... on the corrosion performance of Thermal Spray Aluminium (TSA) Coating obtained by twin-wire arc spraying. Cylindrical electrodes (12 mm diameter) were machined from an S355 steel rod and coated with 300 µm thick TSA (AA 1050). An analytical rotator was employed for testing the coupons at 50 rpm and 600 rpm for 10...
