Effect Gamma rays effect on Wear rate and Hardness of ( Ep-SiC ) Nanocomposites for Industrial applications

Abstract

The aim of this research is to measure the hardness and wear rate for epoxy resin as a base material, nano ceramic powder (SiC) with particle size ( 64.85nm ) , were used as a reinforcement materials in composites preparation in different weight fractures (2%, 4%, 6%), hand-casting method was used in preparation the research samples, Mechanical properties were measured after irradiation of gamma rays emitted from the CO60 with energy rate of 1.33MeV and different irradiation doses (6,8,10) KGy. The results showed an increase in the hardness values after the irradiation compared with the results before irradiation while wear test showed a decrease in the values in normal conditions compare with the result after irradiation.
