• Mild Steel (0.3-0.8% Carbon): Enhanced strength, suitable for moderate electrolysis conditions.
• Cast Iron (2-4% Carbon): High wear resistance, potential for specific electrochemical reactions.

Preparation Techniques

Effective preparation of iron-carbon bed materials involves several methods to optimize their structure and surface properties:

1. Alloying - Utilizing metallurgical techniques to control carbon content.
2. Heat Treatment - Enhancing mechanical and thermal properties through processes like quenching and tempering.
3. Surface Coating - Applying protective layers to improve durability against electrolytic corrosion.

Electrolysis Performance

Evaluating the performance of iron-carbon materials in electrolysis is crucial. Key factors include:

• Conductivity: Higher conductivity allows for efficient current flow.
