| Abstract: | The early stage of the wear process can be best investigated by means of three-dimensional profilometry. This allows not only maps to be made but also wear rates to be quantified. Linear, surface and volumetric parameters are given.An application to the wear resistance of amorphous NiB coatings (thickness, 10 μm; 26 at.% B) on iron substrates was performed. Dry sliding friction tests are carried out using a pin-on-disc system. Two specific types of behaviour (viscoplastic and plastic) are exhibited before seizure occurs. |
