| The transportation of shale gas has the problem that the piping used for the extraction does not resist the erosion generated by the amount of solids causingcracksoverthesurfaceandit is necessaryto extendthe lifeofthepipelines. Plasma transferred arc (PTA) welded coatings are used to improve the surface properties of mechanical parts. Therefore, in this paper is studied the use of Nibased filler metal as weld bead deposits on A36 steel substrates by PTA. In order to determinethe suitable conditionsto ensurecoatingquality onthe substrate a design of experiments(DOE) was determined.Welding current,feed rate, and travel speed were used as input parameters and the dilution percentage as the response variable. The composition and properties of hardfacing or overlay deposited are strongly influencedbythedilutionobtained.Controlofdilutionisimportant,wheretypically low dilution is desirable. When the dilution is low, the final deposit composition will be closer to that of the filler metal, and the wear and corrosion resistance of the hardfacing will also be maintained. To evaluate the features on the weld beads/substrateinterfacea microstructuralcharacterizationwas performedby using scanningelectronmicroscopyandtoevaluatethe mechanicalpropertieswas carried out hardness test. | |
