化学研磨对彩色显象管电子枪零件性能的影响

Effect of chemical rubbing on properties of electron gun parts of color kinescope

彩色显象管电子枪零件一般由不锈钢材料制成,具有较高的硬度和强度。为解决电子枪零件孔口毛刺难以去除的问题,采用化学研磨工艺进行处理。介绍了化学研磨液的配方、性能及使用方法。研究了化学研磨对零件尺寸、平面度、真圆度、表面粗糙度和耐压值的影响,同时研究了操作温度对研磨后零件表面光洁度的影响。化学研磨提高了电子枪零件的平面度、真圆度和耐压值,降低表面粗糙度。结果表明,化学研磨能改善电子枪零件的表面状况,该工艺简单、成本低、使用范围广。

Electron gun accessories of color kinescope are made of stainless steel which has high hardness and intensity. In view of the problem of burrs existed on orifice surface of electron gun accessories, a chemical rubbing process was developed. Formula, properties and usage of the chemical rubbing solution were introduced. The effect of chemical rubbing on sizes, flatness, evenness, surface roughness and anti pressure property of the accessories was studied. Influences of operating temperature on smoothness of the accessories were also studied. Flatness, evenness, anti pressure property of the accessories were improved and surface roughness thereof was decreased. The results show that electron gun accessories are greatly improved in surface state after chemical rubbing. This process is simple, low cost and has wide applications.
