Spraying Conductive Wear-resistant Coating

Ultrasonic spraying technology: reshaping the new benchmark of conductive wear-resistant coating on metal substrates

In the fields of electronic appliances, precision instruments, etc., metal substrates such as copper, nickel, and silver-palladium alloys have strict requirements on the conductivity and wear resistance of surface coatings. When dealing with such requirements, traditional coating processes often face problems such as high resistance and poor wear resistance. Ultrasonic spraying technology, with its innovative process, brings breakthrough solutions for the preparation of conductive wear-resistant coatings and becomes a key booster for the development of the industry.

Traditional conductive wear-resistant coating spraying processes, such as brushing and ordinary spraying, have many limitations when applied on copper, nickel, and silver-palladium alloy substrates. Brushing is difficult to ensure the uniformity of the coating, resulting in unstable resistance; the coating of ordinary spraying has weak bonding with the substrate, poor wear resistance, and pores are prone to appear inside the coating, affecting the conductive effect. In actual use, the resistance of these coatings is often difficult to reach the ideal value, and under long-term friction and wear conditions, the coating is easy to peel off, which cannot meet the performance requirements of high-end equipment.

Ultrasonic spraying technology uses the cavitation effect of high-frequency ultrasound to atomize the conductive wear-resistant coating into nano-scale tiny particles. These particles are evenly and tightly attached to the surface of copper, nickel, and silver-palladium alloy substrates under the guidance of precisely controlled airflow. Compared with traditional processes, ultrasonic spraying has smaller particle diameters and more uniform distribution, which can achieve close integration of the coating and the substrate, effectively reduce the porosity of the coating, and improve the conductivity and wear resistance. By precisely controlling parameters such as ultrasonic frequency and spraying flow, the coating resistance can be stabilized to a few tenths of an ohm, meeting the conductivity requirements of various high-precision equipment.

In actual application scenarios, ultrasonic spraying of conductive wear-resistant coatings shows significant advantages. Taking electronic connectors as an example, after ultrasonic spraying of conductive wear-resistant coatings on the surface of copper substrates, their resistance is greatly reduced, the current transmission efficiency is significantly improved, and the problem of poor contact is reduced by more than 60%; on the nickel alloy parts of precision instruments, the coating has excellent wear resistance, which reduces the wear of the parts by 70% under long-term high-frequency use, effectively extending the service life of the equipment. For electronic components with silver-palladium alloy substrates, the ultrasonic spray coating not only ensures good conductivity, but also enhances the corrosion resistance of the components in complex environments and ensures the stability of the circuit system.

In addition, the non-contact characteristics of ultrasonic spraying avoid physical damage to the surface of metal substrates such as copper, nickel, and silver-palladium alloys, protecting their original performance. The technology is also highly flexible and can freely adjust process parameters according to different substrate characteristics and usage scenarios, and adapt to a variety of conductive wear-resistant coating formulas. Cheersonic continues to upgrade the technology of ultrasonic spraying equipment and optimize the intelligence of the equipment. The intelligent monitoring system can monitor various parameters in the spraying process in real time and automatically adjust to ensure that each product can obtain high-quality conductive wear-resistant coatings.

With the continuous improvement of the requirements for the surface performance of metal substrates in various industries, ultrasonic spraying conductive wear-resistant coating technology will become the mainstream choice of the industry with its excellent performance in low resistance and high wear resistance, and continue to provide solid guarantees for the development of electronics, precision instruments and other fields.
