20110229649 | SUPERSONIC MATERIAL FLAME SPRAY METHOD AND APPARATUS - A method of forming a coating deposits a material onto a substrate with high velocity thermal spray apparatus. The method comprises the steps of mixing of an oxidizer gas and a gaseous fuel in the mixing unit, igniting and combusting the oxidizer and gaseous fuel mixture in the combustion chamber, feeding products of combustion to the accelerating nozzle, introducing selected spraying material into accelerating nozzle to form a supersonic stream of hot combustion product gases with entrained particles of spray material, and spraying at high velocity onto a surface positioned in the path of the stream at the discharge end of the nozzle; and forming a non-clogging convergent-divergent gas dynamic virtual nozzle (GDVN) in the accelerating nozzle by annularly introducing a coaxial gas flow, through a narrow continuous slot of circumferential ring geometry in the vicinity of the entrance to the diverging outlet bore of the accelerating nozzle. | 09-22-2011 |

20100215864 | METHOD OF HIGH INTENSITY COOLING OF PERMEABLE BURNER BLOCK OF A FLAME SPRAY APPARATUS - A method of forming a coating deposits a material onto a substrate with high-velocity thermal spray apparatus. The method comprises the steps of mixing of an oxidizer gas and a gaseous fuel in the mixing unit, igniting and combusting the oxidizer and gaseous fuel mixture in the permeable burner block to form products of combustion, feeding products of combustion to a discharge nozzle passage, introducing selected spraying material into the products of combustion to form a stream of particles that are accelerated and heated by the products of combustion in the nozzle; and applying liquid fuel to structural components of the permeable burner block for enhanced cooling of the structural components. | 08-26-2010 |
