Properties of Ti/TiN composite layers produced by "in situ" method with the use of high power diode laser

Aleksander Lisiecki, Damian Janicki, Andrzej Grabowski, Klaudiusz Gołombek

It has been described the results of testing of the structure and properties of surface Ti/TiN composite layers produced „in situ” in consequence of remelting of the surface layer of the Ti6Al4V titanium alloy plate by means of high power diode laser under pure nitrogen (laser gas nitriding). The influence of the parameters of the laser gas nitriding process on the microstructure of surface layers, microhardness, abrasive wear resistance of the metal-metal type and erosive wear resistance at different glancing angles of the erodent has been analyzed.
