Weld formation and microstructure properties in laser welding of TC4 titanium alloy with activating fluxes of oxides and chlorides

Cailiao gongcheng
SiO2， TiO2， NaCl， and KCl are chosen as activating fluxes for laser welding of 5 mm thick TC4 titanium alloy to increase the laser absorptivity of base material and improve weld formation.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Analysis of arc behavior and weld forming in double-wire single-arc MAG welding controlled by longitudinal magnetic field

Hanjie xuebao
As a new type of high-efficiency welding process, the magnetically controlled double-wire single-arc MAG welding has poor arc controllability and is easily affected by external interference during the welding process.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
