[0002] Contacts are components in electrical equipment used for contact and transmission of current. They are usually found in devices such as switches, relays and circuit breakers. They are usually made of conductive materials and need to ensure good conductivity and wear resistance during design. During operation, contacts close or disconnect the circuit through physical contact to ensure the normal operation of the equipment. In the design, the shape and material selection of the contacts are crucial to ensure the reliability and stability of the equipment during long-term use. Existing contact support devices enhance the corrosion resistance of their surface by applying a wear-resistant coating on the outside. However, the uniformity and adhesion of the coating may be affected by the construction process, resulting in unstable protection effect. At the same time, the wear-resistant coating wears or peels off and requires regular maintenance or replacement, which is inconvenient to operate.
