低共熔合金粉末氧-乙炔火焰喷焊简称金属喷焊,是将具有各种特性的低共熔合金粉末,经过喷焊枪(如图)的加热,使之熔化或半熔化,并随喷焊枪的高压气流,喷射到被喷焊的工件表面,并在火焰高温的作用下,使已敷在工件表面的那一层合金,与工件本体的金属分子扩散结合,形成一层薄而熔融的呈焊合状态的表面层,以此来达到修复破损零件,或给予零件的耐磨、耐蚀、耐热抗氧化等特性。
Eutectic alloy powder oxygen - acetylene flame spray welding referred to as metal spray welding, is to have a variety of characteristics of eutectic alloy powder, spray gun (Figure) of the heating, so that the melting or semi-melting, and spray gun Of the high-pressure air jet sprayed to the surface of the workpiece being sprayed and flame under the action of the temperature has been deposited on the workpiece surface layer of the alloy with the workpiece body of the metal molecules diffusion combined to form a thin and molten was Welded state of the surface layer, in order to repair damaged parts, or to give parts wear resistance, corrosion resistance, heat and oxidation and other characteristics.
