This paper reports the production of Ni–Zn multilayer alloy coating to improve the anticorrosive behavior of the mild steel material. The deposition technique follows the square wave current pulse technique. Initially, the effect of current densities on the anticorrosive behavior of the Ni–Zn was investigated. Later, the current densities were opti...

... scanning electron microscopy (SEM) images of the Ni-Zn alloy deposited at different c.d. is as shown in Fig. 3. It is noticed that the surface morphology of the coatings changes drastically with an increase of c.d. The coarse grain structure was observed at a lower current density of 1 A dm −2 . This is attributed to the relatively high Zn content in the deposit as compared to higher c.d coatings. With the increase of current density, a change ...

Cathodic arc evaporated Ti1−xAlxN coatings were deposited on a Nimonic c-263 superalloy and tested under low temperature hot corrosion conditions. Treated with a MgSO4/Na2SO4 salt-mixture, all samples were annealed at 700 °C in a 2800 ppm(volume) SOx-rich atmosphere for 1, 5, 15 and 30 h. A significantly reduced corrosion severity was exhibited by...
