Abstract
The invention discloses a cutter with soft and hard composite coatings. The matrix material is high-speed steel or cemented carbide. The surface of the matrix is provided with the coatings. The coatings comprise a soft coating and a hard coating. The MoS2 soft coating is on the surface of the matrix, and on the surface of the soft coating is the high hard film hard coating. With the integration of advantages of the MoS2 soft coating and the high hard film hard coating through the above mode, the cutter with the soft and hard composite coatings has both high hardness and high friction coefficient, and the performance of the cutter is greatly raised. As the high hard film hard coating has very excellent wear resistance, the service life of the cutter can be prolonged, and the cost is reduced.
Description
Technical field
The present invention relates to the cutter field, particularly relate to a kind of soft and rigid composite coating layer.
Background technology
According to the character of coating material, coated cutting tool can be divided into two big types again, that is: " firmly " coated cutting tool and " soft " coated cutting tool.The main target that " firmly " coated cutting tool is pursued is high hardness and wearability, and its major advantage is that hardness is high, anti-wear performance is good.The target that " soft " coated cutting tool is pursued is a low-friction coefficient, is also referred to as self-lubricating knife tool.The development trend of current cutter coat is: coating composition is tending towards diversification and compoundization.Composite coating can comprehensive single coating advantage, the appearance of compound overbrushing layer and correlation technique thereof makes coating not only can improve with high base strength but also have the combination property of multiple material, makes the performance of coated cutting tool that large increase arranged.In the prior art, the cutter that possesses high rigidity, high-wearing feature, low-friction coefficient simultaneously is actually rare, and ubiquity cost problem of higher.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of MoS of combining
2The advantage of soft coating and Gao Nai ganoine thin film hard conating had both had higher hardness, had high friction coefficient again, and cost is lower, the soft and rigid composite coating layer of long service life.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of soft and rigid composite coating layer is provided, comprises the matrix of high-speed steel or Hardmetal materials, said matrix surface is provided with coating; Said coating comprises soft coating and hard conating, and matrix surface is MoS
2Soft coating, the soft coating surface is the high hard conating of anti-the ganoine thin film.
In preferred embodiment of the present invention, be provided with the Ti transition zone between said soft coating, the hard conating.
In preferred embodiment of the present invention, said coating layer thickness is 1.0-4.0 μ m.
In preferred embodiment of the present invention, the anti-ganoine thin film of said height comprises superficial layer that is made up of the Al nitride and the basalis that is made up of the Cr nitride.
In preferred embodiment of the present invention, said soft coating thickness is 0.2-1.8 μ m, and said hard conating thickness is 0.2-1.8 μ m.
The invention has the beneficial effects as follows: soft and rigid composite coating layer of the present invention combines MoS
2The advantage of soft coating and Gao Nai ganoine thin film hard conating had both had higher hardness, had high friction coefficient again; The performance of cutter is enhanced; The high hard conating of anti-the ganoine thin film has very excellent abrasive, can prolong the service life of cutter, has reduced cost.
Description of drawings
Fig. 1 is the perspective view of soft and rigid composite coating layer one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, matrix, 2, soft coating, 3, hard conating, 4, transition zone.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of soft and rigid composite coating layer comprises the matrix 1 of high-speed steel or Hardmetal materials, and said matrix 1 surface is provided with coating, and said coating comprises soft coating 2 and hard conating 3, and matrix 1 surface is MoS
2Soft coating 2, soft coating 2 surfaces are the high hard conating of anti-ganoine thin film the 3.
Wherein, said coating layer thickness is 1.0-4.0 μ m; The anti-ganoine thin film of said height comprises superficial layer that is made up of the Al nitride and the basalis that is made up of the Cr nitride; Said soft coating 2 thickness are 0.2-1.8 μ m, and said hard conating 3 thickness are 0.2-1.8 μ m.
Be provided with Ti transition zone 4 between said soft coating 2, the matrix 1, Ti transition zone 4 can reduce residual stress, increases the bond strength between coating and cutter.
Soft and rigid composite coating layer of the present invention combines MoS
2The advantage of soft coating 2 and Gao Nai ganoine thin film hard conating 3 had both had higher hardness, had high friction coefficient again; The performance of cutter is enhanced; The high hard conating of anti-the ganoine thin film has very excellent abrasive, can prolong the service life of cutter, has reduced cost.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
