Device having low-friction surfaces, and method to reduce the friction coefficient.

摘要

Method for lowering the friction coefficient between a first and a second device moving in a relative sliding motion with respect to each other, and in particular made from base materials consisting of elastomers or plastics, and from glass, respectively, which method is of the type consisting in producing, at least at the surface, at least the portion or portions of the said first device which comes or come into contact with the said second device from a polymer having a low friction coefficient. The method is characterised in that the sliding surface or surfaces of the said first device is or are obtained by incorporating into the compound of this first device an appropriate proportion of the said polymer with a low friction coefficient, and by the successive migration of this polymer towards the outer surface of the first device. Application to the automotive and building industries.
