초록

Intense electron beam was irradiated on the CrAlN thin films deposited in SKD61 under different incident energies and then the effect of electron beam irradiation on the enhancement of surface hardness and wear resistance was investigated. Surface hardness and wear resistance of the CrAlN films is increased proportionally with the electron beam energy. While the surface hardness of as deposited CrAlN film is Hv ($0.1g{\cdot}f$) 450, the hardness oflectron irradiated (600 eV) film is Hv ($0.1g{\cdot}f$) 2050. The width of wear track of the untreated SKD61 is $X\_{\mu}m$, while the track-width of the electron irradiated CrAlN (600 eV) film is $787{\mu}m$, respectively. From the observed results, it is supposed that the optimal electron beam irradiation can be one of the useful surface treatment technologies for the enhancement of surface hardness and wear resistance of CrAlN/SKD61, simultaneously.
