This paper summarized the processing principles and characteristics of the cold gas dynamic spray(cold spray) technology. It emphasized to discuss the coating deposition mechanism and the parameters which influenced the critical velocity of the particles and the coating quality. It is believed that using the proper parameters in the coating process is vital for getting high quality coating, improving the structure of the spray gun, fabricating functional and composite coatings are considered as the main directions of the cold spray in future.
