Abstract

In this study, for EPDM rubber conventionally used as a radiator hose material the aging behaviors of the skin part under the electro-chemical stresses were nondestructively evaluated. On account of the penetration of coolant liquid into the skin part the weight of rubber specimens degraded by ECD test increased, whereas their failure strain and IRHD hardness decreased largely. The penetration of coolant liquid seemed to induce some changes in inner structure and micro hardness distribution of the rubbers. Consequently, EPDM rubbers degraded by ECD could be characterized nondestructively by micro-hardness and chemical structure analysis methods.
