Production of intermetallics’ and ceramics’ protective coatings can be simple, beneficial, and highly predictable. However, comprehensive possibilities for the synthesis and application of this type of coatings, also with the use of intermediate layers, are limited by the technological conditions of the synthesis process and coexisting physical phenomena. The physicochemical, thermophysical, and structural properties of the coating materials can frequently be subjected to changes in situ in the synthesis conditions—also with the possibility of formation of new ones phases in relation to the feedstock powder material.
This Special Issue will focus on various conventional synthesis methods of different intermetallics and ceramics coatings with thermal (D-gun, HVOF, ARC and plasma) spraying, cold spraying, PVD, CVD, and additive manufacturing processes (LENS and other). The main subtopics include experimental research on coating production and analysis of physicochemical and thermo-gasokinetic phenomena under various conditions of the synthesis processes relating to a specific method of production.
A unique problem to be considered is analyzing the influence of synthesis conditions on mechanisms of deformation and strengthening of nominally brittle intermetallics and ceramics phases during synthesis processes of the powder particles, especially during the supersonic flow of stream at D-gun spraying and HVOF process. This description includes a comprehensive analysis of the structural transformation of powder particles into elementary grains in the synthesized structure of intermetallic, ceramic. and cermet coatings.
The analysis of the problem can take into account the synthesis conditions (such as the impact of particle velocity, the temperature, and dynamic pressure of the gaseous stream) on the chemical and phase, composition, crystallographic and morphological microtexture, size of the crystallites, and the state of the grain boundaries in the particles and obtained coatings, as well as the degree of superstructure disorder with identification of nano/ultrafine grain and subgrain areas, dislocation, and antiphase domains. In the thermophysical property analysis, both for the feedstock powder material and coatings, other phenomena are subject to consideration (i.e., the exchange of momentum and convective heat transfer, as well as the thermal effects of phase changes after melting of powder particles), including analytical and numerical analysis.
The conducted considerations may also concern the analysis of the feedstock powder properties used in the synthesis process of the coatings, with taking into account the limitations of heat transport efficiency resulting mainly from the conditions of the synthesis process and the structural conditions of the powder particles, which often show an inhomogeneous multiphase structure also involving pores.
It is also important to analyze the functional properties of the produced coatings, including the residual stress, adhesive strength, thermal stability, corrosion resistance, and abrasive wear mechanisms, as well as the geometric structure analysis of the surface layer of the coatings together with fractal characteristics using the root mean square (RMS) method.
Thus, in this Special Issue, it will be possible to make a comprehensive assessment of how specific synthesis conditions using different methods can affect the structure and performance properties of multiphase intermetallic, ceramic, and cermet coatings in terms of their comprehensive use.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.
