美国通用电气公司发明了一种制造异型金属零件的新工艺,即用喷雾器将金属“雾”喷入铸型,金属“雾”与铸模内表面一接触马上变硬。“铸件”是一层接一层形成的,直至达到所需要的厚度。这样制成的金属零件精度极高,内部不会形成砂眼,基本上不需要对它作进一步的加工。喷雾器(金属喷涂枪)里装入金属粉末,粉末同来自电弧室里形成的气体—等离子体 The United States General Electric Company invented a new process for the manufacture of shaped metal parts, that is, the metal atomizer spray into the mold, the metal “fog” and mold the inner surface of a contact immediately hardened. “Castings” are formed one after another until the desired thickness is achieved. Made of metal parts with high precision, the internal will not form trachoma, basically do not need it for further processing. Sprayer (metal spray gun) into the metal powder, powder from the arc chamber with the formation of gas - plasma
