Definitions

  • the present invention relates to a coating solution to be applied onto the surface of metals or metal alloys, a process for cold forming of metals and metal alloys using said coating solution, and a coated blank made of a metal or a metal alloy.
  • a protective film must be formed between the tool and the work piece, which must remain intact during the working process.
  • a protective film is mainly made up of molybdenum disulfide dispersions or graphite as lubricants.
  • lubricant carriers are applied onto the surface of the workpiece, which can absorb about five times the quantity of lubricants compared to the untreated metal surface.
  • the application of such lubricant carriers onto the surface of workpieces is carried out by applying aggressive acids and metallic soaps in huge amounts, which is not desirable from an ecological standpoint.
  • US-patent 6,309,477 describes pretreatment chemicals for metal materials to be painted containing at least one kind of sulfur-containing compounds and at least one of phosphorus ion-containing compounds, and an anticorrosive treatment of metal materials.
  • JP-A-2001-303262 describes a plated steel sheet covered with an organic film for high corrosion resistance.
  • EP-A-0 613 939 describes a graphite-free lubricating oil which comprises a base oil having dispersed therein a carbohydrate and/or a derivative thereof, a film-boosting agent and a dispersant.
  • the technical problem underlying the present invention is to provide a new system for cold forming of metals and metal alloys, which should avoid the treatment of the working piece with aggressive acids and/or metallic soaps prior to the cold forming process, but should exhibit at least the same results compared to a cold forming process using workpieces treated with aggressive acids and/or metallic soaps.
  • a coating solution to be applied onto the surface of a metal or a metal alloy comprising 2 to 8% (w/v) of a polyphosphate, 2 to 5 % (w/v) of a dithiocarbamate, 5 to 12% (w/v) of graphite and 5 to 12 % (w/v) of molybdenum disulfide.
  • the polyphosphate is selected from the group consisting of ammonium polyphosphate and alkali metal polyphosphates, such as sodium polyphosphate, or mixtures thereof.
  • the dithiocarbamate is preferably a dialkyl dithiocarbamate, wherein the alkyl groups are the same or different and can have 1 to 12 carbon atoms.
  • the dithiocarbamate is a heavy metal dithiocarbamate, wherein the heavy metal is for example molybdenum.
  • the dithiocarbamate is a molybdenum dibutyldithiocarbamate.
  • the coating solution may further contain at least one component selected from the group consisting of alcohols in an amount of from 0 % to about 100% (v/v); waxes such as polyalkylene waxes, e.g. polyethylene waxes, microcrystalline waxes, and Montan ester waxes, in an amount of from 0 % to about 80 (v/v); emulsifying agents such as alkyloxyethylates and alkylaryloxyethylates, in an amount of from 0 % to about 50% (v/v); pH-modulating agents such as buffers, e.g.
  • phosphorous acid and esters thereof in an amount of from 0 % to about 50% (v/v); polymeric compounds such as polyethylene glycols, preferably having a weight average molecular weight of from 500 to 1,000,000, polysaccharides and methylcellulose, in an amount of from 0% to about 50% (v/v); oxides such as silicon dioxide, in an amount of from 0% to about 50% (v/v); friction-reducing agents such as sodium stearate, in an amount of from 0% to about 80% (v/v); defoaming agents such as fatty alcohol polyglycol ethers, in an amount of from 0% to about 50% (v/v); carboxylic acids and derivatives thereof such as 2-phosphonobutanetricarboxylic acid, in an amount of from 0% to about 50% (v/v); organophosphorous compounds such as alkylphosphates, in an amount of from 0% to about 5% (v/v); and phosphates such as boron phosphate, sodium phosphate, P 2 O
  • the coating solution has a pH-value ranging from about 3 to about 4, adjusted by the above-defined pH-modulating agent.
  • the solvent used for the coating solution of the present invention is H 2 O in an amount of from 0% to 100% (v/v), alcohols, preferably alcohols having up to 10 carbon atoms such as methanol, ethanol, etc., or a mixture of different alcohols, in an amount of from 0% to 100% (v/v), or a H 2 O/alcohol-mixture in an amount of from 0% to 100% (v/v).
  • the present invention relates to a process for cold forming of metals or metal alloys, comprising the steps of:
  • the blank can be sand-blasted prior to the above process step (a).
  • a blank made of a metal or a metal alloy such as steel having a coating obtainable by the above-defined process steps (a) and (b).
  • the coating solution of the present invention does not exhibit the severe drawbacks with respect to environmental pollution, and on the other hand the blanks having a coating based on the coating solution of the present invention show at least the same results for the processed workpiece and the tool when compared with blanks having a coating known in the prior art.
  • the cold forming process using blanks treated with the coating solution of the present invention is superior from an economical standpoint, i.e. the weight of the coating on the blank is much less as compared to the weight of a coating known in the art.
  • 25 cylindrically shaped steel blanks (examples 1 to 25) having a length of 500 mm are immersed in a coating solution containing 2-8 % (w/v) polyphosphate, 2-5 % (w/v) dithiocarbamate, 5-12 % (w/v) graphite and 5-12 % (w/v) molybdenum disulfid for a time period of about 1 min. Then, the blanks having the coating solution on their surfaces are transferred to a drying stove wherein they are dried at a temperature of about 60°C for about 30 min. For comparison, 5 cylindrically shaped steel blanks (Comp. Examples 1 to 5) having a length of 500 mm are coated using the agents and procedure known in the art.
