A new approach to the simultaneous measurement of hydrogen evolution reaction (HER) and elemental dissolution rates is presented applied galvanized steel coatings with HCl solution. Dissolution profiles revealed several kinetic regimes including intact coating, nanometric Fe2Al5 intermetallic layer, corrosion substrate. The HER Zn were in excellent agreement, quantities interfacial Fe Al consis...

As a solid-state bonding technology, ultrasonic welding (USW) has the characteristics of green energy saving and environmental friendliness. It is more suitable for joining dissimilar metals than other technologies. The aluminum-to-steel USWed joint been widely used in automotive aviation industries. Currently, there no review literature report on USW. main physical phenomena USW process includ...
