Definitions

  • the present invention relates to processes for stripping hard material layers, except TiN, of cemented carbide substrates according to claims 1 and 2, respectively.
  • a hard material layer we mean a layer of an oxide, nitride, carbide, carbonitride or carbooxinitride of at least one element of groups 4, 5, 6, 13, 14 according to the "New Notation from IUPAC", for example according to " CRC Handbook of Chemistry and Physics, "CRC Press, 77th Edition," Periodic Table of Elements ", wherein the hard material layers of the aforementioned materials in H 2 O 2 containing solutions are poorly soluble . This hard materials TiN is excluded.
  • the thickness of the intermediate layer is substantially less than that of the functional hard material layer.
  • the intermediate layer thickness d z is, for example: 0 . 01 microns ⁇ d z ⁇ 0 . 5 microns . preferably 0 . 01 microns ⁇ d z ⁇ 0 . 3 microns . especially preferred 0 . 01 microns ⁇ d z ⁇ 0 . 2 microns ,
  • the hard material layer comprises a CrC-, CrN, CrCN or a WC-C layer.
  • the hard material layer comprises a TiAlN and / or TiCrN layer, wherein in a very particularly preferred Embodiment, the hard material layer comprises a TiAlN layer, more preferably, is a TiAlN layer.
  • the processes are preferably used on hard material layers having a layer thickness of at least 2 ⁇ m.
  • the solution used is preferably a hydrogen peroxide solution, preferably with at most 50% by weight of hydrogen peroxide, more preferably with at most 20% by weight of hydrogen peroxide.
  • this solution further preferably NaOH is added, this preferably with at most 5 wt.%, Particularly preferably with at most 0.5 wt.%.
  • the solution used except water, exclusively Wassenstoffperoxid, preferably with the stated wt.%, And NaOH, also preferably with the stated wt.%, And at least one of the mentioned substances di-sodium oxalate, K-Na Tartrate tetrahydrate, also preferably in the indicated concentration.
  • Carbide indexable inserts were coated with a layer package TiN / TiAlN.
  • the TiN intermediate layer had a thickness of 0.5 .mu.m, the total thickness of the package was 4 .mu.m.
