“…1(c)) indicates that the coating consists of TiN and CrN [3][4][5]. Concerning Ti-Cr-N related phases which may be present in the TiCrN coatings, JCPDS files list Ti, Cr, CrN, Cr 2 N, TiN, and Ti 2 N. No Ternary Ti-Cr-N phases are listed, but Vetter et al [9] explained that the as-deposited TiCrN coatings consist of cubic (TiCr)N and hexagonal β-(CrTi) 2 N. The existence of these ternary phases needs further investigation. Fig.…”

Cyclic oxidation behavior of TiCrN coating deposited on a steel substrate by the Arc-ion plating method

The cyclic oxidation behavior of a TiCrN coating deposited on a steel substrate was studied at 700, 800, 900 and 1000 o C in atmospheric air, by repetitively exposing the specimen to thermal cycles of 2 hr-heating and subsequent quenching to room temperature. The coating displayed good cyclic oxidation resistance up to 800 o C, with relatively small weight gains, but above 900 o C, the coating displayed a drastic diminishment in oxidation resistance, accompanied by large weight gains. Cracks were observed particularly above 900 o C throughout the oxide scale that consists of TiO 2 , Cr 2 O 3 and/or Fe 2 O 3 .

“…Coatings with higher chromium content (17-58 at.%) consisted of two phases: cubic (TiCr)N and hexagonal b-(CrTi) 2 N. Due to preferential sputtering of Cr, the chromium content decreased with increasing substrate bias voltage (see Chapter 8). The two-phase coatings were nanocrystalline and showed high hardness with a maximum in the range 3,700-3,900 Vickers at a chromium content of about 25-30 at.% and a load of 0.5 N [23]. The ternary coating TiCrN can be modified by introducing carbon to the elemental composition, which could be done by using either an additional carbon (or carbon-containing) cathode or a carbon-containing process gas.…”

“…The underlying idea is to identify film material systems that show superior performance based on spinodal decomposition, similar to the 10.2 Nitride Coatings for Wear Applications well-established TiAlN system. For the Ti-Cr-N system, only one phase, c-(TiCr)N, was identified as long as the chromium content was low (10 at.%) [23]. Coatings with higher chromium content (17-58 at.%) consisted of two phases: cubic (TiCr)N and hexagonal b-(CrTi) 2 N. Due to preferential sputtering of Cr, the chromium content decreased with increasing substrate bias voltage (see Chapter 8).…”

“…Recently, Ti-based ternary nitrides such as (Ti,Al)N, (Ti,Zr)N, and (Ti,Cr)N have gained much attention as second-phase particles in steels because of their contribution to the enhanced performance for cutting tools and machinery components, e.g., regarding wear/corrosion protection. [24][25][26][27][28] In the current work, Ti and Cr were selected as alloying elements, because both Cr and Ti, as separate alloying elements, can form nitrides that are cubic (rocksalt crystal structure), albeit of different lattice constants (a CrN = 4.13Å and a TiN = 4.23Å ). Cr and Ti have different chemical affinity for nitrogen (Ti has an affinity for N much larger than that of Cr for N).…”

The microstructure of the nitrided zone of Fe-Ti-Cr alloys, containing a total of 0.30 at. pct (Ti + Cr) alloying elements, with varying Ti/Cr atomic ratio (0.45, 0.87, and 1.90), was investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The stable TiN and CrN nitrides did not precipitate after nitriding. Instead, ultrafine, metastable, mixed Ti 1-x Cr x N nitride precipitates developed in the nitrided zone: The precipitates were of platelet morphology (length £30 nm and thickness £3 nm) and of cubic, rock-salt, crystal-structure type. The misfit strain around the nitride platelets in the ferrite matrix increases with increasing Ti/Cr atomic ratio. As a consequence, most pronouncedly for the highest Ti/Cr atomic ratio, a tetragonally distorted ferrite matrix surrounds the precipitates, as evidenced both by XRD and TEM. The amount of nitrogen taken up was determined quantitatively by measuring the so-called nitrogen-absorption isotherms. It follows that the absorbed amount of so-called excess nitrogen dissolved in the matrix and adsorbed at the nitride-platelet faces increases distinctly with increasing Ti/Cr atomic ratio. The results were discussed in terms of the dependence of misfit strain on the Ti/Cr atomic ratio and the higher chemical affinity of Ti for N than of Cr for N.
