“…2a, a higher density of regions of high strain or cracks (red streaks) in the DIC image corresponding to the wave crests compared with the troughs can be clearly seen. Thicker films fracture before similar thinner films, and thicker films have lower average crack densities (larger average crack spacing) 16–20. A similar result was observed in the wavy lines by the different crack densities.…”

Printing of metallic films has been preferred over vacuum technologies for roll-to-roll processes because of faster processing times and lower processing costs. Films can be produced by depositing inks containing suspended metallic particles within a solvent and then heating the films to both remove the solvent and sinter the particles. The resulting printed structure and electrical and mechanical behavior of the printed films has been studied to better understand their electro-mechanical response to loading and eventual brittle fracture. This study evaluated the electro-mechanical behavior of 1.25-μm printed Ag films using in situ resistance and in situ imaging methods. Digital image correlation was utilized with confocal laser scanning microscope images to better visualize crack initiation during tensile straining. This technique showed that cracks initiated earlier in the thicker areas of the film (crests) than in lower areas (troughs) because of a higher density of printing defects and the increased thickness.

“…Nevertheless, weak adhesion and large modulus mismatch between the polymer substrate and the conductor film render these approaches to improve strain tolerance insufficient for producing highly stretchable devices. Further details about the challenges of these approaches are available in previous reports [40][41][42][43][44][45][46][47] .…”

“…The uses for titanium in industry are growing faster than ever before, as a material that is both strong and lightweight. Titanium also has many outstanding properties such as being excellent in corrosion resistance (even in seawater), high in strength (~1800 MPa), high in electric resistance, and excellent in biocompatibility [1][2][3]. These properties allow it to be used in numerous applications in the aerospace industry, building industry, sports material industry and as implants in a number of surgical procedures [4][5][6].…”

A series of the multicomponent thin films (binary: Ti-C; Ti-Ag and ternary: Ti-C-Ag; Ti-C-Al) were fabricated by Thermionic Vacuum Arc (TVA) technology in order to study the wear resistance and the anticorrosion properties. The effects of Ti amount on the microstructure, tribological and morphological properties were subsequently investigated. TVA is an original deposition method using a combination of anodic arc and electron gun systems for the growth of films. The samples were characterized using scanning electron microscope (SEM) and a transmission electron microscope (TEM) accompanied by selected area electron diffraction (SAED). Tribological properties were studied by a ball-on-disc tribometer in the dry regime and the wettability was assessed by measuring the contact angle with the See System apparatus. Wear Rate results indicate an improved sliding wear behavior for Ti-C-Ag: 1.31 × 10 −7 mm 3 /N m (F = 2 N) compared to Ti-C-Al coating wear rate: 4.24 × 10 −7 mm 3 /N m. On the other hand, by increasing the normal load to 3 N an increase to the wear rate was observed for Ti-C-Ag: 2.58 × 10 −5 mm 3 compared to 2.33 × 10 −6 mm 3 for Ti-C-Al coating.
