Tin coatings are widely used in automotive connectors for applications where temperature are not too severe. Currently, there is no consensus concerning the limit temperature to use tin coatings. The aim of this study is to study the thermal ageing of the copper/tin systems in the connector field, and to estimate the lifetime performance, i.e. under a medium current (producing Joule effect), and in a vibratory state (fretting-corrosion). The copper/tin interdiffusion leads to the formation of intermetallic phases (Cu6Sn5 et Cu3Sn). The growth kinetics of intermetallics is studied as a function of the nature of the coating, of the use of a nickel underlayer or not, (leading to the formation of a Ni3Sn4 intermetallic phase), and of the nature...
