Correlation between Wear Resistance and Lifetime of Electrical Contacts
Figure 23
(a) Line scans of gold in the contact area (white line). Due to the high wear resistance of gold plating, contact survives a more than 50,000-cycle test. Average depth of wear crater was 4 μm. (b) Line scans of gold in the contact area (white line). Due to the poor wear resistance, the gold plating is worn out after a 50,000-cycle test. Average depth of wear crater was 6 μm.
