A method of bonding powdered material to a surface comprising placing at least one layer of powdered material onto a support of ductile material, positioning a surface to be coated by the powdered material in facing spaced relation with the powdered material and placing an explosive charge on the support on the surface thereof opposite the powdered material. The explosive charge is then detonated to produce acceleration of the support and the powdered material thereon towards the surface to be coated to cause impact of the powdered material with the surface to be coated and welding thereof. The detonation of the explosive charge proceeds along the length of the charge to progressively bring the powdered material into impact contact with the surface to be coated. The speed of detonation of the explosive charge is less than the speed of sound in the powdered material or support. |
