摘要
为了揭示软熔导电辊失效机理,首先对失效软熔导电辊表面进行形貌观察,接着分析了其表面的黏附物的成分,最后跟踪分析了软熔导电辊表面粗糙度的下降过程。结果表明:粘锡是软熔导电辊失效的主要原因,磨损也加剧了软熔导电辊的失效,并首次给出了软熔导电辊使用中磨损和粘锡分量。最后提出了减轻和控制软熔导电辊粘锡以及提高软熔导电辊耐磨性的对策。
To disclose the failure mechanism of reflow conducting roll （RCR）, its surface morohology was observed, the composition of the adhered materials on RCR surface was analyzed, and the surface roughness decreasing process of RCR was tracked and analyzed. Results show that adhered tin is the main reason for the RCR failure, and wear quickens it. The wear and adhered tin masses were given out for the first time, and finally the measures decreasing the adhered tin and improving the wear resistance of RCR were put forward.
