Corrosion is a naturally occurring process, which converts refined metals into a more chemically stable form. This could be an oxide, hydroxide, or sulfide. Corrosion is the gradual destruction of metals by chemical or electrochemical […]

Adhesive Wear Particles Generation: by Fracture or Atom-by-Atom?

01.08.2016 579 Views

The most famous equation to predict wear known probably to everyone working in the field of tribology is Archard’s model (1953). The model assumes that wear occurs through the fracture of plastically deformed material and [...]
