Abstract: For tribological properties, the mechanical response to contact is particularly important if performance is to be understood. These model predictions have been tested experimentally using flat cylindrical indenter. During the loading steps of the indentation of elastoplastic materials, the total penetration depth (or deformation of pin) is the summation of the elastic and plastic depths. The plastic depth corresponds to the contact depth, which is used to determine the contact area, load-holding creep grow of plastics are different from metals, so deformations can significantly influent the estimated wear data. Due the dry wear tests with poliamide and poliacetalhomopolimer plastics wear value can be fogged by deformation level of sample. This paper describes an experimental study of contact compliance data for deriving polymer tribological properties
