Накратко на български

Многослойните нанопокрития се изследват, за да се създадат по-издръжливи защитни слоеве върху повърхностите на техническите компоненти. Това помага за намаляване на износването, корозията и умората на материалите, изложени на тежки условия в индустрията.

Hierarchical Surface Protection, A New Paradigm Toward Functional Multi-Nano-Layered Coatings

What is the issue being addressed? The proposal introduces the concept of Hierarchical Surface Protection (HSP) to develop ultra-durable Functional Multilayer Coatings (FMCs) by combining the strengths of single-layer coatings without compromising weaknesses. It aims to pioneer design principles for hierarchical surface protection, addressing the lack of theoretical understanding and reliable deposition guidelines in the field. Why is it important for society? Engineering components are constantly exposed to complex environmental and service stresses, leading to material surface degradation such as wear, corrosion, and fatigue. Coating techniques have evolved over time to protect material surfaces, with advancements such as nanocomposite coatings and gradient coatings. Despite these developments, there remains a gap in design principles for developing multilayer coatings, hindering their optimization and widespread application. What are the overall objectives? The project's objectives include shedding light on material removal mechanisms in FMCs, establishing design principles for optimized coatings, and correlating research outcomes with industrial applications. These objectives collectively aim to advance the understanding of multi-layer coatings and facilitate their integration into industrial settings.

Цел на проекта

It is estimated that nearly two-thirds of the entire coating materials suffer from wear and demand annual substitution. Even a modest few percent reduction in coating failures can significantly impact energy security, energy savings, and environmental benefits. Single-layer coatings fail to sufficiently protect components surface under harsh conditions. Recent progress in the field of “Materials-by-Design” open entirely new possibilities to “hierarchically” protect surfaces by designing functionally-gradient multi-layer coatings. ”. Multi-layer coatings have been a key advancement in extending the lifetime of the wear-resistant coatings for different applications. However, progress toward this scientific resolution has been slowly progressing on an empirical basis. Theoretical understanding and design principles for optimizing the performance of multi-layer coatings are very limited. This proposal aims to take a leap forward to understand and predict material removal mechanisms in multi-layer coatings using a complementary set of computer simulations and validating experiments. Specifically, the research seeks to hierarchically protect material surfaces by tailoring and optimizing the material gradient and layer architecture in a multi-layer coating setup. The main objectives of this research are summarized in three key headings; First, is to shed light on the fundamental understanding of the materials removal mechanisms of Functional Multi-layer Coatings (FMCs) across scales using complementary computer simulations and experiments. This theoretical understanding does not exit today and will be pioneered as the final goal of this proposal. Second, is to establish ""design principles"" for optimizing functionally-gradient and layer-architecture coatings for ultra-low wear and self-healing capacities. Last but not least, is to link and correlate the potential industries with the prospective results.""
