P. Hivart et Jp. Bricout, PREPARATION OF STEELS BEFORE PHOSPHATING - DEGREASING AND PICKLING - KEYS OF PHOSPHATATION SUCCESS, Revue de métallurgie, 93(1), 1996, pp. 139-149
Phosphating and soaping treatments of steel billets facilitate cold fo
rging operations. The success of these treatments depends on prior sur
face preparation (pickling preceded or not by degreasing). A tribologi
cal test is used to assess the effect of this preparation on the mecha
nical behaviour of phosphated and lubricated coatings. The role of the
degreasing step is shown, Mechanical and tribological properties of t
he phosphated part can be related to parameters of the pickling proces
s.
