COATINGS FOR GALVANIC CORROSION MITIGATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240276660 titled 'COATINGS FOR GALVANIC CORROSION MITIGATION
The patent application describes a housing design that includes a clad to prevent galvanic corrosion. The clad consists of an interior metal within an exterior metal with a lower electrical conductivity potential. An aperture in the housing allows for the insertion of an actuator or plug. A corrosion-resistant coating is applied to the interior metal at the clad interface to further prevent corrosion.
- Housing design includes a clad to prevent galvanic corrosion
- Clad consists of interior metal within exterior metal with different conductivity potentials
- Aperture in housing allows for insertion of actuator or plug
- Corrosion-resistant coating applied to interior metal at clad interface
- Coating thickness ranges from about 2 µm to about 10 µm
Potential Applications: - Industrial equipment - Marine applications - Automotive components
Problems Solved: - Galvanic corrosion prevention - Increased durability of housing components
Benefits: - Extended lifespan of housing - Reduced maintenance costs - Enhanced performance in corrosive environments
Commercial Applications: Title: Corrosion-Resistant Housing Design for Industrial Equipment This technology can be utilized in various industries such as manufacturing, marine, and automotive for durable and long-lasting housing solutions. The market implications include cost savings on maintenance and replacement parts.
Questions about Corrosion-Resistant Housing Design: 1. How does the clad prevent galvanic corrosion in the housing? The clad design with different conductivity potentials between the interior and exterior metals creates a barrier that inhibits galvanic corrosion.
2. What is the significance of the corrosion-resistant coating on the interior metal? The corrosion-resistant coating adds an extra layer of protection at the clad interface, further reducing the risk of corrosion.
Original Abstract Submitted
to eliminate galvanic corrosion, a housing includes a clad. the clad includes an interior metal disposed within an exterior metal and a clad interface. the exterior metal includes a lower electrical conductivity potential than the interior metal. an aperture can extend through the exterior metal and the clad interface and an actuator or a plug can be disposed within the aperture. the housing further includes a corrosion resistant coating disposed on a portion of the interior metal at the clad interface. the corrosion resistant coating can include a thickness between about 2 �m and about 10 �m.
