摘要：

On the surface of a 17-4 PH stainless steel, powders from the cermet group were submitted, using the plasma thermal spray technique on a METCO SULZER installation. Thereafter, a part of the sprayed samples were remelted at the surface withu the Nd:YAG laser beam, on a Trumpf HL 123 LCU installation. The cavitation behavior of the samples was tested using an ultrasonic vibratory cavitation erosion equipment. The examination at the optical microscope and scanning electronic microscope of the marginal layer and of the cavitated surface revealed the formation of a dense microstructure, finished by remelting, which explains the increase by 133 % of the erosion resistance compared with the structural state obtained through 1050 C solution treatment with air cooling.
