Cutting tools are subjected to the intense wear solicitations. Usually, they either are subject to superficial heat treatments or are covered with various materials with high mechanical properties. In recent years, thermal spraying is used increasingly in engineering area because of the large range of materials that can be used for the coatings. Titanium nitride is a ceramic material with high hardness which is used to cover the cutting tools (drills, mills), increasing their lifetime. The paper presents the results obtained after deposition of titanium nitride layers by reactive plasma spraying (RPS). As deposition material was used titanium powder and as substratum was used titanium alloy (Ti6Al4V). Following the demonstration program have been achieved layers deposited with a thickness between 68,5 and 81,4 μm. Also, are presented the macroscopic and microscopic (scanning electron microscopy) images of the deposited layers.
