Prediction and identification of point defect fingerprints in X-ray photoelectron spectra of TiN with 1.18 1.37

Pavel Ondračka, Pauline Kümmerl, Marcus Hans +5

We investigate the effect of selected N and Ti point defects in 1 TiN on N 1s and Ti\,2p binding energies (BE) by experiments and ab initio calculations. X-ray photoelec…

The effect of elastic-plastic mismatch and interface proximity on the fracture toughness of Ti-TiN thin films

Nidhin George Mathews, Aloshious Lambai, Marcus Hans +3

Magnetron sputtered titanium nitride (TiN) thin films are widely used as protective coatings due to their high hardness, but suffer from inherent brittleness and low fracture tough…

Designing artificial zinc phosphate tribofilms with tailored mechanical properties by altering the chain length

Sebastian Lellig, Subisha Balakumar, Peter Schweizer +9

Zinc dialkyldithiophosphate (ZDDP), as the most prominent lubrication additive, forms tribofilms consisting primarily of zinc phosphate glasses containing sulfides. As sulfur is li…

Microscale deformation of intermetallic-Mg interface under shear loading

Anwesha Kanjilal, Shamsa Aliramaji, Deborah Neuß +4

While intermetallic (IM)-metal interfaces in metallic alloys are critical for tuning mechanical properties, they can also act as failure sites, underscoring the importance of deter…

An atomic-scale view at Fe4N as hydrogen barrier material

Aleksander Albrecht, Sang Yoon Song, Chang-Gi Lee +9

Hydrogen, while a promising sustainable energy carrier, presents challenges such as the embrittlement of materials due to its ability to penetrate and weaken their crystal structur…
