Influence of Silicon and Chromium on the Na₂SO₄-Induced Hot Corrosion Behavior of Titanium Alloys

Crystals, 2023
Titanium alloys are widely used as construction materials in the aerospace and automotive industries. They have many advantages but also have limitations related to their susceptibility to high-temperature oxidation and hot corrosion.

Nanocalorimetry of Nanoscaled Ni/Al Multilayer Films: On the Methodology to Determine Reaction Kinetics for Highly Reactive Films

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
Free‐standing Ni/Al multilayer thin films are investigated with a novel commercial nanocalorimeter and a conventional calorimeter. The Kissinger analysis shows a monotonic Arrhenius behavior over the entire five orders of magnitude of heating rates for all thermal events.

Method of protecting a surface with a silicon-slurry/aluminide coating [PDF]

, 1982
A low cost coating for protecting metallic base system substrates from high temperatures, high gas velocity oxidation, thermal fatigue and hot corrosion is described. The coating is particularly useful for protecting vanes and blades in aircraft and land

RuAl Thin‐Film Deposition by DC Magnetron Sputtering

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
The synthesis and influence of deposition parameters on the corresponding microstructure of single‐phase RuAl in B2 structure is examined via transmission electron microscopy analysis and X‐ray diffraction with additional pole figure measurements. These are correlated to mechanical properties of the magnetron‐sputtered thin films.

Development and characterization of in‐situ nickel aluminide reinforced Al‐Si matrix composites by stir casting

Engineering Reports, Volume 6, Issue 12, December 2024.
The graphical abstract demonstrates that adding 9 wt% nickel to an Al‐Si matrix composite increases hardness by 25.93%, tensile strength by 40.3%, and density by 6.01%, but decreases impact strength by 50% compared to the A413 alloy. It includes SEM images, a stir casting schematic, and data on tensile and impact behavior.

Causal discovery to understand hot corrosion

Materials and Corrosion, Volume 75, Issue 12, Page 1639-1651, December 2024.
Causal discovery has been applied to a small hot corrosion data set to explore the factors influencing the mechanism. The left part of the picture shows the sequence of the applied methodology, from the data processing to obtaining the relationship between the factors influencing hot corrosion.
