Friction Coefficient of Potassium and Sodium Dichromate Doped Epoxy

Abstract

In this article, we describe a less conventional method of ultrasound exposure and friction coefficient variation regarding the formation of composites with two different salts of doped epoxy resin at three concentrations. Although the method is easily applied, we have illustrated that the doping method has a good influence on friction coefficient variation for three applied regimes. Introduced into a nitro solvent and then on an epoxy resin, the potassium and sodium dichromate dispersion homogeneity influence extensively the composite's performance. As ultra-sonication is a very used method to disperse the particles into the polymer matrix, this study is motivated by the desire to identify the ways in which is possible to obtain a composite with a good friction coefficient.
