Definitions

  • the present invention relates to a composition of bath for the electrolytic polishing of a surface unalloyed titanium metal and a process of use of this bath.
  • polishing is meant a treatment to reduce the roughness of a metal surface and, hence, to increase the brightness with, as consequently, less sensitivity to corrosion.
  • the present invention is in the context electrolytic polishing technique.
  • Electropolishing is based on two simultaneous and antagonistic reactions, including relative and diffusion phenomena at the interface metal / solution control the operating process.
  • Moon of these reactions is a dissolution reaction during from which the metal goes into solution in form ionic; the other reaction is an oxidation reaction during which an oxide layer is formed more or less protection limiting the evolution of the first reaction.
  • These two reactions, antagonistic and complex compete with the consequence a self-limitation of the chemical attack of the surface metal, whose polishing is only a result particular.
  • the polishing obtained electrolytically is significantly influenced by viscosity and / or resistivity of the electrolyte used.
  • He is known to use various acid compositions, especially compositions based on hydrofluoric acids, sulfuric, nitric, phosphoric in concentrations variety. Some of these acids (eg acid hydrofluoric) allow the dissolution of the formed on the metal surface, while the others (eg phosphoric acid, sulfuric acid, etc.) form the viscous medium necessary for the evolution of the electrolytic polishing. Proper control of concentrations of the constituents of the electrolytes is necessary to ensure the proper evolution of the process and determine the lifespan of these electrolytes.
  • the present invention therefore essentially for purpose of proposing a bath composition for polishing electrolytic specificity of unalloyed titanium, so to obtain a metal surface having a degree of polishing of high quality and measurable, but also of way to obtain, by an appropriate choice of parameters implementation of the composition, metal surfaces with roughness predeterminable (“adjustable”) and measurable (eg for biocompatible titanium implants).
  • a so-called additive "cationic wetting agent" for example a quaternary salt ammonium such as cetyltrimethylammonium bromide or a substituted derivative such as hexadecylpyridinium bromide 0.1 to 0.5 g / l.
  • a quaternary salt ammonium such as cetyltrimethylammonium bromide or a substituted derivative such as hexadecylpyridinium bromide 0.1 to 0.5 g / l.
  • This agent modifies the polarization of one of two electrodes (alternating phenomena adsorption and desorption) in the medium and leads to modifications of double layer phenomena. It results in an improvement in the quality of polishing with less metal removal.
  • the means proposed by the invention it is possible to regulate and control with extreme precision the conditions of electrochemical dissolution of the titanium metal surface and we are also able to achieve a polishing degree of titanium well better than the techniques known to this day. So, to fix ideas, from a raw titanium rolling surface which has a maximum roughness Rt of the order of 1 to 2 ⁇ m and a average roughness Ra of the order of 0.1 to 0.15 ⁇ m, it is possible to obtain, after electrolytic polishing in the conditions of the invention, a maximum roughness Rt of the order of 0.5 ⁇ m and an average roughness Ra of the order of 0.05 to 0.10 ⁇ m with a dissolved thickness of metal of in the order of 50 to 100 ⁇ m.
