Study on New Technology for Preparation of Tungsten Coating by Detonation Gun Spraying Based on Blast Loading of High Explosive

Detonation gun spraying was a focus in material surface processing research.The existing detonation gun spraying was summarized,and a new alternative method for coating preparing on the base of existing technology was put forward,that was to say,detonation gun spraying based on blast loading of high explosive.In this paper,the theory of detonation gun spraying using explosive energy were described in detail,and the advantages and disadvantages were analyzed in comparison with detonation gun spraying.And tungsten coating was prepared by the new technology.Through the detection of tungsten coating,it showed that the tungsten coating has better uniformity and compactness and heat loss was small.Also the application of the technology were pointed out.
