Investigation of the Structure and Properties of PVD and PACVD-Coated Magnesium Die Cast Alloys

Mechanism of Cavitation Wear of a Low-Friction Composite Coating CrN+WC/C Deposed on Ferritic-Pearlitic P265GH and Austenitic X2CrNi18-9 (304L) Steels

“…Multinational industrial corporations, as well as independent or dependent scientific and industrial and research and development centre's all over the world strive to create new ultra/multifunctional engineering materials with unknown properties. Consequently, "the world of science" and "the world of industry" cooperate in achieving the goal of initiating and manufacturing new technological processes and creating new ultra/multi-functional engineering materials and unconventional structural materials subjected to cyclic-fatigue operation in highly invasive and wearable working environments [1][2][3][4].…”

“…Independent or associated scientific-research-development-industrial centres, while subjecting individual subassemblies or parts of machines or even entire devices and machines to preliminary testing and operation, must pay particular attention to the resistance of the elements working in them in terms of destruction and wear, both tribological (mechanical, fatigue, adhesive, abrasive, hydrogen and other) and non-tribological (corrosion, diffusion, cavitation, erosion, ablation and other). For the above-mentioned mechanisms, cavitation destruction and wear of engineering material's surface in particular is often omitted in engineering design, the dual/hybrid character of which has an effect on the economics and development of particular fields of economy [3][4][5][6].…”

Mechanical and Functional Properties of Cavitation Generators with PVD Functional Coatings Intended for Use in the Cavitation Environment

“…Due to the fact that the majority of parts of industrial machines and devices are exposed in their work to impact and fatigue loads working in a variable cycle, the knowledge of PVD coatings degradation mechanisms under a dynamic load is especially vital. PVD technologies have been used successfully for coatings resistant to wear deposited onto the surface of constructional materials [1,2]. PVD coatings significantly improve the impact and fatigue strength and resistance to cavitation wear.…”

“…Moreover, a coating degradation mechanism is dictated by mechanical properties such as: Young's modulus, hardness and adhesion, as well as by the substrate's (core's) properties and the frequency of external interactions linked directly to the environment of work. Undoubtedly, the cavitation effect as well as the inherent cavitation wear is an issue requiring further scientific and industrial research for describing and understanding fully and comprehensively the characteristics of the undesired issue such as cavitation wear and the accompanying phenomenon of degradation of the exploited surfaces of engineering materials in the form of constructional parts [1][2][3].…”

Characteristics of Hard Coatings on AZ61 Magnesium Alloys

“…Currently, the CVD (Chemical Vapour Deposition), and PVD (Physical Vapour Deposition) methods play an important role in the industrial practice among many techniques improving the life of materials [11] to [17]. The PVD techniques are currently commonly used for improving the mechanical and functional properties of a wide range of engineering materials [18] to [20]. Thanks to the relatively low PVD process temperature, other than the CVD processes there is no risk of losing the properties acquired during the heat treatment of the coated materials.…”
