摘要
Two types of commercial WC-Ni samples were irradiated with the High-intensity pulsed ion beam(HIPIB).Both the surface characteristics and tribo-characteristics of the non-irradiated and irradiated WC-Ni samples,sliding against graphite under water lubrication,were compared.Quite low steady friction coefficients(approximately of 0.02) of the irradiated WC-Ni were observed.The surface topographies and components were investigated.The quite low friction of the irradiated WC-Ni samples was ascribed to the higher fluid retention capability of the latter and the tribofilm formed during sliding.
