“…However, the highest operational characteristics of manages to reach by engineering composite multilayer periodic structures. Among the most investigated in this direction compositions can be attributed TiN/Cu [20], TiN/CrN [21], HfN/VN [22], TiN/-Ti [23], (Ti, Al)N/VN [24,25] and TiN/VN [25,26], etc., from materials as compatible with each other, so [27] and incompatible [29]. Results of investigations are prove that multicomponent and especially multilayer coatings considerably exceed coatings TiN by properties [7,19].…”

The possibilities of structural engineering of multi-period vacuum-arc coatings based on nitrides of transition metals Ti, Cr, Mo, and Zr have been investigated by structural studies (X-ray diffraction and electron microscopy) in combination with measurement of hardness by indentation. The formation of phases with a cubic crystal lattice under nonequilibrium conditions under vacuum arc method of production. The supply of a negative bias potential of-200V in mononitrides leads to the predominant formation of texture of crystallites with the [111] axis. The introduction of thin (about 10 nm) metal layers leads to a decrease in texture perfection [111] and texture formation [100]. This effect is associated with a change in the stress-strain state of nitride layers. It is determined that the composite multiperiod coatings (Me1N/Me2N)/(Me1/Me2) have a greater hardness and greater resistance compared to MeN/Me. For a multiperiod system with damping metal layers-(ZrN/CrN)/(Zr/Cr), superhard coatings with a hardness of 46 GPa were obtained.

AZ91D, a die‐casted alloy, offers several benefits (better saltwater corrosion resistance, suitable castability, and good atmospheric stability) over other grades of magnesium alloy. However, it cannot overcome the challenging requirements of advanced applications in its current form. Extensive research in coating technologies is crucial in enhancing the performance of AZ91D alloy in highly corrosive environments (coastal and marine, industrial, farm, etc.). The high corrosion resistance of AZ91D for various applications is achievable through the deposition of different materials. Developments in coating materials and techniques, with their influence on the corrosion protection behavior of AZ91D alloy, over the last decade (2012–2022), are focused on in this study. It is observed that composite, biodegradable, and self‐healing coatings are gaining popularity. The transition in the coating technology, from conventional to self‐healing coating materials and from conventional to environment‐friendly coating techniques, is a vital part of this discussion. This review further explores how different additives, pre‐treatments, post‐treatments, and corrosion inhibitors affect the corrosion performance of coatings. This study helps select the optimum coating material for AZ91D magnesium alloy to fulfil a specific application requirement and guides toward technological developments in this segment.

“…Alloys treated in this way could be used to produce moving parts for machines and devices [ 6 ], for instance lightweight sliding elements in advanced optical devices for aviation and aerospace industries. For more than two decades, the use of nitride surface layers in magnesium alloy surface engineering has attracted the attention of various authors [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Nitride layers on magnesium alloys are usually produced using PVD methods, (magnetron sputtering or arc evaporation) as they are the only alternative methods that allow precise control of layer thickness, roughness, and porosity.…”

“…Nitride layers on magnesium alloys are usually produced using PVD methods, (magnetron sputtering or arc evaporation) as they are the only alternative methods that allow precise control of layer thickness, roughness, and porosity. In earlier investigations, these methods were used to produce surface layers of various nitrides, in particular of metals such as aluminum, chromium, and titanium [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ], while recent research has focused mainly on titanium nitride-based layers [ 13 , 14 , 15 , 16 , 17 ], which seem to be the most prospective, due to the simultaneous high corrosion and wear resistance, combined with a relatively low susceptibility to cracking. While the nitride layers considerably improve the wear resistance of magnesium alloys, [ 8 , 11 , 16 ] their effect on corrosion resistance has usually been unsatisfactory [ 6 ], given their insufficient tightness due to porosity and structural defects, typical for PVD methods [ 20 ], which makes application impractical [ 4 ].…”

Improving the Properties of Composite Titanium Nitride Layers on the AZ91D Magnesium Alloy Using Hydrothermal Treatment

et al. 2021

Coating magnesium alloys with nitride surface layers is a prospective way of improving their intrinsically poor surface properties; in particular, their tribological and corrosion resistance. These layers are usually produced using PVD methods using magnetron sputtering or arc evaporation. Even though the thus-produced layers significantly increase the wear resistance of the alloys, their effects on corrosion resistance are unsatisfactory because of the poor tightness, characteristic of PVD-produced products. Tightness acquires crucial significance when the substrate is a highly-active magnesium alloy, hence our idea to tighten the layers by subjecting them to a post-deposition chemical-hydrothermal-type treatment. This paper presents the results of our experiments with a new hybrid surface engineering method, using a final tightening pressure hydrothermal gas treatment in overheated steam of the composite titanium nitride layers PVD, produced on AZ91D magnesium alloy. The proposed method resulted in an outstanding improvement of the performance properties, in particular resistance to corrosion and wear, yielding values that exceed those exhibited by commercially anodized alloys and austenitic stainless 316L steel. The developed hybrid method produces new, high-performance corrosion and wear resistant, lightweight magnesium base materials, suitable for heavy duty applications.
