Title: Friction properties of nanometer metal coatings prepared by ion beam enhanced deposition

Influences of load and sliding velocity on friction properties were analyzed. The differences among four coatings were discussed. The results indicate that the friction force of copper keeps invariable and the friction forces of nickel coating and titanium coating increase slightly and markedly respectively with increasing sliding velocity. However, with increasing sliding velocity, the friction force of aluminium coating decreases. The friction forces of all four kinds of coatings increase with increasing load. There exists a threshold, which friction forces increase sharply when load exceeds it. The phenomena can be explained by the concept of contact stiffness. The friction force of copper coating is the least and the friction force of aluminium is the largest. The differences among these four coatings can be explained by structure and topography of coatings.Read More
