Definitions
- the invention relates to a hard-coated body with a plurality of CVD applied hard material layers.
- the cutting material should in particular be resistant to abrasion, which already led early to hard metal or cermet substrate bodies having been provided with surface coatings, wherein first carbides, nitrides or carbonitrides of titanium and later also aluminum oxide layers have been used as wear protection layers.
- first carbides, nitrides or carbonitrides of titanium and later also aluminum oxide layers have been used as wear protection layers.
- multi-layer wear protection layers of different hard materials are also known.
- wear-reducing layers for example, aluminum oxide layers are known, which are arranged on one or more intermediate layers such as titanium carbonitride or titanium nitride.
- WO 03/085152 A2 discloses the use of a Ti-Al-N layer which can be produced as a monophase layer with aluminum contents of up to 60% by means of PVD. At higher aluminum contents, however, a mixture of cubic and hexagonal TiAIN is formed, and with even higher proportions of aluminum only the softer and not wear-resistant hexagonal wurtzite structure is produced.
- WO 2007/003648 A1 in order to improve the wear resistance and the oxidation resistance, it is proposed to produce a hard-coated body with a single- or multilayer coating system by means of CVD, which contains at least one Tii- X Al x N-hard material layer, to which the body in a reactor is coated at temperatures in the range of 700 ° C to 900 0 C by CVD without plasma excitation and should be used as precursors titanium hallogenides, aluminum halides and reactive nitrogen compounds, which are mixed at elevated temperature.
- the chlorine content is in the range between 0.05 to 0.9 at%.
- the Tii- X Al X N hard-material layer or layers can contain up to 30% by mass of amorphous layer constituents.
- the hardness value of the layers obtained is in the range of 2,500 HV to 3,800 HV.
- the layer system applied to a substrate body consists of a titanium nitride, titanium carbonitride or titanium carbide bonding layer applied to the body followed by a phase gradient layer followed and finally an outer layer of a single- or multi-phase Tii -x Al ⁇ N hard material layer.
- the phase gradient layer consists of a TiN / h-AlN phase mixture on its side facing the connection layer and, with increasing layer thickness, has an increasing phase fraction of fcc-TiAIN with a proportion of more than 50% and, concomitantly, a simultaneous decrease in the phase proportions of TiN and h- AIN on.
- the thermal resistance of the coating is of great importance for the application of this material during machining operations, in particular at high cutting speeds.
- temperatures that are significantly above 1000 ° C. are produced.
- different coefficients of expansion that exist for the substrates between the individual layers, significantly. This leads to the formation of stresses between the individual layers and, if the high temperature is transported by heat conduction from the outer layer to the substrate body, in the worst case to a detachment of the coating, making the cutting insert is unusable.
- T ⁇ i -X Al X N, Tii- X Al X C or Ti 1-X Al X CN layer instead of a commonly used in the prior art TiCN layer has the advantage that the thermal conductivity in the below
- the Al 2 O 3 layer arranged layer is about 80% lower, so that the T ⁇ 1-X AI X N, Tii -X AI X C or CN layer proves to significantly improve thermal insulation to the substrate body.
- the outer AbOa layer is also more resistant to oxidation and harder by about 50% compared to a TiCN outer layer, resulting in a higher wear resistance.
- the Ti- X Al X CN, Tii -x Al ⁇ C or Tii- X Al X N layer may be single-phase and have a cubic structure or be multi-phase and have a further phase in wurtzite structure and / or TiN in addition to a main cubic phase , Up to 30 mass% may contain amorphous layer constituents.
- the chlorine content is between 0.01 to 3 At%.
- a TiN and / or TiCN layer can be used as a bonding layer to the substrate body, which consists of a hard metal, a cermet or a ceramic, so that the sequence of layers from the inside to the outside TiN or TiCN TiAIC (N) -Al 2 O 3 is.
- TiCN layers are also possible between the Al 2 O 3 outer layer and the Tii- X Al x N layer, Ti 1-x Al x C layer or the Tii- x Al x CN layer.
- the aluminum content as metal content is preferably between 70% and 90%.
- the layer thickness of a Ti 1-X Al x N layer, Tii -X AI x C layer or a Ti 1-X AI x CN layer may vary between 2 .mu.m to 10 .mu.m, preferably 3 .mu.m to 7 .mu.m.
- the aforementioned layer may also contain proportions of hexagonal aluminum nitride, at most 25%.
- the TiAIN / TiAICN / TiAIC alternating layer then has a total thickness resulting from the sum of the thicknesses of each individual layer, which is between 1 nm to 5 nm.
- the total thickness should be at least 1 micron to 5 microns.
- the TiAIN, TiAIC or TiAICN layer can contain up to 30% amorphous and chlorine levels up to 3 at%.
- a cermet or a ceramic substrate body is subjected to a CVD coating at coating temperatures between 650 0 C and 900 0 C, wherein in the gas atmosphere titanium and aluminum chlorides and ammonia are introduced to produce a TiAIN layer.
- a first between 2 .mu.m and 10 .mu.m, preferably 3 .mu.m to 7 .mu.m thick layer is applied in a conventional manner by means of the CVD method at least 2 microns maximum 10 microns thick Al 2 ⁇ 3 layer.
