AbstractAbstract
[en] The dynamic and static friction behavior of chromium carbide coatings containing Nichrome, Inconel 718, or Tribaloy 700 as binder materials has been investigated in sodium environments at temperatures ranging from 232 to 6270C (450 to 11600F). In general, dynamic friction coefficients of these materials at 2320C were found to be less than or equal to 0.4, but increased with temperature and cumulative rubbing, with values as high as 0.9 observed at 6270C following extensive rubbing. The detonation gun applied chromium carbide/Nichrome coated 316 stainless steel, exhibited a definite self-bonding tendency in high purity sodium, but little wear was observed. Static or breakaway friction coefficients were influenced by temperature, dwell time, contact pressure, and the presence of tangential forces at the contacting interfaces. Friction coefficients at 6270C were significantly lower for irradiated material than for similar unirradiated coatings
