AbstractThe facture behavior of a chromium (Cr) coating/ laser pre-quenched steel substrate system was investigated in this work. The results presented in this work show the crack density of the Cr coating on the laser pre-quenched steel substrate increases with the increase of the thermal fatigue times, and the failure process and modes of the Cr coating/laser pre-quenched steel substrate are the same as those presented in our previous work. However, the crack density of Cr coating on the pre-quenched substrate surface was much lower than that of the Cr coating on the original substrate surface under the same thermal fatigue loading. This indicates the Cr coating on the pre-quenched steel substrate has superior mechanical properties than that on the original steel substrate. © (2014) Trans Tech Publications, Switzerland.
