Cold spray roll is a kind of equipment using cold spray technology, which is mainly used for coating on metal or alloy surface. Different from traditional thermal spray technology, cold spray technology is a low-temperature spraying method. It can spray powder material at high speed onto the surface of workpiece without heating the substrate, thus forming a dense and strong coating. This technology can not only avoid thermal damage, but also achieve a relatively fine coating. It is widely used in repair, modification, and enhancement of material performance. The spray gun is the core component of the cold spray roll. It delivers and accelerates the spray powder through high-speed airflow. It is equipped with multiple gas nozzles and powder feed ports to ensure the full mixing and acceleration of airflow and powder during the spraying process. The gas supply system provides power to the cold spray roll through compressed air or other inert gases. The gas supply system needs to ensure the stability and pressure of the gas to ensure the smooth progress of the spraying process. The fine control system of the cold spray roll equipment can adjust parameters according to the characteristics of different workpieces, adapt to the spraying needs of workpieces of various sizes and shapes, and achieve high-quality spraying effects.
