Finite element modeling of solid particle erosion in AISI 4140 steel and nickel-tungsten carbide composite material produced by the laser-based powder deposition process

► A FE dynamic model was used to study the slurry erosion in Ni-WC composite material. ► The model is verified by experiments that considers both Ni and WC separately. ► A correlation between erosion resistance and the volume fraction of WC in Ni was found. ► A soft interlayer provided more resistant to erosion in a multilayered Ni-WC deposit.
