Thermodynamic Aspects of Coating Preparation, Especially for Corrosion Protection

Dear Colleagues,

The thermodynamic aspects of coating preparation are specific and challenging issues for many reasons. In most coating depositions, the energy fluxes carried by the particles to the coating site are extremely high, and the process is extremely fast and takes place under a state of significant temperature rise and considerable thermodynamic imbalance. The properties of such types of coatings also differ significantly from the properties of the same material in a large volume. In practice, the required properties of the prepared coating are most often only estimated on the basis of empirical and experimentally obtained knowledge. An important contribution to the targeted research of coating preparation is the thermodynamic aspect, especially with regard to the thermodynamics of thin, super-thin, hard, and super-hard layers. The technologically set temperature does not correspond to the temperature distribution in the applied layers; therefore, the study of enthalpy/entropy for different types of coatings on different types of substrates and with different depositions can help to predict and solve the main coating problems. For this Special Issue of Coatings, contributions will be welcome on both theoretical thermodynamics and experimental works dealing with the measurement of the temperature dependencies of coating formation. Works focused on researching tool coatings resistant to extreme temperatures and friction with the formation and propagation of thermal fatigue cracks are also considered very beneficial. Thermodynamically unstable state is the primary cause of corrosion for most metals. Thermodynamics also provides important information about the course of spontaneous corrosion process, it can predict whether the reaction will take place under given conditions.

Potential topics for this Special Issue are as follows:

• Research of the thermodynamic properties of layers (especially of thin, super-thin, hard, and super-hard layers);
• Research of enthalpy/entropy for different types of coatings;
• Research on tool coatings resistant to extreme temperatures;
• Measurement of the temperature dependencies of coating formation;
• Thermodynamic aspects of corrosion;
• Thermodynamic conditions of the formation of anticorrosive coatings.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.
