(2) Electroplating technology has strong selectivity and can accurately control the area where plating is required;
(3) Electroplating technology can improve the hardness, wear resistance, corrosion resistance and aesthetics of the material.

2. Disadvantages
(1) Electroplating technology produces a large amount of pollutants during the plating process, which does not meet environmental protection requirements;
(2) The plating quality of electroplating technology is greatly affected by the surface state of the material and process parameters;
(3) The thickness and uniformity of the electroplating technology are limited and cannot be used in some high-precision application scenarios.

Ⅲ. Selection and Applicability of Laser Cladding and Electroplating Technology
Laser cladding technology and electroplating technology have their own advantages and disadvantages. The appropriate technology should be selected according to the specific application scenario. Laser cladding technology is more advantageous in large-area plating and environmental protection requirements are high; electroplating technology is more suitable in situations where precision plating is required on small parts. In addition, with the improvement of environmental protection and energy-saving requirements, laser cladding technology will be more advantageous.
