Computer Methods and Experimental Measurements for Surface Effects and Contact Mechanics VIII 

The combination of surface treatment and contact mechanics is an important one. The surface of a component is usually the most important engineering factor. While it is in use it is often the surface of a work-piece that is subjected to wear and corrosion. The complexity of the tribological properties of materials and the economic aspects of fricti
