| Popis: | For most applications, martensitic stainless steels are subject to operating conditions where good mechanical properties and wear resistance are required. Soldering soft martensitic stainless steels features decreased tenacity of the welded joint which, along with the residual stresses, can shorten the life of component and accelerate the cavitation process. In order to increase the strength of the martensitic structures, thermal spraying is used to produce coatings, laid without resulting in thermal cycles that influence the structural integrity of the coated steels. This work was deposited by the electric arc and wire flame, the 410NiMo martensitic stainless steel, in wire and rod form, respectively, on the substrate of the martensitic stainless steel CA6NM. The samples were sent to Vickers microhardness tests and accelerated cavitation, according to ASTM G32-10. The results were obtained through optical microscopy, X-ray diffraction, SEM, and dispersive energy spectroscopy (DES); the samples featured high adhesion, low porosity, and cavitation erosion–resistant coatings. The thermal spray is suitable for the application of this type of coating. |
