Field Repair of IVD Aluminum Coatings on High Strength Steels Using Kinetic MetallizationTM

R. M. Tapphorn, J. A. Henness, D. Arnold, M. Esposito, Inovati, Santa Barbara, CA

Inovati began using Kinetic Metallization commercially 5 years ago.  The first commercial application was aluminum composite coatings called Al-Trans® to steel telecommunication equipment racks. These coatings provide electrical conductivity coating for high-frequency grounding of telecommunications equipment. Al-Trans® has demonstrated adhesion strength in excess of 10-ksi with corrosion resistance in excess of 5000 hrs in neutral salt spray per ASTM B117. Recently, the US Navy awarded Inovati a SBIR Phase II contract to develop and qualify methods of IVD aluminum field repair on high strength steels.  Performance testing of Al-Trans® (aluminum blended with a transition metal), nano Al-Trans®, and CP aluminum coatings applied to high-strength steels with Kinetic Metallization will be presented in terms of adhesion strength and corrosion resistance. A portable KM system with handheld applicator is used to apply field repair coatings. Inovati is developing techniques for manually rastering the handheld applicator.  Acceptance criteria include uniform deposit thickness and a minimum repair thickness of 1 mil.


Summary: Performance testing of Al-Trans® (aluminum blended with a transition metal), nano Al-Trans®, and CP aluminum coatings applied to high-strength steels with Kinetic Metallization will be presented in terms of adhesion strength and corrosion resistance.
