摘要

研究了镀银的晶间粘聚对润滑滑动车灯开关断续工作的影响。微动类型的测试被用来跟踪开关的间歇性行为的演变。结果表明，镀银工艺的变化对镀银触点的质量和表面形貌有明显的影响。发现这种间断现象是由于镀银的晶间凝聚力降低导致表面拓扑结构发生变化而引起的开关断裂现象。随后的抛光消除了间歇性，并且在开关寿命的后期不存在。讨论了对观察到的间歇效应的合理解释。微动型试验被证明是一种非常有用的技术，可以获得简单的硬度测量无法提供的镀层质量信息。

Effect of intergranular cohesion on the intermittency of automotive headlamp switch contacts

The effect of intergranular cohesion of silver-plating on the intermittent operation of a lubricated sliding automotive headlamp switch was investigated. Fretting types of testing were used to follow the evolution of the intermittent behavior of the switch. It was found that processing variations of the silver electroplate exerted pronounced effect on the quality and surface topography of silver-plated contacts. The intermittency was found to be a switch break-in phenomenon caused by the changes in surface topology resulting from a reduced intergranular cohesion of silver-plating. Subsequent burnishing eliminated the intermittency and it was not present later in the switch life. Plausible explanations to account for the observed intermittent effect were discussed. Fretting type testing proved to be a very useful technique in obtaining information on the plating quality that simple hardness measurements could not provide.
