What applications with DALIC?There are a wide range of applications approved by various manufacturers in the aerospace sector: Planes, missiles, launcher bodies, wings, engines, landing gears, etc.

• Corrosion protection on steel with: Cadmium, Zinc-Nickel, Tin-Indium, etc...
• Corrosion protection on aluminum with: Anodic oxydizing.
• Anti-Fretting with: Highly ductile Nickel or binary or ternary alloys like Nickel-Tin-Lead.
• Repair of scratches or corrosion pittings with: Silver, Copper or Nickel.
• Use of Cadmium with the non-drip Dalistick

The use of cadmium is now reserved to products and components linked to areas of high security or potential risk, or industries where human safety is a risk and priory. For that reason it is widely used in the aeronautic industry.

Cadmium's principal function is to protect steels from corrosion. In addition to its sacrificial properties in relation to steels (in most environments), we can add a good intrinsic resistance in corrosive environments, particularly with chlorides.

Cadmium also has a range of other interesting properties:

• Its products of corrosion are not very voluminous.
• It has a low coefficient of friction.
• Its potential is close to that or aluminum, so it is the selected coating for steels in contact with aluminum.
• We can easily solder it and it is compatible with most types of soldering.

A passivating treatment (chromatation) is generally done after the deposit to reinforce its resistance to corrosion.
