Definitions

the present invention relates to a process for the electrochemical polishing of surfaces of titanium or titanium-containing alloys. This method is particularly useful for alloys having a titanium content of at least about 50 mole percent, such as the nickel-titanium alloy nitinol.
an electrolyte is used which comprises methanesulfonic acid and one or more, optionally substituted alkanediphosphonic acids.
the present invention also relates to the use of such an electrolyte for electropolishing surfaces of titanium and / or titanium-containing alloys, such as nitinol.
Electrochemical polishing or electropolishing, as well as the glazing and deburring of metal surfaces is a technique commonly used in the art to treat the surfaces of metal workpieces and articles. Such a treatment serves to improve the surface quality, for example by removing burrs on edges and surfaces, by smoothing, cleaning and glazing, both for decorative and technical purposes. Furthermore, by the electropolishing stresses in the outer material layers can be removed.
the workpieces to be machined are arranged on suitable, electrically conductive holding devices, or in baskets or drums of electrically conductive material. These workpieces are immersed in a polishing bath containing an electrolyte and connected anodically, applying a direct current. As a result of the action of the current and of the electrolyte, metal is removed from the material surface, whereby the surface is smoothed and deburred. The workpiece is then removed from the polishing bath and rinsed off.
EP 1 354 986 A2 For example, there is described an apparatus and method for electropolishing titanium and titanium alloys (Titanium Grade 1 to 10) using an electrolyte of sulfuric acid and alcohols.
this method has the further disadvantage that due to the easy flammability of this electrolyte requires a complex cooling of the electrolyte to temperatures below 15 ° C. is, in conjunction with automatic extinguishing systems for fire protection.
the patent application DE 100 37 337 A1 describes a method and fixture for electropolishing bodies of titanium alloys or nickel-titanium alloys such as Nitinol, wherein the electrolyte comprises formamide and sulfamic acid.
the present invention is an electropolishing process for the electrochemical smoothing and / or deburring of surfaces of titanium or titanium-containing alloys, which does not have the aforementioned disadvantages. These methods are based on the use of an electrolyte comprising methanesulfonic acid and one or more alkanediphosphonic acids, wherein the one or more alkanediphosphonic acids may optionally be substituted with one or more hydroxy and / or amino groups.
the concentration of methanesulfonic acid in the electrolyte is at least 95% by weight, based on the total weight of the electrolyte.
concentrated methanesulfonic acid with a content of at least 98% by weight for example methanesulfonic acid with a content of more than 99% by weight, is used, to which the one or more alkanediphosphonic acids are added as pure substance (s).
a particularly suitable alkane diphosphonic acid for use in the processes described herein is 1-hydroxyethane-1,1-diphosphonic acid (HEDP, also referred to as etidronic acid).
HEDP 1-hydroxyethane-1,1-diphosphonic acid
electrolyte used in the process described herein HEDP may be used alone or in combination with other alkane diphosphonic acids in concentrated methanesulfonic acid as previously defined.
the concentration of the one or more alkanediphosphonic acids in the electrolyte is preferably between 1 and 50 g / kg of electrolyte, for example between 3 and 25 g / kg of electrolyte.
the one or more alkane diphosphonic acids be used between 5 and 20 g / kg of electrolyte.
the electrolyte consists essentially of methanesulfonic acid and one or more alkane diphosphonic acids This means that no other substances are added and such other substances only in small amounts, for example less than 3 wt .-%, are present, such as by impurities of methanesulfonic acid or alkanediphosphonic, or due to the operation in the course of electropolishing (for example ablated ions).
the electrolyte used in accordance with the present process contains no or only minor amounts of water.
the water content of the electrolyte is therefore preferably at most 2 wt .-%, more preferably below 1 wt .-%, based on the total weight of the electrolyte.
the electropolishing is preferably carried out at a temperature in the range of 20 ° C to 70 ° C, for example between room temperature and 60 ° C, and in particular at a temperature between 25 ° C and 50 ° C.
the anodic current density at which the workpieces are electropolished can be chosen from a wide range. This is preferably in the range from 2 to 50 A / dm 2 , in particular between 5 and 30 A / dm 2 .
the applied voltage can often be in the range of 10 to 35 volts.
the duration of the electropolishing process of course depends on the particular roughness of the workpiece to be machined and the desired smoothing or deburring.
the optimum exposure time can be determined by the average person skilled in the art within the scope of routine experiments as a function of the current density used, the temperature, the electrolyte and the device used without any particular effort. As a rule, a treatment of the workpiece is sufficient for a few minutes.
the machined workpiece is removed from the electropolishing bath and rinsed with water, preferably deionized water. It is not crucial that the workpiece is immediately freed from the electrolyte.
the electrolyte described here does not attack the machined surface, which facilitates the processing and makes no further demands on the equipment used.
This electrolyte described here can be used both for pure titanium and for titanium-containing alloys.
These titanium-containing alloys may in particular comprise titanium in a proportion of at least 50 mol%.
An important such alloy comprising titanium at a level of about 50 mole percent is the nickel-titanium alloy nitinol, also referred to as a "memory alloy".
nitinol also referred to as a "memory alloy
an electrolyte comprising methanesulfonic acid and one or more alkanediphosphonic acids to electropolish surfaces of titanium, titanium-containing alloys, and nickel-titanium alloys, such as nitinol, is also an aspect of the invention described herein.
electrolytes require in their use - in contrast to the electrolytes used in the prior art - no technically complex facilities, but can in conventional industrial electropolishing, as used for example for the treatment of stainless steel, are used.
an electrolyte as used in accordance with the present invention is nonflammable, not very corrosive, and easy to handle. With normal handling, there is no increased risk for the people who operate the electropolishing system or work in the vicinity of this system, as well as for the environment. In particular, the electrolyte described herein releases no harmful gases or vapors.
the methods and electrolytes described herein are not only easier to handle in the treatment of titanium-containing surfaces, but also make it possible to achieve a smoothening or de-burring of the surfaces as described in the prior art. at least equal, if not superior in many cases.
a sheet measuring 50 ⁇ 50 ⁇ 1.0 mm with a ground surface and a roughness of Ra 0.8 ⁇ m was used in an electrolyte consisting of 990 g of methanesulfonic acid 100% and 10 g of 1-hydroxyethyl-1,1-diphosphonic acid electropolished.
the sheet was degreased before treatment, rinsed with water and dried. After electropolishing, the sheet was removed from the electrolyte and rinsed in deionized water after a waiting time of 5 minutes and dried.
the edges were smooth and burr-free.
a 0.8 mm diameter nitinol wire was electropolished in an electrolyte according to Example 1.
the wire was pretreated and post-treated according to Example 1.
the result was a high gloss and smooth surface without etching attack on the microstructure.
