Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus (10, 50) for manufacturing a deposited film (12, 86), and to provide a deposition method thereof and an article (80).SOLUTION: The apparatus (10) includes: a thermal spray gun (16) including a combustion chamber (22); a combustion zone (28); an air injection port (18); a fuel injection port (20); a nozzle (30); and a liquid injection port (34). The combustion zone (28) is positioned between the inlet side (24) and outlet side (26) of the combustion chamber (22). The method includes, among other things, the steps of: providing a fuel and an oxidizer inside the combustion zone (28); initiating combustion inside the combustion zone (28); and directing products of the combustion toward the outlet side (26) to create a combustion product stream. The method also includes the steps of: introducing a feedstock mixture including a feedstock material and a liquid into the combustion product stream to create an entrained feedstock stream; and expelling the entrained feedstock stream from the spray gun through the nozzle to form the deposited film on a surface of the article.
Abstract:
PROBLEM TO BE SOLVED: To surely prevent formation of cracks in a glow plug even after the operation for a relatively long period of time, the glow plug used in e.g. a self-ignition type internal combustion engine, and in particular, the rapidly heated glow plug. SOLUTION: After a body is heated at the recrystallization temperature, the body is deformed at least once again, and the degree of deformation of 20-50% is generated thereby. Then, the body formed of a nickel-based alloy is subjected to recrystallization heating or melt-heating, and/or the melt-heating is performed at the temperature in the range of 1,220-1,330°C.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved method and device for an HVOF thermal spray gun, specifically, a burner design for improving combustion of oxygen and liquid fuel in an interior of a combustion chamber of the thermal spray gun. SOLUTION: In the design, turbulent atomization of the liquid fuel is generated, and the combustion of the combustion chamber interior is improved by using one or more jets as a jetting method for the liquid fuel and oxygen. A burner uses preheated oxygen and preheated fuel to improve vaporization before fuel combustion. COPYRIGHT: (C)2011,JPO&INPIT
