Abstract

Ni60 coating and Ni60/WC coating were prepared on the surface of H13 steel by PTAW, and some Ni60/WC coatings were annealed. The effect of annealing temperature on the microstructure of Ni60/WC coating was studied. The thermal fatigue test of the coating samples were carried out by a homemade thermal fatigue testing apparatus. The thermal fatigue properties of Ni60 and Ni60/WC coatings were compared. Mainly investigated the performance of Ni60/WC coatings annealed at different temperatures. The results show that the addition of WC reduces the thermal fatigue properties of the Ni60/WC coating. The annealing treatment weakens the crack sensitivity of the Ni60/WC coating and the WC distribution is improved, which is better at 800 °C annealing.
