一、引言火炮引信中的许多零件采用铝材制作,为减少加工余量,多数零件用冷挤、冲压成型、再转机械加工.成品零件残留了油污和冷挤时的润滑剂,影响零件外观和装配.必须用化学的方法进行抛光和酸洗,使零件光亮洁净.但经冷挤的零件在冷挤时由于金属内部错位,造成了许多疏孔,零件在酸洗和化学抛光的过程中,这些疏孔很容易有酸碱滞留,影响零件的防腐,用机械的方法这些酸碱是甩不出来的,必须用化学方法对抛光后的零件进行防腐处理.
I. INTRODUCTION Many parts of the artillery fuse are made of aluminum, in order to reduce the machining allowance, the majority of parts are cold-extruded, press-formed, and then machined. The finished parts are left with oil and lubricants when cold-extruded, affecting the appearance of the parts And assembly.Should be chemically polished and pickled to make the parts bright and clean.But the cold extrusion of parts due to metal extrusion within the cold due to misplaced, resulting in a lot of porosity, the parts in the pickling and chemical polishing process , These sparse holes are easy to have acid and alkali retention, affect the parts of the anti-corrosion, with the mechanical method of these acid-base is not thrown out, you must use chemical methods for the polished parts corrosion treatment.
