Abstract:

ABSTRACT: Amorphous composite (AC) coatings are an alternative coating material to the existing High Velocity Oxygen Fuel (HVOF) Tungsten Carbide Cobalt and Tungsten Carbide Cobalt Chrome (WC-Co and WC-Co-Cr). The purpose of AC coatings are to eliminate spalling on Low and High Strength Steel (LSS and HSS) at, or greater than component design loads. These coatings could potentially be used on other materials that see high bending stresses such as Titanium and Precipitation Hardened steels commonly utilized in aircraft structure. The SBIR Phase I work completed by Engineering and Software System Solutions, Inc. (ES3) focused on finding a HVOF coating more resistant to spallation when subjected to high-bending stress loads. Initial Phase II testing validated the AC coatings on LSS material used in aircraft, landing gear, propeller and engine applications. Subsequent Phase II testing of a HSS material is studying the coatings on HSS, type 300M (280-300ksi), used on various aircraft components encountering high stresses and bending loads. The Phase II.5 transition plan will focus on additional testing identified during Phase II; including testing for 6Al-4V titanium and 13-8Mo PH stainless steel alloys, applying the amorphous composite coatings on Dem/Val parts, creating fixturing, robot programs, adapting the repair documentation to the targeted components, and training. BENEFIT: Research conducted for chrome plating replacement with HVOF AC coatings on LSS and HSS, as well as titanium and PH steels are primarily used on aircraft, landing gear, engine and propeller system components. Benefits will be similar for all aircraft usages for replacement of chrome plating where spallation concerns for high stress loads, especially under bending occur where current wear and corrosion protection needs exist. The following lists benefits ES3 expects from use of HVOF AC coatings in lieu of chrome plating based on both industry and in-house research: Improved wear resistance Improved corrosion resistance Increased fatigue life Improved thermal properties Eliminated hydrogen embrittlement Improved process time Increased service life Improved environmental concerns Utilize same grinding wheel as HSS substrate for machining Reduced spallation Reduced cost of AC powders compared to common HVOF WC-Co and WC-Co-Cr powders
