Description

technical field [0001] The invention relates to a novel nanocomposite coating synthesis process, in particular to a composite coating of electrodeposited Zr particles and a preparation method thereof. Background technique [0002] Electrodeposited metal-based composite coatings are widely used as surface modification materials or decorative materials for microelectronic devices because of their high hardness, good corrosion resistance and good wear resistance. The obtained electroplating layer must have the following characteristics: good bonding force, sufficient thickness, appropriate mechanical properties (hardness and strength), thermal disturbance resistance and corrosion resistance. Nickel-based composite plating has been applied in microelectronic devices due to its good processability, high hardness, good wear resistance and high corrosion resistance. [0003] Pure nickel plating has been widely used in microelectronic devices, packaging and decoration industries. ...
