1241 Evaluation of mechanical properties of carbon steel on cold spraying coating
Details
Carbon steels have been using in many structures, because the steels have excellent workability, affordability, and low price etc. However, it can be obtained corrosion damage or cracking on aging degradation. Cold spraying, which is a new maintenance technology, attracts attention recently. Though, it's difficult to make high carbon steel coatings by cold spraying, because high carbon steel includes much carbon. As a result, these are not many studies of cold sprayed carbon steels. In this study, dense and thick coatings of carbon steels by cold spraying was obtained, High carbon steel powder and mixed powder, which is mixed high carbon steel with mild steel powder were used. As a result, denser carbon steel coatings were obtained. And also, the coating hardness was higher than that of bulk steels.
