Abstract
The utility model discloses a kind of wear-resistant multi-element coating, including：CrN layers, the CrAlSiN layers being located on the CrN layers, the ZrAlCuN layers being located on the CrAlSiN layers and the WS being located on the ZrAlCuN layers2Layer.This multi-element coating hardness height and good toughness, substantially increase the wear resistance of coated cutting tool, so as to improve the service life of cutter, cutting speed and machining accuracy, have good oxidation resistance, and its surface is WS2Soft coating, when coated cutting tool is cut, tool surface can form the continuous solid-state lubricating layer with lubricating action, also can reach without lubricating oil and reduce friction, prevent to bond, reduce cutting force and cutting temperature, the purpose for reducing tool wear.
Description
Technical field
It the utility model is related to coating for metal surfaces technical field, more particularly to a kind of wear-resistant multi-element coating.
Background technology
Modern metal cutting processing request cutter has the excellent spies such as high cutting speed, high rigidity, high-feed, high accuracy
Property.High-speed steel or hard alloy steel are increasingly difficult to meet the development need of modern mechanical processing industry as traditional cutter material
Will, therefore, tool surface coating technology is come into being.Tool surface coating technology is the material surface that recent decades grow up
Treatment technology, under appropriate technology condition, coating has good characteristic, coated in tool surface, can carry significantly
The service life of high metal cutting tool.When the development trend of Front-coating mirror is that coating tends to diversification and multiple stratification, laminated coating
The advantages of single coating can be integrated, the appearance of multilayer multicoat and its correlation technique make that coating can both improve and the combination of matrix is strong
Degree has the comprehensive performance of multiple material again, further improves the performance of cutter.
During tool sharpening, prolonged processing can cause to wear to cutter so that the service life reduction of cutter, and
And it can also influence the quality of workpiece.
Utility model content
The purpose of this utility model is to provide a kind of wear-resistant multi-element coating, is applied to tool surface, can slow down
The abrasion of cutter.
The technical solution of the utility model is as follows：A kind of wear-resistant multi-element coating, including：CrN layers, be located at it is CrN layers described
On CrAlSiN layers, the ZrAlCuN layers being located on the CrAlSiN layers and the WS being located on the ZrAlCuN layers2Layer.
Further, thickness CrN layers described is 0.2-0.4 microns, it increases CrAlSiN layers and knife as basic unit
Bond strength between tool, and Cr can also be formed during high temperature2O3, oxygen can be prevented persistently to be spread in coat inside, improve coating
Oxidation resistance.
Further, thickness CrAlSiN layers described is 0.3-0.6 microns, and Al element solid solutions therein are in CrN, both
Distortion of lattice can be produced, internal stress is produced, improves coating hardness, and Al caused by high temperature2O3Coating can not only be improved
High-temperature oxidation resistance, and the wear mechanism of coating can be changed, reduce the skin-friction coefficient of coating.
Further, thickness ZrAlCuN layers described is 0.8-1.2 microns, and ZrAlCuN layers have hardness height and toughness concurrently
The advantages of good, improve the ability of cutter resistance shock loading.
Further, one layer of outermost is WS2Layer, its thickness are 1.2-1.5 microns.WS2Layer is soft coating, when coating knife
When tool is cut, tool surface can form the continuous solid-state lubricating layer with lubricating action, also can reach and subtract without lubricating oil
Small friction, prevent to bond, reduce cutting force and cutting temperature, the purpose for reducing tool wear.
Using the above scheme, the utility model compared with the existing technology, has the following advantages that：
1st, this multi-element coating hardness height and good toughness, substantially increase the wear resistance of coated cutting tool, so as to improve
Service life, cutting speed and the machining accuracy of cutter；
2nd, this multi-element coating has good oxidation resistance；
3rd, this multi-element coating surface is WS2Soft coating, has relatively low friction coefficient.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of wear-resistant multi-element coating, including：CrN layers 10, be located at it is CrN layers described
CrAlSiN layers 20 on 10, the ZrAlCuN layers 30 being located on the CrAlSiN layers 20 and it is located on the ZrAlCuN layers 30
WS2Layer 40.
The thickness of the CrN layers 10 is 0.2-0.4 microns, it is increased between CrAlSiN layer 20 and cutter as basic unit
Bond strength, and Cr can also be formed during high temperature2O3, oxygen can be prevented persistently to be spread in coat inside, improve the anti-oxidant of coating
Ability.The thickness of the CrAlSiN layers 20 is 0.3-0.6 microns, and Al element solid solutions therein can produce lattice in CrN
Distortion, produces internal stress, improves coating hardness, and Al caused by high temperature2O3The high-temperature oxidation resistant of coating can not only be improved
Property, and the wear mechanism of coating can be changed, reduce the skin-friction coefficient of coating.The thickness of the ZrAlCuN layers 30 is
0.8-1.2 microns, the advantages of ZrAlCuN layers 30 have hardness high and good toughness concurrently, improve the energy of cutter resistance shock loading
Power.One layer of outermost is WS2Layer 40, its thickness are 1.2-1.5 microns.WS2Layer 40 is soft coating, when coated cutting tool is cut
When, tool surface can form the continuous solid-state lubricating layer with lubricating action, and reduction friction is also can reach without lubricating oil, is prevented
Bond, reduce cutting force and cutting temperature, the purpose for reducing tool wear.
In conclusion the utility model compared with the existing technology, has the following advantages that：
1st, this multi-element coating hardness height and good toughness, substantially increase the wear resistance of coated cutting tool, so as to improve
Service life, cutting speed and the machining accuracy of cutter；
2nd, this multi-element coating has good oxidation resistance；
3rd, this multi-element coating surface is WS2Soft coating, has relatively low friction coefficient.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the present invention, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
