Cobalt Leaching

  • Tungsten carbide grains embedded in a cobalt matrix
  • Cobalt easily oxidized in aqueous solution
  • Cobalt binder leaching impacts substrate cohesion

We have been developing a dedicated product line to avoid Cobalt leaching during the acqueous cleaning process: VACUKLEEN which contains cobalt leatching inhibitors.

Benefits
  • Excellent cleanliness of the Tungsten carbide and HSS
  • Remove all kinds of pollution (oil, grease, grinding & polishing compounds…)
  • Prevent from Cobalt Leaching and Corrosion
  • Extend life time of the parts
  • Gives a bright & shinny aspect to the surface
  • Safe & Environment friendly
removing grinding compound and oils from tools

Removing grinding compounds and oils from cutting tools (H.S.S hard metal)

Without cobalt leaching, prior to vacuum metallisation (P.V.D)
