The aim of this paper was to address the accelerated fatigue life under rolling contact condition of thermal sprayed coatings.The NiCr-Cr_3C_2 ceramic-metal were deposited on 1045 steel substrates using supersonic plasma spraying technique. Accelerated fatigue life tests were conducted using the ball-on-disc tester.The life of NiCr-Cr_3C_2 coatings were evaluated by WeibulI distribution plots.At the samc time,the accelerated fatigue life model was obtained.SEM was employed to observe the morphologies of coa...
