Abstract
This 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.
