Fretting tests with an AuCo/Ni vs. Au/NiP ball to plate contact were conducted in order to describe the ongoing wear mechanisms. Furthermore, a global wear approach was chosen to quantify the overall wear. According to a predefined electrical failure criterion the connector lifetime is demonstrated in a model depending on oscillating amplitude, gold thickness and contact roughness. The electrical failure of the contact can be reduced to the wear of the gold platings leading to exposure of the nickel interlayer and consequently oxidation. Through material transfer, plowing, particle generation and the particle transport mechanisms the contact resistance increases and therefore limits the connector lifetime. The link between the lifetime models and the global wear approach allows for calculation of the lifetime when only the wear and the stress of the tribosystem are known. 606 $aTechnology: general issues$2bicssc 610 $aelectrical contacts 610 $aelektrischer Steckkontakte 610 $afretting 610 $agold 610 $aGold 610 $aSchwingverschleiß 610 $aTribologie 610 $atribology 615 7$aTechnology: general issues 700 $aHoppe$b Tobias$4auth$01304692 906 $aBOOK 912 $a9910347056603321 996 $aDie tribologischen Eigenschaften von vergoldeten elektrischen Kontakten$93027612 997 $aUNINA
