Abstract:  
A new method of surface hardening - gas detonation technology - is a subject of this paper. A main idea and a principle of operation of device in which a controlled explosion of gas mixture propane-butane with oxygen is used to impart proper speed to powdered materials used for hardening. It became possible to control the speed of particles depending on the chosen technological parameters. The effect of the sprayed particles on structure of surface layer of material and also on change of residual stresses has been discussed. Possibilities of practical application of this method in industry have been presented.
