“…The c/t-ZrO2 phase then undergoes a martensitic phase transformation to m-ZrO2, which is accompanied by a volume expansion of ~5% [18,29]. This phase evolution was reported by several authors for the ZrN [10,11,28], as well as for the ZrC system [14,15,21]. However, as it can be seen for all three samples in Figure 3, the c/t-ZrO2 phase prevails in Zone 2 and Zone 3 up to 1000 °C and is not completely transformed to m-ZrO2.…”

“…This ZrO2 phase acts as an oxygen diffusion barrier and retards the oxidation process, leading to the precipitation of free carbon. With increasing temperature, ZrO2 crystallises to c-ZrO2 or t-ZrO2; it should be noted that the differentiation between t-ZrO2 and c-ZrO2 is not possible using XRD, as the reflections appear at very similar diffraction angles [26,28]. Analogously to t-ZrO2, c-ZrO2 is unstable at lower temperatures (<1170 °C), however, both phases can be stabilised by the substitution of O 2− with C 3− ions, creating oxygen ion vacancies [17,29].…”

The oxidation behaviour of chemical vapour deposited ZrN, ZrC and ZrCN coatings was investigated using in-situ synchrotron X–ray diffraction (XRD). To obtain a precise analysis of the temperature–dependent phase evolution during oxidation, coating powders were annealed in air between 100 °C and 1000 °C. Simultaneously, 2D XRD patterns were recorded in ~2 °C increments, which were subsequently evaluated using parametric Rietveld refinement. The results were correlated with differential scanning calorimetry and thermogravimetric analysis measurements, to further illuminate the oxidation mechanism of each coating system. ZrCN exhibited the highest oxidation onset temperature, followed by ZrC and ZrN. Furthermore, ZrCN was completely oxidised at a temperature of ~720 °C, which was ~50–70 °C higher than for ZrN and ZrC. The in–situ experiments revealed a similar oxidation sequence for all three samples: first, tetragonal and/or cubic (c/t)–ZrO2 is formed, which subsequently transforms into the more stable monoclinic (m)–ZrO2 phase. ZrCN and ZrC showed a higher c/t–ZrO2 fraction than the ZrN sample at 1000 °C. Furthermore, ex–situ Raman and XRD investigations of the oxidised samples revealed the ongoing c/t–ZrO2 → m–ZrO2 phase transformation during cooling.

“…Ceramic coatings are widely deposited on substrates from metals, alloys and steels for various applications [1][2][3][4][5][6][7][8][9][10]. In particular, considerable efforts are directed at attempts to implement them for improving the functional characteristics of austenitic stainless steels [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Key challenges for the success of these endeavors are incompatibility of microstructures and properties of the materials at the metal/ceramic interfaces [13,14,, as well as residual stresses in the coatings [13,21,[52][53][54][55], causing low adhesion and their delamination from the substrates.…”

Effect of Preliminary Irradiation of 321 Steel Substrates with High-Intense Pulsed Ion Beams on Scratch Test Results of Subsequently Deposited AlN Coatings

et al. 2021

The paper presents the effect of irradiation of 321 steel substrates with a high-intense pulsed ion beam (HIPIB) on changes in functional properties of the surface layers and tribological characteristics of AlN coatings subsequently deposited above by the reactive magnetron sputtering method. The morphology of the modified surface layers, their microhardness and free surface energy levels are presented for different HIPIB energy densities. HIPIB irradiation of the substrates caused variations in the results of scratch tests combined with the acoustic emission signal processing. Their analysis has enabled concluding that the crack initiation threshold could be at least doubled for the studied coating/substrate system due to preliminary HIPIB irradiation. Finally, the obtained data were discussed, and future research directions were proposed.

“…For example, a lower substrate temperature is favorable for the formation of amorphous structures [ 23 ]. In addition, thermal annealing is an effective method to reduce intrinsic defects and change the microstructure of films [ 24 , 25 , 26 , 27 ]. In a previous study, amorphous MoS 2 films were prepared by controlling the deposition temperature and process parameters, and their internal structure was changed through vacuum thermal annealing [ 28 ].…”

Among the structural materials used in fusion reactors, amorphous materials can effectively inhibit the accumulation and growth of radiation-induced defects, thereby improving irradiation resistance. However, the application of solid lubricating materials should also consider the changes in their lubricating properties after irradiation. This study shows that the ability to inhibit the deterioration of lubricating properties is not reflected in the amorphous MoS2 film. When the ion fluence reached 4.34 × 1014 ion/cm2, its wear life was reduced by two orders of magnitude, reaching 8.2 × 103 revolutions. After the amorphous MoS2 film is vacuum annealed, its structural stability and resistance to deterioration of lubricating properties are improved. When the ion fluence reaches 1.09 × 1015 ion/cm2, for instance, the wear life of the MoS2 film annealed at 300 °C remains at 8.4 × 104 revolutions. The higher irradiation tolerance of MoS2 films comes from the reduction in intrinsic defects by thermal annealing, which increases the internal grain size and volume fraction of grain boundaries, further providing an effective sink for irradiation defects.
