Definitions
- the invention relates to a process for producing a coating on at least 5 parts of the surface in the region of the cutting edge (s) of a cutting tool.
- the invention relates to a cutting tool with a hard material layer applied to at least 10 parts of the surface in the region of the cutting edge (s).
- the invention is also directed to the use of a cutting tool with a coating.
- Cutting tools made of high-speed steel, high-chrome alloy tool steel or hard metal, which have a surface coating made of a compound, in particular a titanium compound, for example titanium nitride, in the area of the cutting edge (s)
- Hard material coatings with compounds from other elements of groups 4, 5 and 6 of the periodic table for example vanadium nitride, zirconium nitride, chromium nitride, niobium nitride and the like, are known in the art. Also were out
- PVD physical -
- All known layer materials have a higher hardness than at least the matrix of the tool body or the substrate and can therefore increase the abrasion resistance of the surfaces at the cutting edge or the service life of the cutting edge itself of the tool. Higher layer hardness often result to an advantageous change in the wear behavior of the tool.
- the wear resistance of a coated tool or its service life depends essentially on the mechanical stability of the coating and the chemical properties of the hard material layer.
- the roughness of the substrate should have a maximum profile height R ⁇ depending on its material properties according to DIN 4762 of at most less than 25 ⁇ m, the smallest profile heights not significantly improving the adhesive strength, however may involve an increased production effort and the risk of plastic deformation of tips.
- large coating thicknesses of over 10 to 15 ⁇ m increase the tendency for detachment.
- the invention is based on the object of specifying a method for coating the surface in the cutting edge region of a cutting tool, which method provides increased adhesive strength on the basic tool body, increased corrosion resistance and reduced abrasion of the coating.
- Another object of the invention is to provide a cutting tool with a hard material coating, which tool has a significantly longer service life in high-stress operation.
- the invention is directed towards a particular usability of a cutting tool.
- Substrate sanded and a maximum profile height in the cross profile of the surface ⁇ R ⁇ of less than 8 ⁇ m is set, whereupon a profile smoothing to a profile depth Y v of 1 to 5 ⁇ m, preferably 1 to 3 ⁇ m, and a layer of nitride, carbide, carbonitride, optionally with oxygen components, on the substrate surface formed in this way
- a profile smoothing to a profile depth Y v of 1 to 5 ⁇ m, preferably 1 to 3 ⁇ m and a layer of nitride, carbide, carbonitride, optionally with oxygen components, on the substrate surface formed in this way
- Example oxicarbide of at least two elements of the
- Groups 4,5 and 6 of the periodic table with a thickness of 0.5 to 5 microns is applied.
- the advantages achieved by the invention consist essentially in the fact that special conditions are created for a high adhesive strength of the coating and that the new layer has increased hardness, reduced friction and increased chemical stability.
- the tool surface to be coated is sanded, it subsequently has a cross-sectional profile perpendicular to the grinding direction with sharp tips, regardless of the roughness depth or the maximum profile height, according to DIN
- a profile tip smoothing is provided which, on the one hand, at least partially eliminates the disadvantageously acting profile elevations, and on the other hand ensures roughness of the substrate, which promotes the adhesive strength of the coating, as shown in FIG. 2.
- Will be a maximum Profiltaltiefe according to DIN 4762 of R M 1 micron in 0 advantageously from 1 to 5 microns 5 is set to 3, so the adhesion strength is. Coating reinforced by eliminating the disadvantageous peak effects.
- Tungsten highly corrosion-resistant, which surprisingly also applies to the connections of these metals. According to the invention can now
- the voltage In the case of ion etching or sputtering, in particular the profile tips, the voltage must be greater than the sputtering threshold and is advantageously between 150 and 280 V. If metal ion etching is carried out in a favorable manner, the voltage should have a value between 800 and 1500 V.
- a coating with a connection of at least one element from groups 6 and 4 of the periodic table is carried out.
- the corrosion resistance is increased by the elements Cr, Mo and W of group 6 of the periodic table, on the other hand there is a particularly pronounced atomic lattice strain by the elements of group 4 of the periodic table in the connection.
- the further object of the invention is achieved in a cutting tool of the generic type in that the coating surface of the ⁇ the tool or the substrate in the transverse profile of the surface, based on the direction of grinding, has a profile dome smoothed shape with a profile depth of R m of 1 to 5 ⁇ m and the hard material layer made of nitride,
- Carbide, carbonitride, optionally with oxygen components, for example oxycarbide is formed by at least two elements from groups 4.5 and 5 of the periodic table with a thickness of 0.5 to 5.0 ⁇ m.
- a profile dome-smoothed shape of the processing surface or the substrate surface with a profile depth Y v in the transverse profile of 1 to 5 ⁇ m, advantageously of 1 to 3 ⁇ m, represents the advantage according to the invention that, on the one hand, a favorable anchoring is achieved with a high bond strength of the layer, on the other hand, there is a largely even, tip-free design of the upper outer surface part, which is also apparent from FIG. 2.
- Coated metal compound connections are ultimately based on the
- the hard material layer is formed with elements of groups 6 and 4 of the periodic table, an attack and / or cutting edge removal of the can be targeted by the respective proportion of the metals in the connection when processing materials which emit corrosive media Tool can be significantly reduced.
- Ratio of up to 40 atomic% titanium, preferably from 5 to 15 atomic% titanium, on a high-speed steel substrate has been found to be particularly favorable.
- the composition of the coating changes in the thickness direction or the respective proportion of the metallic elements in the connection and thus the property of the layer changes.
- An increase in the mechanical values of the layer can be achieved if the elements aluminum and / or silicon are embedded in the hard material layer.
- Coated cutting tools made of high-speed steel or high-alloy tool steel have, as has been shown, a particularly long service life even with large mechanical and thermal loads if, as can be provided according to the invention, the tool base body or the substrate is produced by powder metallurgy. Investigations have shown that the formation and the homogeneous distribution of the carbides in the matrix in such substrates advantageously influence or design the surface treatment and the roughness formation even with different processing directions.
- the use of cutting tools according to the invention with a coating consisting of a compound, preferably a nitride of the elements chromium and titanium, has proven itself, with a particularly high profile of properties a proportion of about 12 atomic percent titanium in the metal component of the compound was reached.
- the coating had high chemical stability and a hardness comparable to that of pure titanium nitride. Also the adherence of polymerized organic compounds to the coating was minimized.
- the invention is to be further illustrated in the relevant investigations.
- Chromium nitride values from 1700 to 2000 HV and for pure titanium nitride values from approx.
- chromium nitride had good corrosion resistance, which was further improved by the presence of molybdenum and tungsten in the connection.
- proportions of titanium, zirconium, hafnium, niobium and vanadium increasingly reduced the resistance to corrosion from proportions of 10 to 40 atomic%, but increased the hardness of the connection or coating and occasionally had an embrittling effect.
- Chromium nitride also has a low coefficient of expansion compared to steel, for example high-speed steel, which reduces the stress in the
- Substrate is high. Titanium shares in the chrome nitride enlarge the
