principles of corrosion and corrosion protection on metallic materials

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.
