Abstract

For mechanically dominated load profiles, nitrides are preferred as the base material for structural and functional hard coatings, while oxide-based materials offer better protection against high-temperature corrosion (such as oxidation). Thus, when mechanical and thermal loads are combined, the nitrides used should also have excellent stability against temperature and oxidation. How to develop such nitride materials that can withstand both high mechanical and thermal loads is the focus of this review article. This is done primarily with the help of experimental and theoretical investigations of the Ti–Al–N system.

On the basis of transition metal nitride coatings, we discuss important material development guidelines for improved strength, fracture toughness as well as thermal stability and oxidation resistance. Using various superlattice coatings, we further discuss how such nanolamellar microstructures can improve both the strength and fracture toughness of hard coating materials. In addition, other concepts for improving fracture toughness are discussed, with a focus on those that can increase both fracture toughness and hardness.

The individual concepts allow to design materials to meet the ever-growing demand for coatings with a wide range of excellent properties and outstanding property combinations.

基于材料科学的指南，开发坚固的硬薄膜材料

对于以机械载荷为主的情况，氮化物是结构性和功能性硬涂层的首选基材，而氧化物基材则能更好地防止高温腐蚀（如氧化）。因此，当机械载荷和热载荷结合在一起时，所使用的氮化物还应具有出色的耐温性和抗氧化性。如何开发出既能承受高机械负荷又能承受热负荷的氮化物材料，是本综述文章的重点。在过渡金属氮化物涂层的基础上，我们讨论了提高强度、断裂韧性以及热稳定性和抗氧化性的重要材料开发指南。利用各种超晶格涂层，我们进一步讨论了这种纳米胶束微结构如何提高硬涂层材料的强度和断裂韧性。此外，我们还讨论了提高断裂韧性的其他概念，重点是那些既能提高断裂韧性又能提高硬度的概念。通过这些概念，我们可以设计出具有各种优异性能和出色性能组合的涂层材料，以满足日益增长的需求。

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
