Description
Technical field
The invention belongs to material surface modifying technology fields, and in particular to a kind of multi-layer composite coatings, knife for cutter
Tool and preparation method thereof.
Background technology
CrAlN coatings are widely used in cutter, mold as protection materials.CrAlN substitutes the Cr in CrN by Al and is formed
Cubic structure metastable phase CrAlN coatings, crystal structure and mechanical property can change with the variation of Al content.It is keeping
When the face-centred cubic structure of CrN, and the mechanical property of coating can rise with the rising of Al content, when Al content is more than consolidating for CrN
When solubility, the structure of coating converts to the AlN of hexagonal structure and its mechanics and hot property is made to be remarkably decreased.
CrAlN coatings are often applied to high temperature applicationss as protection materials, and therefore, high-temperature behavior is extremely important.
The high-temperature oxidation resistance of CrAlN coatings is preferable, is higher than 1000 DEG C.But the CrAlN coatings of metastable phase are in high temperature (being higher than 900 DEG C)
Shi Huixiang its stable phase Cr and the AlN of close-packed hexagonal conversion and make its mechanical properties decrease, wherein the generation of Cr need by
Cr2N transition complete, the unstable release N atoms of Cr-N keys especially in coating thermal decomposition process and keep its mechanical property notable
It reduces.
Multi-element alloyed and multilayered structure optimization based on CrAlN coatings is the effective means for improving its performance at present.
Zr is added in CrAlN coatings, since the bond energy between Zr-N is higher than Cr-N keys and Al-N keys, CrAlN coatings can be significantly improved
Thermal stability.After adding Zr, in Cr0.48Al0.52The initial temperature of N coatings thermal decomposition increases, and the hardness of coating also rises therewith
It is high.But the addition of Zr can reduce the solid solubility of A1 in CrAlN coatings, and excessively high Zr additions can be such that the structure of coating turns to hexagonal phase
Change and its performance is made to decline.
Another means multilayered structure that coating material is modified can combine the advantage of different materials, especially when MULTILAYER COMPOSITE applies
For each layer of thickness control of layer in nanoscale, a kind of material can be that template coherent strengthening (be also known as using another material
Position superstructure coating), interface enhancing effect can be such that the hardness of coating steeply rises.The state of interface of multi-layer composite coatings removes
It is closely related outer with its modulation period and modulation ratio, also (for example by each coating material intrinsic performance：Lattice constant, mould
Amount etc.) influence.Due to Cr0.32A0.68The lattice constant difference of two kinds of materials of N and ZrN is too big (~12%), leads to its strain energy
Superstructure coating that is too big and being hardly formed complete coherent growth.When the modulation period of CrAlN/ZrN coatings is 9nm, CrAlN
Layer and the ZrN layers of multi-layer composite coatings for complete non-coherence, at this time ZrN layers of introducing do not have the performance of CrAlN coatings substantially
It influences.5nm is reduced to when the modulation period of CrAlN/ZrN coatings, the interface between CrAlN layers and ZrN layers is part coherence circle
Face, at this point, the hardness of coating and thermal stable temperature have promotion.
Invention content
In order to solve the above technical problems, the multi-layer composite coatings that the purpose of the present invention is to provide a kind of on cutter,

It is low, it is difficult to control in industrialized production；Thickness in monolayer is too high, and accumulative strain energy is excessive during each monolayer growth, it is difficult to
The laminated coating of coherent strengthening is obtained, in the thickness range, the multilayer that can obtain coherent strengthening applies each single layer
Layer.
Preferably, the overall thickness of the multi-layer composite coatings is 1 μm~12.0 μm.
Preferably, the overall thickness of the multi-layer composite coatings is 1 μm~6.0 μm, and preferably 3 μm, multi-layer composite coatings are such as
Fruit is excessively thin, influences whether the protective value and protecting effect of composite coating, but blocked up composite coating not only will produce it is excessively high
Stress causes coating easily to peel off, and cost is consequently increased, the coating in the thickness range have preferably protective value,
Protecting effect is not easy to peel off, at low cost.
Preferably, it is additionally provided with Cr between described matrix and the multi-layer composite coatings1-xAlxN transition zones, Cr1-xAlxN transition
The introducing of layer can improve the bond strength between coating and matrix.
