Abstract
Abstract Method of high-energy-rate deposition of particulate materials upon a receiving surface whereby the particles are propelled against the receiving surface with sufficiently high kinetic energy to effect bonding between the particles and the surface. The high-kinetic-energy propulsion of the particles is effected by impulsive spark discharge. Apparatus for the repeated propulsion of unit masses of such particles whereby a belt having a series of encapsulated particle masses is passed intermittently between the discharge source and surface, the belt forming one of the discharge electrodes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
A method of cladding and shaping a member comprising: a. supporting a member to be clad adjacent a shaping means of predetermined shape, b. disposing a cladding material on the surface of said member to be clad and providing a working fluid medium above said cladding material, c. generating an intense pressure in said fluid medium against said cladding material at sufficient intensity to cause said cladding material to become molecularly bonded to the surface of said member and simultaneously causing said cladding material and member to be deformed to said predetermined shape.
Claim 2
Independent Claim
93 words
A method of cladding and shaping a member comprising: a. supporting a member to be clad adjacent a shaping means of predetermined shape, b. disposing a cladding material on the surface of said member to be clad and providing a working fluid medium above said cladding material, c. generating an intense pressure in said fluid medium against said cladding material at sufficient intensity to cause said cladding material to become molecularly bonded to the surface of said member and simultaneously causing said cladding material and member to be deformed to said predetermined shape.
Claim 3
Dependent Claim
23 words
A method in accordance with claim 1 wherein said member to be clad is metal and said cladding material is a particulate material.
Claim 4
Dependent Claim
48 words
A method in accordance with claim 1, whereby said intense fluid pressure is composed of a shock wave, said method further comprising directing said shock wave against material disposed on said member to effect the cladding of said member as it is simultaneously deformed to said predetermined shape.
Claim 5
Independent Claim
122 words
A method of cladding metal plate and simultaneously working said plate and cladding to deform same to a predetermined shape comprising: a. supporting a metal plate member to be clad and shaped with one surface thereof in alignment with a forming die of predetermined shape, b. disposing a cladding material against the other surface of said metal plate. c. generating a shock wave and directing said shock wave against said cladding material at sufficient intensity to cause said cladding material to become molecularly bonded to the surface of said plate and to simultaneously deform and change the shape of said cladding material and plate and cause same to conform to said predetermined shape as defined by the shape of said forming die.
Claim 6
Independent Claim
122 words
A method of cladding metal plate and simultaneously working said plate and cladding to deform same to a predetermined shape comprising: a. supporting a metal plate member to be clad and shaped with one surface thereof in alignment with a forming die of predetermined shape, b. disposing a cladding material against the other surface of said metal plate. c. generating a shock wave and directing said shock wave against said cladding material at sufficient intensity to cause said cladding material to become molecularly bonded to the surface of said plate and to simultaneously deform and change the shape of said cladding material and plate and cause same to conform to said predetermined shape as defined by the shape of said forming die.
Claim 7
Dependent Claim
20 words
A method in accordance with claim 4 including generating a plurality of shock waves to clad and deform said plate.
Claim 8
Dependent Claim
36 words
A method in accordance with claim 4 whereby said forming die has a curved shape and the force of said shock wave is operative to cause said clad metal plate to conform to said curved shape.
