...Yu-Tse Lin, MSc; Wen-Chung Liu, PhD; Chin-Chiuan Kuo, PhD Titanium–zirconium nitride films with three Zr/Ti ratios (16/35, 22/29, and 25/26) were deposited using Ti and Zr dual-cathode reactive high-power impulse closed-field magnetron sputtering by adjusting the average power ratio of two cathode...

...Naim Syla, Dr Sc; Fisnik Aliaj, Dr Sc; Bashkim Dalipi, Dr Sc; Njomza Elezaj, MSc; Arbër Zeqiraj, MSc This research aims to determine the depth of diffusion of nitrogen in steel 16MnCr5 after gas nitriding. Nitriding was performed in the ammonia atmosphere at three temperatures (510, 550 and 590°C...

...Naim Syla, DSc; Bashkim Dalipi, DSc; Njomza Elezaj, MSc; Fisnik Aliaj, DSc; Zeqë Tolaj, MSc; Arbër Zeqiraj, MSc This paper presents a possibility for the numerical calculation of the profile of nitrogen (N) concentration in 31CrMoV9 steel after gas nitriding. Samples subjected to gas nitriding...

...Naim Syla, Dr.Sc; Arbër Zeqiraj, MSc; Nazmi Hasi, Dr.Sc.; Njomza Elezaj, MSc The aim of this research is the investigation of the compound layer formed by steel 16MnCr5 after gas nitriding. The investigation was carried out with metallographic methods – that is, with optical microscopy and electron...
