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.
