Definitions
- the alkaline solution contains phosphate ions and either cobalt or nickel ions or a mixture of [51] Int. Cl. ..C23g 1/16;C11d7/16;C23g1/20 th t U fth hl I t [58] Field of Search 252/146, 147, 387. 79.1, e be 0 e so u e p5 preen m m 5 age rusting and the problems resulting therefrom.
- Aqueous alkaline solutions based on soluble phosphates are often used for simultaneous removal (cleaning) of the lubricant carrier layers and the lubricant residues.
- Salts of orthophosphoric acid and/or salts of condensed phosphates come into consideration as phosphates.
- the treated workpieces are subject to considerable danger of rusting upon leaving the removal zone, and the rust occurs particularly in the transition zones between processing stages.
- the susceptibility to rust is also at least partially due to the deformation of the workpiece, and thus the change in the surface structure of the material.
- long carry-over times can sometimes intervene between the cleaning bath and the rinsing baths.
- the parts cleaned with the phosphate solution rust slightly during this time. However, this is undesirable and greatly interferes with subsequent treatments, especially for subsequent phosphation.
- the rust-inhibiting effect is attained upon the addition of at least 0.05 g/l of the metal compound, calculated as cobalt and/or nickel. Quantities of more than g/l offer no additional advantage. Preferably, 0.1 to 2 g/l of the metal or metals is added.
- Suitable cobalt salts include cobalt nitrate, cobalt sulfate, cobalt acetate, cobalt chloride.
- Suitable nickel compounds include nickel nitrate, nickel sulfate, nickel chloride, nickel acetate.
- the phosphates used in the cleaner in accordance with the invention primarily include those of condensed phosphoric acids, especially pyrophosphoric acid.
- the phosphate content advantageously amounts to 5 to 80 g/l, preferably to 50 g/l, calculated as P 0
- the aqueous cleaning solution normally has a pH of 8-13, and preferably the pH is kept in the range of 9-12.
- surface-active substances and/or solvents may be included.
- Suitable surfactants include anionic surfactants such as alkybenzencsulfonates, fatty alcohol sulfates, etc., or nonionic surfactants, such as ethylene oxide addition products to alkylphenols or fatty alcohols.
- nonionic surfactants When nonionic surfactants are used, it is necessary to make sure that these surfactants possess sufficient solubility at the concentration and temperature used.
- anionic surfactants are used. It is advantageous to add O.l3 g/l wetting agent.
- Organic solvents such as higherboiling hydrocarbons (kero- 2 sene, petroleum), glycols, or polyglycols are advantageously used in quantities of 0.510 g/l.
- the cleansing solution in accordance with the inven tion can advantageously be prepared from a solid cleanser concentrate.
- a concentrate preferably has the following composition:
- An alkaline phosphate-containing aqueous solution for the simultaneous cleaning degreasing and removal of a cold forming lubricant carrier layer from workpieces containing iron, comprising 5-80 g/l phosphate ion and at least 0.05 g/l of cobalt ion and having a pH adjusted to a value between 8 and 13.
