Questions and Answers

What is the assumption regarding contact between two surfaces in terms of asperities?

  • The contact is limited to half of the individual asperity contact areas.
  • The contact area is inversely proportional to the normal load.
  • The contact occurs where asperities touch, and the true area of contact is equal to the sum of individual asperity contact areas. (correct)
  • The contact occurs only when the surfaces are perfectly smooth.

Which factor plays a major role in a material's resistance to corrosive wear?

  • Surface roughness
  • Applied load
  • Material properties (correct)
  • Temperature

What type of deformation is expected for the asperities during contact?

  • No deformation
  • Plastic deformation (correct)
  • Elastic deformation
  • Permanent deformation
