“…Coatings can be formed if the melted fused projectile can deform at the shocks with the substrate. Wire Arc Spray Process (WASP)is one of several technics which consist on being two wires consumable arc electrodes, are drawn from spools and form a liquid droplet due to arc heating [6][7][8][9][10]. The droplet is blown by the atomizing gas.…”

Thermally sprayed of X30Cr13 martensitic stainless steel coatings are widely used to reduce degradation of components and structures due to mechanical wear. In this paper, the microstructure and mechanical properties of X30Cr13 coated onto on 35CrMo4 using Wire Arc Spray Process (WASP) are investigated. These coatings were made with to different system bond-coat layer which is constituted by Ni-Al. The microstructure characteristics of the coatings are studied using the combined techniques of X-ray diffraction (XRD), scanning electron microscopy (SEM). Measurements of Vickers hardness was carried out on top of the surface of stainless steel. The scanning electron microscopy presents a dense microstructure of this stainless steel, which had a homogeneous compact lamellae shape with the presence of pores and unmelted particles. The wear resistance of the two systems composite Sub/Bond-Coat/X30Cr13 and Sub/X30Cr13 is affected by sliding velocities under different applied loads. The system composite Sub/X30Cr13exhibits low wear resistance than Sub/Bond-Coat/X30Cr13 coating.
