  text: The reliability and lifetime of electrical contacts is an important aspect
    in system reliability and is influenced by numerous factors. Micro motions as
    well as vibrations lead to fretting wear, which can result in wear through of
    the protective coating. If this layer is worn through, the non-noble layer underneath
    is exposed, resulting in the occurrence of fretting corrosion with further relative
    motion. This leads to an increased electrical contact resistance (ECR) and can
    cause the contact to fail. Increasing the hardness of the coating material can
    reduce the wear and in turn increase contacts’ lifetime. The micro hardness, wear
    and lifetime of contacts with modified hard silver coatings are investigated in
    fretting wear and corrosion tests and the results compared to a conventional silver
    coating. Since one of the modifications shows a significant reduction in wear
    and hence improvement in lifetime, further analysis with SEM and FIB is conducted
    in order to identify the key mechanisms leading to this improvement. With a further
    increase in lifetime however, fatigue as well as delamination of the coating are
    revealed to be of high relevance. Both can be main causes of electrical contact
    failure under fretting load. In general, at lower number of cycles, increased
    micro hardness has the greatest effect on lifetime and wear while at the higher
    number of cycles, fatigue is observed to be the dominant failure mechanism.
