“…In the cathodic arc deposited system, the coating columnar structure, and formation of voids and porosity due to the entrance of macroparticles (MPs) could facilitate the penetration of the corrosive media from the defects and holes into the coating/substrate interface [25,31,32]. This could form small galvanic cells at the interface and accelerate the corrosion rate.…”

Multilayer CrN/CrAlN coatings were deposited on the 420-SS by the cathodic arc evaporation system with different duty cycles of bias-voltage. The deposited films were characterized by XRD and FESEM techniques. Mechanical, electrochemical, and surface properties of deposited films were studied by nano-indentation, electrochemical, and AFM analysis. Microstructure investigation confirmed the formation of adhesive and dense nanostructure multilayer film.Increasing the duty cycle led to the decrease in the coating grain size and promoted the hardness to 34.1 ± 4 GPa. A clear reduction of size and distribution of macroparticles was observed by using large repulsive force at a high duty cycle. By increasing the duty cycle, the coating deposition rate was increased from 1.23 to 1.38 µm/h and the surface roughness was decreased from 155 to 70 nm. The lower corrosion current density was obtained for the film applied at the 40% duty cycle (0.59 µA cm −2 ), which was about 10-order of magnitude less than the substrate.

“…There are two ways to obtain polycrystalline TiAl alloy films: crystallized films directly deposited on heated substrates [6,7] and the crystallization operation for amorphous films deposited on unheated substrates. [8,9] Since the latter method is the frequently-used way to fabricate TiAl alloy thin films, the crystallization characteristic of amorphous TiAl films has fascinating interest.…”

Crystallization kinetics of magnetron-sputtered amorphous TiAl alloy thin films is investigated by differential scanning calorimetry through isothermal analysis and non-isothermal analysis. In non-isothermal analysis, the Kissinger method and the Ozawa method are used to calculate the apparent activation energy and local activation energy, respectively, in the crystallization processes of amorphous TiAl thin films. Furthermore, the crystallization mechanism is discussed from the investigation of the Avrami exponent by isothermal analysis. In addition, x-ray diffraction is utilized to reveal the grain orientation and evolution during the crystallization of TiAl thin films.
