principles of corrosion and corrosion protection on metallic materials
| Code | CE105 |
Description:
- Corrosion damage to metallic components causes considerable economic and technical damages.
- The issue of corrosion and corrosion protection therefore plays an important role in technical training.
- The CE 105allows a variety of factors that influence corrosion processes to be investigated in parallel.
- Eight glass vessels are available to do this.
- They allow different materials to be compared under different conditions.
- The required electrolyte solution is added to the vessels.
- Up to six specimens can be attached to the cover of each vessel and these are immersed in the solution.
- It is possible to connect specimens to an electrical conductor to investigate local elements and the principle of sacrificial anodes.
- An adjustable power pack allows an external voltage to be connected.
- This counters the current flow between precious and base metals in local elements.
- As result the corrosion rate of the baser metal is reduced.
- A diaphragm pump conveys ambient air into the electrolyte solution as required.
- Flow control valves can be used to individually adjust the gas flow rate for each vessel.
- It is also possible to feed other gases provided by the laboratory into the electrolyte solution.
- A pH meter is included to allow the influence of the electrolyte solution on corrosion processes to be investigated and compared.
