Zinc and iron particles are present in a lubricating oil. Which will have higher tendency to form oxide?
zinc has higher tendency to form oxide, Look at Ellingham diagram.
I had a mineral oil of 460cSt (containing sulphur and phosphorus), after addition of nanparticles (carbon nano tubes and graphene) the viscosity decreased significantly. literatures says that the...
