Definitions

  • the invention relates to novel powder mixtures, in particular cermet powder, for the surface coating of metal substrates by thermal spraying methods, such as plasma spraying or high-velocity flame spraying (HVOF), flame spraying, arc spraying, laser spraying or build-up welding, such as the PTA process.
  • thermal spraying methods such as plasma spraying or high-velocity flame spraying (HVOF), flame spraying, arc spraying, laser spraying or build-up welding, such as the PTA process.
  • Such powders consist of at least one finely divided hard material powder such as WC, Cr 3 C 2 , TiC, B 4 C, TiCN, Mo 2 C, etc., as well as a finely divided metal or alloy matrix powder.
  • Hard powder and matrix powder are intensively - usually mixed in the presence of a solution of an organic binder, optionally with co-grinding -, atomized, dried, sieved and then heated to remove the organic binder and generating a sintered bond under a hydrogen-containing atmosphere, so that larger agglomerates of 10 bis 100 ⁇ m particle diameter arise.
  • a flame spray powder which contains as carbide metal carbides and as metal 10 to 45% aluminum and nickel.
  • Cobalt- and nickel-containing powders have found their way into the art as matrix metal powders.
  • GB 2,214,523 describes a material consisting of 60 to 90 vol.% Cr 3 C 2 and 40 to 10 vol.% of an alloy selected from the group consisting of Co-28-32%, Cr-9-11% Ni-3.5-5.5% W and Fe-28-31% Cr-4.5-5.5% Al-0.4-0.6% Y and mixtures thereof, the% data being on Refer to weight percent.
  • JP 2005-320557 describes an abrasion resistant member consisting of a base metal and a cured coating, the cured coating 60-20 wt.% Of an Fe-Cr-C based alloy matrix and 40-80 wt.% Of hard metal particles having an average particle diameter of D50 of 60-800 ⁇ m dispersed in the matrix.
  • the object of the invention is, on the one hand, to further reduce the use of cobalt, since cobalt, because of its widespread use, has become a scarce raw material.
  • a further object of the invention is to provide cobalt-poor cermet coatings which have comparable or increased abrasion and cavitation resistance over conventional Co-Cr matrix alloys.
  • the object of the invention is also to increase the corrosion resistance of cermet coatings, in particular to reduce the solubility of matrix metals from the coatings.
  • Preferred cermet powders according to the invention comprise the matrix metals nickel and cobalt in a weight ratio of at least 2: 3, more preferably in a weight ratio of 1: 1, particularly preferably in a weight ratio of 3: 2.
  • Particularly preferred cermet powders according to the invention are cobalt-free. More preferred cermet powders are cobalt and nickel free.
  • the ratio of the sum of the contents of chromium and aluminum to the sum of the contents of iron, nickel and chromium in parts by weight is preferably 1: 2.2 to 1: 3.7, more preferably 1: 2, 7 to 1: 3.6.
  • the matrix powders can be prepared in a manner known per se by atomizing metal or alloy or partial alloy melts.
  • the alloy is applied during application (for example, by spray coating) of the cermet powders.
  • Preferred cobalt, nickel and / or iron partial alloy matrix powders are prepared by chemical precipitation by reaction of corresponding salts with excess oxalic acid, drying and thermal treatment according to DE 198 22 663 A1 respectively.
  • US 6,554,885 B1 won, with chromium is added as metal powder.
  • Particularly suitable modifiers are steel substrate refining elements such as Mo, Nb, Si, W, Ta and / or V.
  • the matrix metal or matrix alloy powders are free of further constituents.
  • the present invention also relates to a cermet having the above-described composition and a molded article coated with such a cermet.
  • the one or more hard material powders and the one or more matrix powders and modifying agents with optionally different average particle sizes are slurried in an aqueous solution of an organic binder in a manner known per se, and by means of Homogenized mixed grinding in a ball mill, an attritor or a stirrer, and the suspension is sprayed in a spray dryer, wherein the water evaporates from the spray droplets.
  • the resulting powder agglomerate is converted into a nominal grain by means of a classification process (screening, screening) and the organic binder of the agglomerate is converted by sintering at a temperature of up to about 1300 ° C., in particular 1100 ° C. to 1300 ° C., in a hydrogen-containing atmosphere.
  • the resulting sinter cake is returned to the nominal grain band by conditioning (breaking, milling, sieving).
  • a tungsten carbide powder having a particle size of 0.9 ⁇ m determined by FSSS, having a carbon content of 6.1% by weight and a free carbon content of 0.05% by weight was used.
