Although the melt pool convection currents influence the dilution , porosity and distribution of potentially included hard phase particles such as carbide or other ceramic particles , which are added to increase the wear resistance of the deposited material , there is only limited knowledge of melt pool dynamics within blown powder additive manufacturing processes .
