Plasma transferred arc additive manufacturing of Nickel metal matrix composites. Manufacturing Letters, 18, 31-34.2213-8463https://doi.org/10.1016/j.mfglet.2018.10.001https://hdl.handle.net/11285/637237This paper analyzes the geometric stability and microstructure characteristics of metal additive manufacturing parts using plasma transferred arc with Metal Matrix Composites. The technology used to enhance the capabilities of a plasma system to create an additive manufacturing system is described. Geometric stability, microstructure porosity and cross-sectional hardness analysis of the additive manufacturing parts are discussed. This work confirms that the new capabilities of the system allow building a 3D printed part of nickel-base metal matrix with tungsten carbide particles for wear resistance. The results will lead to the development of large-scale additive manufacturing parts for industrial purposes.TextoengrestrictedAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0INGENIERÍA Y TECNOLOGÍA::CIENCIAS TECNOLÓGICAS::TECNOLOGÍA E INGENIERÍA MECÁNICAS::DISEÑO DE MÁQUINASTechnologyArtículoManufacturing Lettershttps://orcid.org/0000-0003-4198-9970Plasma transferred arcMetal matrix compositeAdditive manufacturingGeometric stabilityMicrostructureTungsten carbide1820183134Estados Unidos de América / United States327999Mercado Rojas J.G.
