Contact fatigue behavior of α-Al2O3-Ti(C,N) CVD coated WC-Co under dry and wet conditions

•Response to cycling contact fatigue of Ti(C,N)/α-Al2O3 CVD coated carbide.•Experimental set-up allows for wet and dry cycling contact tests.•Imprints in dry tests characterized by cracks forming a circumference at maximum radii.•Wet indentations imprints present a ring where the α-Al2O3 layer is re...
