Abstract
The utility model discloses a kind of high speed cutting tool and manufacturing method based on PVD technique.It includes substrate, coated in substrate outside PVD coating, the surface etch of PVD coating has a rough irregular surface, and the periphery of PVD coating is coated with CVD coating, and PVD coating and CVD coating blends mutually as high-strength composite layer.The advantage is that: CVD coating and the binding force for the PVD coating for being etched with irregular surface are also stronger; to which thicker coating can also be deposited; PVD technique is utilized to protect the pretreatment of substrate, reduces influence of the higher temperature to substrate, substantially increases cutter material bending strength；CVD coating and the blending of PVD coating are improved into compound ability by lithographic technique and avoid coat inside in tensile stress state, cutter is set to generate micro-crack when in use, and PVD coat inside is in compressive stress state, internal micro-crack can be automatically repaired, and extend service life.
Description
Technical field
The present invention relates to a kind of high speed cutting tool, a kind of particularly high speed cutting tool and system based on PVD technique
Make method.
Background technique
Cutter can be made to obtain good mechanical performance using coating technology to improve cutting tool service life and mention
High machining efficiency, it is the material surface treatment process that RECENT DEVELOPMENTS is got up, and conventional coating technology can usually divide at present
For chemical vapor deposition (CVD) technology and physical vapour deposition (PVD) (PVD) technology two major classes, for CVD technology, due to coating
And its tool higher with substrate combinating strength has good wearability, and therefore, is widely used in the surface of hard alloy cutter
Processing, however there is also treatment temperature height for CVD technology, and cutter material bending strength is easily caused to decline and easily lead to cutter use
When the problems such as generating micro-crack seriously restrict its development, and for PVD technique, due to can be significantly using PVD technique
The cutting ability of high-speed steel tool is improved, process temperature control is at 500 DEG C hereinafter, at 600 DEG C or less to cutter
The bending strength of material has also obtained faster development without influence for CVD technology, however this technology there is also
Therefore the not high problem of conjugation also constrains its development from still further aspect, thus how can improve bond strength and
It is an insoluble technical problem that cutter anti-bending strength, which can be improved, later it has been proposed that CVD and PVD are superimposed to form two kinds
The scheme of operating procedure, in practice it has proved that, since two kinds of techniques itself are difficult to carry out fusion development there are the restriction on attribute,
The technology is lukewarm always.
Summary of the invention
Bond strength can be improved the technical problem to be solved in the present invention is to provide one kind and improves cutter anti-bending strength
The high speed cutting tool based on PVD technique.
In order to solve the above-mentioned technical problem, the high speed cutting tool of the invention based on PVD technique, including substrate, coating
PVD coating outside substrate, the surface etch of PVD coating have rough irregular surface, and the periphery of PVD coating is coated with
Blending becomes high-strength composite layer 4 mutually for CVD coating 3, PVD coating 2 and CVD coating 3.
The substrate 1 is hard alloy or high-speed steel substrate.
The PVD coating 2 is nano coating, and overall thickness is 2-5 nanometers.
The CVD coating 3 is metal nitride, carbide or oxide.
A kind of manufacturing method of such as above-mentioned high speed cutting tool based on PVD technique, comprising the following steps:
A, PVD coating paste is deposited on substrate by common process；
B, after base material deposited PVD coating using etching machine to PVD coating surface perform etching irregular surface crater and
Protrusion,
C, CVD coating is deposited on outside PVD coating using wet-blasting operation on product in stepb, is obtained
The compression stress of 1600-1700MPa.
The present invention has the advantages that
By the CVD coating of outer layer, higher reaction temperature and in the faster deposition rate short time in manufacturing process
CVD coating can have been deposited；Higher depositing temperature makes gas molecule or atom in the absorption of PVC coating surface and diffusion
To reinforce, chemical reaction is more abundant, so CVD coating and the binding force of the PVC coating Jing Guo surface etch are also stronger, thus
Thicker coating can be deposited, especially on the outside by the setting of CAD coating, on the one hand, PVD technique is utilized to the pre- place of substrate
Reason protection, reduces influence of the higher temperature to substrate, substantially increases cutter material bending strength, between coating and matrix also not
η phase can be generated, application range is expanded；Still further aspect is especially dexterously applied CVD coating and PVD by lithographic technique
Layer blending improves compound ability and avoids coat inside in tensile stress state, and cutter is made to generate micro-crack when in use, and
PVD coat inside is in compressive stress state, and internal micro-crack can be automatically repaired, and extends service life.
