“…An example of this is seen in Figure 4, illustrating the wear of a monolithic TiAlN-based ceramic coating from standardised scratch testing [55]. Different coating fracture modes such spallation, buckling, transverse/lateral cracking and delamination can identified for correlating adhesive/cohesive failures under different loading conditions.…”

“…( e ) Three deformation modes are observed in the 20 at.-%Ti–80 at.-%Al coating shown in ( b/c ): (1) Lateral cracks, (2) Transverse cracks with chipping and buckling spallation, and (3) Coating fragment detachments at the rim of the scratch and recovery spallation at the two edges of the scratch. The 20 at.-%Ti–80 at.-%Al coating exhibits gross spallation, while the 33 at.-%Ti–67 at.-%Al coating shows no gross spallation [55]. …”

The value and impact that ceramic coatings have had in the development of modern mechanical systems and protection of components exposed to harsh environments are often overlooked and understated. Modern equipment must be capable of withstanding substantial attrition, impact damage, erosion and corrosion that degrades materials across a variety of applications. Ceramic coatings enable a robust protective barrier for underlying substrates that outperforms most alternative film barrier materials (i.e. polymers, metals, glasses). In this work, a comprehensive review of modern ceramic coatings for barrier protection against mechanical wear and chemical attack is discussed in detail over a large breadth of relevant topics and case studies. This review highlights many critical aspects including various coating functionalities, design architectures, processing effects, material classes and promising future directions for engineering high-performance ceramic coating.

“…However, aluminum depletion in a hightemperature water environment results in the formation of a boehmite phase that degrades the corrosion resistance of TiAlN coatings (Figure 7). To eliminate boehmite formation, the deposition of an outer TiN layer or multilayer approach based on TiN/TiAlN coating can be effective [128,129].…”

Recent Advances in Protective Coatings for Accident Tolerant Zr-Based Fuel Claddings

Zirconium-based alloys have served the nuclear industry for several decades due to their acceptable properties for nuclear cores of light water reactors (LWRs). However, severe accidents in LWRs have directed research and development of accident tolerant fuel (ATF) concepts that aim to improve nuclear fuel safety during normal operation, operational transients and possible accident scenarios. This review introduces the latest results in the development of protective coatings for ATF claddings based on Zr alloys, involving their behavior under normal and accident conditions in LWRs. Great attention has been paid to the protection and oxidation mechanisms of coated claddings, as well as to the mutual interdiffusion between coatings and zirconium alloys. An overview of recent developments in barrier coatings is introduced, and possible barrier layers and structure designs for suppressing mutual diffusion are proposed.
