一、前言水是湿式表面处理(主要是电镀作业)中不可缺少的物质,根据使用目的不同,可分为原料用水、清洗用水及设备冷却水三种。其中除设备冷却水另有要求外,原料用水和清洗用水直接与零件表面接触,对工艺质量影响极大,目前表面处理水质问题已引起普遍关注。在我们的表面处理工作中,主要是处理航空仪表及各种机构的金属弹性敏感元件,其特点是形状复杂、尺寸精度高、同一元件需符合多种特性参数,所以表面质量要求很严,如何改善元件的外观和防锈质量,这是我们多年来所面临的问题。为此,我们从工艺技术和生产 I. Introduction Water is an indispensable material in wet surface treatment (mainly electroplating operation). According to the purpose of use, water can be divided into three categories: raw material water, cleaning water and equipment cooling water. In addition to equipment cooling water otherwise required, the raw water and cleaning water directly contact with the surface of the part, a great impact on the quality of the process, the current surface water quality problems have caused widespread concern. In our surface treatment work, it mainly deals with the metal elastic sensors of aeronautical instruments and various mechanisms. The features are complex shape, high dimensional accuracy and the same component needs to meet various characteristic parameters, so the surface quality is very strict and how Improve the appearance of components and anti-rust quality, which is the problem we have for many years. To this end, we start from process technology and production
