In these experiments, we heated the sample-holder with a shielded resistive wire properly wound around it and subjected the SS samples to nitrogen glow discharge PIII with relatively low voltages (10 kV) in different temperatures. We also treated the SS samples by the traditional PIII method, slowly increasing the high voltage pulse intensities, until 14 kV at the end of processing, reaching temperatures of up to 350 °C. These modes of treatments were compared with respect to nitrogen implantation profiles, X-ray diffraction, tribology and mechanical properties. X-ray diffraction results indicated a much higher efficiency of auxiliary heated PIII mode compared to the ordinary PIII. Very prominent ãN peaks were observed for the first mode, indicating large concentration of nitrogen in thick layers, confirmed by the nitrogen profiles measured by GDOS and AES. Improved mechanical and tribological properties were obtained for SS304 samples treated by the PIII with auxiliary heating, more than for ordinary PIII. Hardness was enhanced by up to 2.77 times, as seen by nanoindentation tests. %@mirrorrepository sid.inpe.br/mtc-m19@80/2009/08.21.17.02.53 %8 Dec. %N 5 %T Tribological changes on SS304 stainless steel induced by nitrogen plasma immersion ion implantation with and without auxiliary heating %@secondarytype PRE PI %K Plasma immersion ion implantation, SS304, Tribology. %@group LAP-CTE-INPE-MCT-BR %@group LAP-CTE-INPE-MCT-BR %@secondarykey INPE--PRE/ %@secondarymark B2_ASTRONOMIA_/_FÍSICA B2_CIÊNCIAS_BIOLÓGICAS_I B2_CIÊNCIAS_BIOLÓGICAS_II B1_ECOLOGIA_E_MEIO_AMBIENTE B1_ENGENHARIAS_II A2_ENGENHARIAS_III B1_ENGENHARIAS_IV A2_INTERDISCIPLINAR B2_MATEMÁTICA_/_PROBABILIDADE_E_ESTATÍSTICA B1_MATERIAIS B1_MEDICINA_III B1_ODONTOLOGIA B3_QUÍMICA %@issn 0169-4332 %2 sid.inpe.br/mtc-m19@80/2009/12.10.15.38.09 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Universidade Federal do Paraná %@affiliation Institute of Ion Beam Physics and Materials Research %B Applied Surface Science %P 1461-1465 %4 sid.inpe.br/mtc-m19@80/2009/12.10.15.38 %D 2009 %V 256 %@doi 10.1016/j.apsusc.2009.09.001 %A Mello, Carina Barros, %A Ueda, Mário, %A Lepienski, C.
