“…Previous studies showed that AlCrSiN possessed good thermal stability and oxidation resistance because of the formation of the epitaxial growth structure, which inhibited atomic diffusion. The nanocomposite coatings synthesized by amorphous silicon nitride could provide a stable phase and limited grain growth in nanocrystal AlCrN at high temperature [44,45,46]. However, in this study, the non-duplex-treated AlCrSiN sample only resisted 200k impacts at 500 °C.…”

Surface modification of steel has been reported to improve hardness and other mechanical properties, such as increase in resistance, for reducing plastic deformation, fatigue, and wear. Duplex surface treatment, such as a combination of plasma nitriding and physical vapor deposition, achieves superior mechanical properties and resistance to wear. In this study, the plasma nitriding process was conducted prior to the deposition of hard coatings on the SKH9 substrate. This process was done by a proper mixture of nitrogen/hydrogen gas at suitable duty cycle, pressure, and voltage with proper temperature. Later on, the deposition of gradient AlCrSiN coatings synthesized by a cathodic-arc deposition process was performed. During the deposition of AlCrSiN, CrN, AlCrN/CrN, and AlCrSiN/AlCrN were deposited as gradient interlayers to improve adhesion between the coatings and nitrided steels. A repetitive impact test (200k–400k times) was performed at room temperature and at high temperature (~500 °C) to assess impact resistance. The results showed that the tribological impact resistance for the synthesized AlCrSiN increased because of a progressive hardness support. The combination of plasma nitriding and AlCrSiN hard coatings is capable of increasing the life of molding dies and metal forging dies in mass production.

“…Therefore, the requirements of protective coatings are high hardness, smooth surface morphology, high thermal stability, adequate adhesion, long cyclability, and chemical inertness. Following the successful utilization of noble metal alloys [4][5][6][7][8][9][10][11] and carbon films [12,13], transition metal nitride films [14][15][16][17][18][19][20][21][22][23], which offer cost reduction and process control benefits, have become candidates for protective coatings. The oxidation resistance levels of some transition metal nitrides have been improved by the introduction of Si; in particular, improvements to Ti-Si-N [24][25][26] and Zr-Si-N [27][28][29] coatings have been reported.…”

Bonding Characteristics and Chemical Inertness of Zr–Si–N Coatings with a High Si Content in Glass Molding

et al. 2018

High-Si-content transition metal nitride coatings, which exhibited an X-ray amorphous phase, were proposed as protective coatings on glass molding dies. In a previous study, the Zr-SiN coatings with Si contents of 24-30 at.% exhibited the hardness of Si 3 N 4 , which was higher than those of the middle-Si-content (19 at.%) coatings. In this study, the bonding characteristics of the constituent elements of Zr-SiN coatings were evaluated through X-ray photoelectron spectroscopy. Results indicated that the Zr 3d 5/2 levels were 179.14-180.22 and 180.75-181.61 eV for the Zr-N bonds in ZrN and Zr 3 N 4 compounds, respectively. Moreover, the percentage of Zr-N bond in the Zr 3 N 4 compound increased with increasing Si content in the Zr-SiN coatings. The Zr-N bond of Zr 3 N 4 dominated when the Si content was >24 at.%. Therefore, high Si content can stabilize the Zr-N compound in the M 3 N 4 bonding structure. Furthermore, the thermal stability and chemical inertness of Zr-SiN coatings were evaluated by conducting thermal cycle annealing at 270 • C and 600 • C in a 15-ppm O 2-N 2 atmosphere. The results indicated that a Zr 22 Si 29 N 49 /Ti/WC assembly was suitable as a protective coating against SiO 2-B 2 O 3-BaO-based glass for 450 thermal cycles.

Cam, keşfedildiği dönemden günümüze dek çok farklı uygulama alanlarına sahip olmuş ve her geçen gün gelişen teknoloji sayesinde ilerleme kaydetmiştir. Cam yüzeylere uygulanan kaplama yöntemleri sayesinde, üretilen cam malzemeler mevcut özelliklerinin ötesinde daha fazla işlevsellik edinmişler, böylece, dış ortam koşullarına karşı (ısı, ışık, zararlı ışınlar, basınç) daha yüksek dayanım sergilemeye başlamışlardır. Bu çalışmada da, cam yüzey kaplamaları hakkında kısa bir tanımlama yapılmış, kaplama teknolojilerinin geçmişten günümüze tarihsel gelişiminden bahsedilmiş, örneklerle cam yüzeyine uygulanan kaplama yöntemlerinden söz edilmiş, kaplama çeşitleri üzerinde durulmuş ve yüzey kaplama teknolojilerindeki son gelişmelere değinilmiştir.
