“…The measure of adhesion is the value of the critical load Lc, from which the peeling of the coating within the limits of the scratch track and the destruction of its edges begins. Currently, microscratch testers are also used, in which the Rockwell indenter radius is 25…100 μm, and the load is from units of mN to 30 N, and nanoscratch testers, in which the indenter radius is 1…25 μm, and the load is from 10 μN to several mN [72]. Such a wide range of testing conditions makes it difficult to compare the adhesion of DLC coatings [73], given the dependence of the Lc measurement results on the indenter tip radius [74].…”

Diamond-like carbon (DLC) coatings are used to improve the quality of industrial products due to a wide range of exceptional physical, mechanical and tribological properties. Problems that limit the scope of application of hard non-hydrogenated DLC coatings with properties closest to those of diamond are considered. The scientific literature is reviewed devoted to improving the characteristics of DLC-based wear-resistant coatings. The approaches currently used to reduce internal compressive stresses, improve adhesion to the substrate, and increase the strength of coatings are analyzed. Aspects of optimization of deposition parameters, doping, constructing the gradient and multilayer structure are considered. Based on the generalization of the results of the reviewed publications, a conclusion is made about the advantages of using coatings with a multilayer structure. A promising design undoped multilayer DLC coatings with high protective properties is discussed.

“…Development of a wide variety of mechanical and tribological tests as well as various instruments and equipment enabled the researchers to measure different properties and explore the mechanical/tribological response of materials. These techniques should be accurate, effective and repeatable in order for a design engineer to use them either for further optimization of materials in full production or finding and developing novel structural materials [167,168]. Some typical methods are briefly mentioned below.…”

“…Overall, the extrinsic nature of hardness as a materials property should be considered in investigations. This is because factors such as loading mode, indenter shape, and the size of the applied load can greatly affect the hardness values [167]. A compilation of hardness data for MCrAlY-based composite coatings is shown in Figure 13.…”

The application of metal-matrix composite coatings for protecting and improving the service life of sliding components has demonstrated to have the potential of meeting the requirements of a diverse range of engineering industries. Recently, a significant body of research has been devoted to studying the mechanical and tribological performance of dispersion-strengthened MCrAlY coatings. These coatings belong to a class of emerging wear-resistant materials, offering improved properties and being considered as promising candidates for the protection of engineering structural materials exposed to tribological damage, especially at elevated temperature regimes. This paper attempts to comprehensively review the different reinforcements used in the processing of MCrAlY-based alloys and how they influence the mechanical and tribological properties of the corresponding coatings. Furthermore, the major fabrication techniques together with their benefits and challenges are also reviewed. Discussion on the failure mechanisms of these coatings as well as the main determining factors are also included. In addition, a comprehensive survey of studies and investigations in recent times are summarized and elaborated to further substantiate the review.

“…The ultimate goal of developing and applying atomistic/continuum coupling approaches is to combine atomic-level accuracy with macroscale efficiency in solving material problems in engineering. By complementing nano/microscale experiments [207,208], these state-of-the-art multiscale materials modelling methods have the potential to provide enhanced reliability in linking processing, structure, property, and performance on the length and time scales necessary for discovery, design, development, and deployment of novel materials for the future. Key tasks ahead involve both methodologies and applications, which should progress hand in hand.…”

Dislocations and heat conduction are essential components that influence properties and performance of crystalline materials, yet the modelling of which remains challenging partly due to their multiscale nature that necessitates simultaneously resolving the short-range dislocation core, the long-range dislocation elastic field, and the transport of heat carriers such as phonons with a wide range of characteristic length scale. In this context, multiscale materials modelling based on atomistic/continuum coupling has attracted increased attention within the materials science community. In this paper, we review key characteristics of five representative atomistic/continuum coupling approaches, including the atomistic-to-continuum method, the bridging domain method, the concurrent atomistic-continuum method, the coupled atomistic/discrete-dislocation method, and the quasicontinuum method, as well as their applications to dislocations, heat conduction, and dislocation/phonon interactions in crystalline materials. Through problem-centric comparisons, we shed light on the advantages and limitations of each method, as well as the path towards enabling them to effectively model various material problems in engineering from nano-to mesoscale.
