Modification Process

A modification process on hematite nanoplates leads to controlled surface area ratio of (0001) facets and Ni-doped surfaces. Electrochemical testing shows the enhancement of water oxidation activity by Ni-doping increases as the surface area ratio of (0001) facets increases.

Topographic Parameters

Surface microtopography plays a dual role in the course of friction and wear processes. It affectsthe contact and temperature conditions, and it undergoes significant changes in accordance with the wearmechanism. Fractal dimension (Df), root mean square gradient (Sdq), surface area ratio (Sdr) and surfacekurtosis (Sku) parameters of microtopographies provides opportunities for understanding more deeply thewear processes independently from the amplitude of the roughness. Wear experiments and surfaceroughness measurements before and after wear were performed. Investigations extended to wear in thecourse of the non-lubricated ferrodo-steel material pairs, and lubricated camshaft-bushing pairs.
