Abstract
Measurements have been made of the coefficients of friction for graphite and some graphite‐based materials which are of interest for nuclear reactor application. Static and kinetic friction coefficients have been measured as a function of surface conditioning and temperature up to a maximum temperature of 2450°C. In addition, the effects of force, stress, anisotropy, refractory coating, and uranium loading were studied. The most significant effect was found to be caused by the conditioning of the contact surfaces by polishing action, and this was more pronounced in the static than the kinetic friction coefficient. The friction coefficients increase with temperature. Other effects studied had negligible influence.This publication has 5 references indexed in Scilit:
