4. Metals likely to be phosphated
Mechanical parts or sheet metal assemblies are, as a general rule, phosphated on finished products. The steels are therefore in their final metallurgical structure, obtained by the appropriate heat treatments, and in their machined finished state specific to their use; they may also have already undergone mechanical or mechanochemical surface preparation (tribofinishing).
Phosphating can be carried out on all structures where the steel's chemical composition permits (see table 6 ).
However, the surface must be free of amorphous or passive layers 5

Standardization
There are currently no AFNOR standards for phosphating. There are, however, a number of foreign standards, notably in Germany, Great Britain, Denmark, Italy, Japan, Sweden and the United States. Readers are referred to the works cited at
