Ni-Bi composite coatings produced by ionic co-discharge electrodeposition

Composite coatings are widely used in applications due to their excellent mechanical properties and long service life. Most recent studies have been conducted using the co-deposition of metal with oxides or ceramic particles to produce composite coatings. However, the investigation of the co-deposit...
