Eliminating Hexavalent Cr Emissions in Thermal Spray

This study details efforts to develop the next generation of high performance thermal spray alloy wires which are Chromium free, thereby resulting in zero Cr6+ emissions. In order to meet these objectives high throughput computational metallurgy was employed. The initial results have shown that next generation alloys can be developed to meet or exceed the performance of incumbent Cr- bearing alloys currently in service, and that the future of Cr- free alloys is on the horizon.
