—The complex structure of Ta 2 O 5 led to the development of various structural models. Among them, superstructures represent the most stable configurations. However, their formation requires kinetic activity and long-range ordering processes, which are hardly present during physical vapor deposition. Based on nano-beam X-ray diffraction and concomitant ab(More)
a r t i c l e i n f o Based on previous reports, showing that zirconium alloying to Ti 1 − x Al x N hard coatings can increase their thermal stability, we study in detail the interaction of bias potential and Al content on structure, hardness, thermal stability, and oxidation resistance of arc evaporated Ti 1 − x − y Al x Zr y N hard coatings. For moderate(More)
Transition metal nitrides like CrN and TiN are widely used in automotive applications due to their high hardness and wear resistance. Recently, we showed that a multilayer architecture of CrN and TiN, deposited using the hybrid—high power impulse magnetron sputtering (HIP-IMS) and direct current magnetron sputtering (DCMS)— HIPIMS/DCMS deposition technique,(More)
a r t i c l e i n f o Alloying Ti–Al–N coatings with Ta has proven to enhance their hardness, thermal stability, and oxidation resistance. However, especially for arc-evaporated Ti–Al–Ta–N coatings only limited information on the detailed influence of the elements on various properties is available. Therefore, we have developed arc-evaporated Ti 1−x−y Al x(More)
