The Study on High Temperature Stability Test of Ni/Cr Cold Spray Coating

Abstract

Recently cold spray coating technology was used for many applications in petrochemical business especially for high temperature required section. For this reason, the applied coating must be able to withstand at least 800 °C. The developed Ni/Cr cold spray coating was studied mainly on high temperature resistant property. Ni/Cr with the ratio of 80/20 feedstock powders revealed the highest deposition efficiency and it was selected to use as optimum feedstock powder compositions for the less of experimental study. Finally, it was found that Ni/Cr cold spray coatings reveal excellent thermal stability performance after completed both corrosion and thermal shock tests.
