Thermal Properties of Sulphuric Acid Anodic Coatings

Click For Summary
SUMMARY

A 25-micron sulphuric acid anodic coating begins to break down at temperatures around 135°C, as evidenced by a significant drop in its electrical properties. This degradation occurs due to the thermal instability of the coating at elevated temperatures. Users should monitor the thermal limits of anodic coatings to ensure optimal performance in high-temperature applications.

PREREQUISITES
  • Understanding of anodic coating processes
  • Knowledge of thermal properties of materials
  • Familiarity with sulphuric acid anodizing techniques
  • Basic principles of electrical conductivity in coatings
NEXT STEPS
  • Research the thermal stability of anodic coatings at various thicknesses
  • Investigate alternative anodizing methods for higher temperature resistance
  • Learn about the effects of temperature on electrical properties of coatings
  • Explore testing methods for evaluating coating performance under thermal stress
USEFUL FOR

Materials scientists, coating engineers, and professionals involved in the production and application of anodic coatings, particularly in high-temperature environments.

Hi,

Can anyone tell me at what temperature a 25micron sulphuric acid anodic coating will start to breakdown. I have noticed that after exposure to 135°C the electrical properties of the coating have dropped drastically.

Regards
Dan
