Cold spraying is an inexpensive technique for repairing and restoring industrial application products to replace the damaged part.
The properties of cold spraying for the deposition of materials in the solid state make it an attractive method for repairing / restoration, while maintaining the unique properties of the original components or improving the properties of the repaired components by depositing essential material. The manufacturing of highly complex components such as combustion chambers is simplified by using cold spraying.
