摘要： PURPOSE: An explosive spray coating method is provided to simultaneously spray coat mixed alloy of the low melting point and the high melting point by selectively falling explosive temperature by nitrogen. CONSTITUTION: A certain amount of nitrogen gas is injected to the inner part of a cylinder by using a scavenge valve. Oxygen and acetylene gas are supplied to form a fuel(30) gas part diluted by nitrogen on the front end of the cylinder(5). A non-diluted fuel(29) gas part is formed on the rear of the diluted fuel gas part. A spray coating is performed to make the fuel parts selectively exploded when supplying the mixed alloy powder. By using the scavenge valve having larger diameter than that of a nitrogen valve(31), the fuel is mixed with the nitrogen gas effectively in a short time and the explosive temperature is decreased. Only low melting point alloy is fused half by the diluted fuel. The high melting point alloy is selectively coated by the non-diluted fuel by hot explosive power.
