Certain aspects of friction between natural polymers and metal

  • B. I. Kupchinov


It is shown, on the basis of test data, that one of the most likely processes responsible for the adhesive characteristics of a friction contact between metal and wood is the formation of compounds containing the metal, namely, compounds between metal oxides and active groups within the lignocarbon complex in wood (hydroxyl groups, for example) with an electropositive hydrogen atom. The correlation established here between the molecular component of the friction coefficient, the change in OH groups, and the moisture absorption level in wood yields criteria for selecting the filler materials which will ensure, during friction, that the positive gradients of resistance to shear become localized and that stable boundary layers form within the contact zone.
