Thermochemical surface hardening of Ti-6Al-4V: On the role of temperature and treatment media
Abstract
<p>The present work addresses the surfacehardening and heat treatment response of Ti-6Al-4V grades G5 and G23 onthermochemical surface treatment in different temperature regimes aswell as in different gaseous and plasma-based media. Grades G5 and G23were subjected to gaseous surface hardening using various gascompositions and temperature regimes. Two different series of gaseoussurface treatments were carried out:</p><p>1)carbo-oxidizing of G23 in mill-annealed condition was performed in COgas at (high) temperatures ranging from 777 to 1027 °C. Treatment at1027 °C resulted in the deepest case with the formation of a thinsurface layer of titanium sub-oxides supported by a thick TiC<sub>x</sub>O<sub>1-x</sub> layer as the dominant phase. Post-nitriding of the carbo-oxidized specimen raised the hardness of the TiC<sub>x</sub>O<sub>1-x</sub> phase by the incorporation of nitrogen, yielding values up to ~2,900 HV and multi-layered structures.</p><p>2) Carbo-oxidizing of G5 with a bi-modal microstructure in CO/CO<sub>2</sub>gas mixture at (intermediate) temperatures in the range 677 - 777 °C.Treatment at 777 °C resulted in a surface hardness of ~1,900 HV and a~60 μm-thick diffusion zone.</p><p>In addition to gaseoussurface hardening, also plasma-assisted methods were applied andcompared to their gaseous counterparts. Intermediate- andlow-temperature plasma treatments were carried out on G23:</p><p>3) plasma (carbo-nitro)oxidizing was performed in a CO<sub>2</sub> and N<sub>2</sub> gas mixture at 750 °C and (carbo-)oxidizing in CO<sub>2</sub> gas at 650 °C.</p><p>4) Plasma nitriding was conducted in a N<sub>2</sub>/H<sub>2</sub>gas mixture at 750 °C and 850 °C. The widely different types oftreatments applied in this work represent the diversity of the gaseousand plasma-based thermochemical methods that can be applied for surfaceengineering of titanium alloys.</p>
