Abstract


This works presents an overview of the tribological performance of various Ni and Co based electrodeposits under different contact conditions that relate to a field of applications. By applying meso-loads tests, the frictional and wear performance of thin nanostructured layers can be more realistically evaluated for micro-electronic systems (without overstressing the system and by minimizing substrate effect), whereas macro-loads can be used to simulate larger mechanical components. The key to this tribological approach is to simulate similar contact conditions and generate the same wear mechanisms as in the end-user application.
