Abstract
Abstract Method of and apparatus for the high-energy rate deposition of particulate materials upon a receiving surface whereby the particles are preheated, preferably concurrently with their formation from a coherent body by subjecting the body to a plasma or electrically fusing the body, and projected against the substrate by intermittent spark discharge, a discharge electrode for this purpose being located behind the particle cloud in the direction of propagation of the particles. Alternatively, encapsulated doses of the particles or masses thereof may successively be disposed in the path of the discharge electrode upon a rotatable turret or disc.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
An apparatus for depositing particulate material upon a receiving surface of a substrate, comprising housing means having a shockwave generator trained on said surface, means between said shockwave generator and said surface for introducing a cloud of particles into the path of a shock wave propagated from said generator toward said surface, means for triggering a spark discharge in said generator to produce said shock wave, the means for introducing said cloud of particles into the path of said shockwave including a fusible body, and means for thermally eroding said fusible body.
Claim 2
Dependent Claim
21 words
An apparatus as defined in claim 2 wherein the last-mentioned means includes electrode means for eroding said body by arc discharge.
Claim 3
Dependent Claim
19 words
An apparatus as defined in claim 2 wherein the last-mentioned means includes a plasma gun trained at said body.
Claim 4
Independent Claim
90 words
An apparatus for depositing particulate material upon a receiving surface of a substrate, comprising housing means having a shock wave generator trained on said surface, means between said shock wave generator and said surface for introducing a cloud of particles into the path of a shock wave propagated from said generator toward said surface, and means for triggering a spark discharge in said generator to produce said shock wave, the means for introducing said particle cloud into said path including a plasma gun forming a plasma stream entraining said particles.
Claim 5
Independent Claim
86 words
An apparatus for depositing particulate materials upon a workpiece surface, comprising electrode means forming a spark-discharge impulse generator trained on said workpiece, a disc of frangible material interposed between said generator and said workpiece and carrying at angularly spaced locations therealong respective masses of particulate material, means for successively aligning said masses of particulate material with said generator, and means for triggering said generator upon each alignment of a respective mass with said generator to deposit the particles of successive masses upon said surface in succession.
