Anodization – Sulphuric Acid

Anodization – Sulphuric Acid

The sulphuric acid anodizing process is a process without chromic acid which is used particularly in the aviation industry. This process, which is very environmentally compatible, is used for coating aluminum parts in order to achieve outstanding corrosion resistance.

Base Materials: Aluminium

Main characteristics

  • high corrosion resistance
  • high wear resistence
  • electrically insulating
  • consistent between ph 5 and ph 8
  • environmentally compatible

Layer thicknesses from 5 to 30 µm (depending on anodizing process)

Full range of electro-colors(Dyeing), which cover for all the current market trends while allowing for integration of future new colorings and shades which can be developed according to and in collaboration with client needs.

Pickling & Passivation

Pickling & Passivation

Pickling

A term used to describe the etching or dissolution of the stainless steel surface (a controlled dissolving of the surface). A relatively small loss from the surface is witnessed in the order of µm values typically 5 – 10 µm are removed from the surface thus rendering the “new” surface a virgin surface and free from contamination from fabrication, manufacturing or product from processing.

Passivation

“Artificial” re-building of the passive layer or passive film that renders the surface of stainless steel passive or corrosion resistant (it is the low level of electrical conductivity across this film that helps maintain corrosion resistance).
