Abstract
⺠We investigated the fatigue behavior of a 4340 steel coated with a WC-10Co-4Cr/Colmonoy 88 deposit. ⺠The coating was deposited by HVOF thermal spray after prior grit blasting and it is very heterogeneous. ⺠The mechanical properties of the coating were characterized by means of nanoindentation tests. ⺠The coating deposited gives rise to a significant decrease in the fatigue strength of the substrate. ⺠The decrease in fatigue strength is due to the presence of stress concentrators at the substrate-coating interface.
