Special Issue Information

Dear Colleagues,

Continuous development of thermal barrier coatings and materials for high-temperature applications require a deep understanding of their mechanical and microstructural properties, especially in relation to their behaviour at elevated temperature. Mechanical testing of coatings is essential to evaluate their performance and ensure they meet the required standards for specific applications. Furthermore, precise characterization of TBC mechanical properties are crucial for structural design, performance optimization, failure prediction and service life estimation thus it is essential to assess their reliability and durability, especially at high temperature. Therefore this Special Issue aims to provide insight into novel experimental approaches dedicated to mechanical testing of TBC under their service conditions.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to):

  1. Adhesion Testing
  2. Nanoindentation
  3. Wear and Abrasion Testing
  4. Scratch Resistance Testing
  5. Fatigue and Creep Testing
  6. Impact Testing
  7. Thermal Cycling and Shock Testing

We look forward to receiving your contributions.

In this article, the structure formation and phase composition of coatings containing Cr2AlC MAX phase under the conditions of plasma spraying were studied. Mechanical mixtures of commercially available Cr3C2 and Al powders were used as a material for spraying. The amount of aluminium in the mixtures was 9 and 18 wt.%. As a result of studying physicochemical processes occurring during plasma spraying of mechanical mixtures of selected compositions, the formation of coatings containing Cr2AlC MAX phase was established, the synthesis of which occurs both at the stage of the particles flight of initial components in the plasma jet as a result of the collision and coagulation, and at the stage of a coating layer formation as a result of layering particles deformed during the collision–splats. It is shown that for the formation of a denser coating with a higher MAX phase content for spraying, it is rational to use a mixture of chromium carbide powders with 9 wt.% of aluminium. A coating with the composition 91Cr3C2-9Al (wt.%) has high corrosion resistance in operation conditions in a chloride-acetate solution, and by its indicators of corrosion resistance, is not inferior to the Cr3C2-NiCr coating, which is widely used in industry to protect parts from corrosion and wear. The obtained results show the possibility and feasibility of using mechanical mixtures of commercially available powders for the formation of coatings containing Cr2AlC MAX phase instead of expensive synthesized MAX-Cr2AlC powders.

Abstract
In this paper, 20 µm and 40 µm thick aluminide coatings were deposited on MAR-M247 nickel-based superalloy through the chemical vapor deposition (CVD) process in a hydrogen protective atmosphere for 4 h and 12 h, respectively, at a temperature of 1040 °C and [...] Read more.
In this paper, 20 µm and 40 µm thick aluminide coatings were deposited on MAR-M247 nickel-based superalloy through the chemical vapor deposition (CVD) process in a hydrogen protective atmosphere for 4 h and 12 h, respectively, at a temperature of 1040 °C and an internal pressure of 150 mbar. The effect of aluminide coating thickness on the high-temperature performance of the MAR-M247 nickel-based superalloy was examined during a fatigue test at 900 °C. After high-temperature testing, the specimens were subjected to fractographic analysis to reveal the damage mechanisms. No significant effect of coating thickness was found since the material exhibited a similar service life throughout the fatigue test when subjected to the same stress amplitude. One should stress that the coating remained well adhered after specimen fracture, confirming its effectiveness in protecting the material against high-temperature oxidation. Full article
