ANODIC OXIDE COATING WITH HIGH TEMPERATURE TOLERANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18316530 titled 'ANODIC OXIDE COATING WITH HIGH TEMPERATURE TOLERANCE

Simplified Explanation: The patent application describes an enclosure for an electronic device that includes a titanium-aluminum clad substrate with an anodic oxide coating. The coating has specific characteristics that allow it to withstand high temperatures without cracking or crazing.

  • The enclosure for an electronic device includes a titanium-aluminum clad substrate.
  • An anodic oxide coating is applied to the substrate.
  • The coating has a density between about 2.1 g/cm and 2.4 g/cm.
  • The coating has a maximum porosity between about 21% and 31%.
  • The coating can withstand temperatures over 150°C without cracking or crazing.

Potential Applications: 1. Electronic devices requiring high-temperature resistance. 2. Aerospace industry for components exposed to extreme temperatures. 3. Automotive industry for engine components. 4. Industrial equipment in high-temperature environments.

Problems Solved: 1. Cracking and crazing of coatings at high temperatures. 2. Maintaining structural integrity in extreme conditions. 3. Ensuring longevity of electronic device enclosures.

Benefits: 1. Enhanced durability in high-temperature environments. 2. Extended lifespan of electronic devices. 3. Improved performance under extreme conditions.

Commercial Applications: Title: High-Temperature Resistant Enclosures for Electronic Devices This technology can be utilized in the manufacturing of electronic devices, aerospace components, automotive parts, and industrial equipment. The market implications include increased reliability and longevity of products in high-temperature environments.

Questions about High-Temperature Resistant Enclosures: 1. How does the anodic oxide coating contribute to the high-temperature resistance of the enclosure? 2. What are the specific advantages of using a titanium-aluminum clad substrate in electronic device enclosures?
