Purpose: The aim of this work is to present the main initial results on the development of the niobium plasma carburizing process. Design/methodology/approach: The development of a new pulsed direct current power supply plasma assisted thermo-chemical treatment process for niobium. Findings: Niobium plasma carburizing can be successfully carried out, and niobium carbide phases can be obtained in the treated surface. Research limitations/implications: The risk of arc formation during the surface treatment can be overcome by optimizing the discharge geometry. Practical implications: The highly reactive plasma atmosphere is an advantage regarding the other conventional treatment processes. Originality/value: It is a new process development, and in this moment it is being considered to be patented in Brazil by the authors.
