Cold spray (CS) is a new coating technology for the production of high quality metallic based coatings. This process involves the deposition of metallic layers and structures from propelled fine powders using a high-speed gas jet flow without melting. Low-pressure type CS process, which consists of small and compact equipment, is expected to be used for on-site repairing application. In this work, the possibility of the repair for zinc plating by low-pressure type CS technique was discussed. We have successfully obtained thick (mm order) Zn deposition by low-pressure type CS technique. Moreover, from the investigation results of environmental resistant properties, it may be considered that CS technique have high possibility to apply the repairing application for the Zn plating.
