金属零件的处理在夜视器件制造工艺中,对金属零件的处理方法,常用的有以下四种。 1.化学清洗法这种方法一般是:(a)用强酸(盐酸、硝酸、硫酸、氢氟酸等)和强碱(氢氧化钠、氢氧化钾等)来去除金属表面沾污的杂质及腐蚀其表面的氧化物,使酸或碱与金属表面氧化物起化学反应,生成新的化合物,脱离金属表面,从而达到去除金属表面氧化物的目的,使零件表面呈现本来的金属 Metal parts processing In the night vision device manufacturing process, the processing of metal parts, commonly used in the following four. 1. Chemical cleaning method This method is generally: (a) with strong acids (hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, etc.) and alkali (sodium hydroxide, potassium hydroxide, etc.) to remove metal surface contamination of impurities and Corrosion of the surface of the oxide, the acid or alkali and the metal surface oxide from the chemical reaction to generate new compounds, from the metal surface, so as to achieve the purpose of removing oxides on the metal surface, so that the original surface of the metal parts
