摘要

A model for constriction resistance between two rough, coated surfaces has been developed. A coated semi-infinite cylinder terminating in the frustum of a cone is analyzed. The effect of five different geometrical and material property parameters has been explored, and a generalized correlation equation has been developed. In ongoing work, the results of this modeling effort are being integrated with a surface deformation analysis to generate a predictive model for the thermal contact resistance at the interface between two metallic, coated surfaces. Experiments are also underway that will generate a comprehensive database of contact resistance values for coated surfaces and will be used to validate the predictive model.
