在连接器产品设计中,需要对形状复杂的不锈钢玻璃封接组件进行表面处理,使零件表面达到镜面光亮效果,才能在后续电镀过程中更好地保证产品的性能。根据实际生产过程中的需求,研究了不锈钢玻璃封接组件电镀前表面处理达到镜面光亮效果的工艺过程,探索出一种新型环保不锈钢化学处理液,讨论了溶液各组分和温度、处理时间等工艺参数的影响。通过实验和生产验证,该不锈钢玻璃封接组件镜面化学处理液的最佳工艺条件为:40 m L/L硫酸,80 g/L添加剂XSY,θ为80℃,t为30~50 s,其表面可达到镜面般光亮,且封接玻璃表面无裂纹,保障其表面在电镀过程中具有良好的镀层结合力和表面质量,满足了设计对产品的性能要求。 相似文献

彩色不锈钢色彩呈不连续光谱色原因的探讨 总被引:2,自引:0,他引:2
彩色不锈钢的色彩是其表面反射光与通过表面膜层折射光的干涉色,通过对蓝色、金黄色、红色、绿色、柠檬黄色和浅红色等六种彩色不锈钢试样的俄歇能谱(AES)检测,证明随着膜层厚度的变化,其结构组成也发生了变化,导致其折射率的改变,这是引起彩色不锈钢色彩呈不连续光谱色的主要原因,同时也分析了其它引起这一现象的一些因素 相似文献

热处理与加工成型工艺对双相不锈钢流动腐蚀的影响 总被引:1,自引:0,他引:1
研究了热处理与加工成型工艺对双相不锈钢在流动 3 .5 %NaCl溶液中流动腐蚀的影响。结果表明 ,随着固溶处理温度Ts 的升高 ,锻压双相不锈钢的耐蚀性降低 ;随着时效强化时间的延长 ,锻压双相不锈钢的硬度增大 ,耐蚀性有所提高 ,但是锻压双相不锈钢的耐流动腐蚀性能与它的硬度并不存在一致对应的关系。铸造双相不锈钢在流动 3 .5 %NaCl溶液中的腐蚀速度随着介质流速的增大而缓慢上升 ,高流速条件下 ,其表面发生了严重的坑、点等局部腐蚀。固体颗粒的加入 ,促使其流动腐蚀加剧 ,且存在一个使腐蚀速度急剧上升的临界流速值 ,其流动腐蚀过程主要受阳极过程控制 相似文献

The adhesion strength and water resistance of stainless steel and adhesive resin composites determine the long‐term performance of wires and cables; however, adhesion at stainless steel interfaces is difficult. Herein, we prepared ethylene acrylic acid/linear low‐density polyethylene (EAA/LLDPE) blends with good mechanical and adhesive properties. Silane was anchored to the surface of stainless steel. The effects of silane functionalization on the adhesion surface were investigated by X‐ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The reaction mechanism between the stainless steel, silane, and EAA/LLDPE revealed adhesion was optimized when a 3:7 volume ratio of 3‐methacryloxypropyltrimethoxysilane (MEMO): 3‐aminopropyltrimethoxysilane (A‐1110) was used to modify the stainless steel substrate. SEM images of EAA/LLDPE film peel surfaces found the silane‐treated stainless steel substrates produced rough surfaces with a uniform void indicating the silane treatment enhanced the stainless steel and EAA/LLDPE film interaction. The stainless steel and EAA/LLDPE film adhesion and water resistance improved and the peel strength after water resistance testing at 68°C for 168 h increased from 3.18 N/cm to 9.37 N/cm compared to untreated stainless steel. Silane‐modified stainless steel and EAA/LLDPE blend film composite materials demonstrate potential for application in wires and cables used in environmental corrosion‐resistant applications. POLYM.

Ni-free 23Cr-1N stainless steel was examined as bipolar plates for proton exchange membrane fuel cells. Corrosion resistance of the 23Cr-1N stainless steel was better relative to 22Cr stainless steel in the simulated cathodic environments. As confirmed by X-ray photoelectron spectroscopy, the polarized 22Cr and 23Cr-1N stainless steels at pH 2.3 presented predominantly chromium oxide in the outer passive layers. At pH 4.3, the passive layer of the polarized 22Cr stainless steel changed to iron oxides dominant. Interestingly, on the other hand, the polarized 23Cr-1N stainless steel preserved chromium oxide rich outer passive layer, which provides good corrosion resistance. As a result, although the initial cell voltage was slightly lower (∼40 mV), the 23Cr-1N stainless steel bipolar plates employing cell showed better cell voltage stability up to 1000 h, compared with the 22Cr stainless steel employing cell. The operation voltage became further higher through a surface modification of the 23Cr-1N stainless steel with TiN nanoparticles. It seems that the corrosion resistive Ni-free 23Cr-1N is possible to apply for bipolar plates of proton exchange membrane fuel cells. 相似文献
