Adhesion force measurements between deep-sea soil particles and metals by in situ AFM
AbstractDeep-sea soil particles collected from the Pacific C-C area were successfully immobilized on commercial AFM cantilever by a home-made test apparatus. Using this modified probe, adhesion force distribution between the deep-sea soil particle and four metals was measured by in situ AFM. The factors influencing the adhesion force were investigated. The adhesion forces between soil particles and the metal surface were ranked in an order of aluminum alloy (5052)<titanium alloy (STi80)<pure titanium (TA2)<titanium alloy (TC4) under same roughness, indicating the self-cleaning property of 5052 is better than the others. Furthermore, the results suggest the adhesion force decreases as the roughness increases within a certain range. The adhesion forces were determined by the surface energy and the contact radius based on JKR contact model.
HighlightsWe assembled a apparatus to modify the tipless probe.The adhesive interaction between deep-sea soil particle and metals was measured by in situ AFM technology.We found the two key factors influencing adhesion force are the surface energy and the contact radius determined by asperity.
