Wear and corrosion resistant layers

Metalmembranes fabricates integrated ceramic layers on titanium and aluminum metal products by a plasma electrolytic oxide (PEO) coating. Metalmembranes has gained considerable experience for the formation of these protective layers on various grades of aluminum and titanium. Also different reinforcement materials can be applied to give the porous layer additional functionality (Teflon, sol-gel etc).  These products find application in aluminum gears, implants, boat parts, pumps, erosion resistant screen filters, corrosion resistant tubing  etc. The properties of the layer are:

  • Superior hardness
  • Resistant against wear and corrosion
  • Excellent adhesion to the metal
  • Low friction coefficient
  • Electrical insulation

The hardness of these layer formed by PEO is superior compared to other treatment methods.

The benefits are:

  • Longer service lifetime 
  • The wear resistance in combination with the low friction coefficient warrants no erosion (up to 10 times higher hardness compared to metals)
  • Cost effective, suitable for light weight cheap aluminum alloys
  • Applicable on complex 3D shaped materials
  • Available in different colors
