AbstractThe use of Standing Take-Off Vertical Landing (STOVL) is a key attribute of the Joint Strike Fighter (JSF). While the LiftFan technology to be used on the JSF will provide significant weight savings, excess weight still exists on the JSF. To alleviate this issue, heavy alloy metals (such as stainless steel) are being targeted for replacement with lower density alloys (such as aluminum and titanium). One area for material replacement is the steel inserts that are currently used in bearing housing and flanges. Utilization of aluminum or titanium in this capacity, however, is not currently possible due to fretting and abrasion wear. In this Phase I SBIR program, Infoscitex proposes the development of coating technology that will render aluminum and titanium alloy resistant to fretting wear. A process for protective both aluminum and titanium will be developed, and a range of coating compositions will be investigated.
