Abstract
In this paper, high current pulsed electron beam (HCPEB) was used for the irradiation of TiN coating. The impact of the modification conditions, including the energy density of electron beam and pulse number, on the morphology, phase composition, surface roughness and mechanical behavior of the TiN coatings were investigated with scanning electron microscope, atomic force microscope, X-ray diffraction, and conventional mechanical probes. The results showed that the HCPEB irradiation melted the TiN coatings and strongly increased the surface roughness due to the irradiation-induced surface damage; the XRD diffraction peak intensity of the irradiated TiN coating was changed. Moreover, for the HCPEB irradiation of energy density 5 J/cm2 and 20 pulses, the interfacial adhesion of the treated TiN coating was increased obviously.
