Abstract

Indentations and scratch tests using a Nano Indenter ®XP have been carried out to characterize the mar and wear resistance properties of polymeric bilayer systems. These systems were composed of a transparent coating on a thermoplastic polymer (PMMA) substrate. The different thin films were deposited using several coating technologies. Nanoindentation tests with a Berkovich indenter were performed at different peak loads from 0.625 to 10 mN, to determine the mechanical properties both of thin films and of the PMMA substrate, such as the elastic modulus and the hardness. A new analysis of the loading curve was applied to extract the viscoplasticity index. Then, scratch tests using a conical indenter truncated with a spherical tip (radius R = 5 μm) were realized with increasing progressively applied load (from 0 to 40 mN) to create irreversible damages (crack or delamination). The distinction between ductile and brittle behaviour in a scratch process leads to the definition of some specific parameters. For all tested specimens, we estimated the average contact pressure, the strain rate and the average strain beneath the indenter at which the fracture occurs. We propose a complete method to estimate with accuracy these differents parameters, from data supplied experimentally by the depth sensing instrument. This method takes into account the piling-up phenomenon and the viscoelastic recovery of the polymeric surface at the rear of the contact. No direct relationship was found between the viscoplasticity index and the ductile/brittle transition determined by the scratch test. Different criterions related to mar and scratch resistance were tested and compared to results obtained with macroscopic tests.
