abstract = "High temperature nitrogen plasma immersion ion implantation
(HT-NPIII) method was used to treat the internal walls of small
diameter metal tubes made of SS304 and of Ti6-Al4-V (TAV). Using a
lid in one side of the tubes was essential to reach high
temperatures of 700900 °C, necessary for high thermal diffusion of
nitrogen in Ti alloy samples placed inside the metal tubes for
monitoring the HT-NPIII process. The used metal tubes also reached
such high temperatures. New phases of TiN and Ti2N were
successfully attained in the TAV samples with the treated layer
thickness of more than 1.3 \μm for all the tested cases. For
tubes made of SS304, HT-NPIII treatments resulted in redeposition
of FeN thick layers with high hardness on the surfaces of the
internal walls of the tubes and on the monitoring samples.
Obtaining such HT-NPIII conditions in these small metallic tubes
was possible by achieving high plasma density through hollow
cathode discharges inside those tubes. These results were compared
to the ones obtained on the nitrogen implantation treatments of
TAV samples in moderate to high temperatures carried out
previously in the laboratory which indicated the superior
performance of the presently reported method of surface
modification.",
