N2  - In this paper the Greenwood and Williamson contact theory for microscopically
rough surfaces is generalized by considering a grading on the elastic modulus of the asperities.
This situation can be representative of surfaces receiving superficial treatments or characterized by
a chemical degradation. The effect of an exponential grading on the applied normal load, on the
relationship between the real contact area and the load, on the plasticity index, as well as on the
contact conductance is illustrated with detailed numerical examples.
