Synthesis of functionally graded nano Al2O3-Ni composite coating by pulse electrodeposition

- We used changing of pulse parameters during electrodeposition for the first time to synthesis a functionally graded Ni-Alumina composite coating.
- The duty cycle shows strongest influence on the fabrication of functionally graded coatings.
- Changing of the duty cycle from 90% to 10% at fixed frequency of 10 Hz is the optimum condition for production of functionally graded Al2O3-Ni coating.
