Abstract

The  wetting  transition  is  studied  for  the  oil  droplets  placed  on  the  underwater  surface  of  metal  matrix composites. Oil penetration into the cavities between the asperities is accompanied by a change in the contact angle and may result in the Cassie-Wenzel transitions. Experimental data of contact angles of oil-air, water-air, and  oil-water  systems  on  the  surface of  aluminum-graphite  composites  are  collected. The  Wenzel-Cassie wetting transition is revealed by increasing the roughness for various aluminum-graphite samples. A theoretical model is proposed to verify the effect of surface topography and roughness on the wetting transitions.
