More recently, a newly formulated nano-cobalt phosphorus coating with proprietary occluded particles has been included in the investigation. This presentation will discuss the results that were obtained to date to address EHC replacements for landing gear applications. The composite coating properties are being compared to those of EHC as well as a benchmark coating, nanostructured Co-P. |
