Abstract

Selective laser melting implementation by gas turbine engine combustor chambers manufacturing difficult machining material Ni-Co-Cr alloy is an actual task to directly form complicated shapes. The paper shows the study of Ni-Co-Cr powder such as chemical, morphology, grain size, flow rate, and pour density analysis. The study results demonstrate the structure of Ni-Co-Cr alloy manufactured by selective laser melting in vertical and horizontal directions in original condition and after hot isostatic pressing. It is established that hot isostatic pressing offers the possibility to reduce the porosity and improve the mechanical properties. The influence of the hot isostatic pressing process on the density and microstructure of Ni-Co-Cr alloy is investigated by means of X-ray phase analysis and scanning electron microscopy. The results of the experiments show that the majority of the pore can be densified by means of hot isostatic pressing. The study presents the SLM technology implementation by producing the small size gas turbine engine combustor chamber.
