This PVD coating metal cutting saw bit, including being circular shape saw bit body, the body outside is equipped with and is annular cutting part, the cutting part on form anchor coat and functional layer in proper order through PVD vacuum coating, anchor coat thickness be 0.1 -1um, functional layer thickness be 2 -5um. This PVD coating metal cutting saw bit adopts the PVD technique to form anchor coat, functional layer respectively at the cutting part surface, can reduce on the one hand and scribble ply stress improvement coating cohesion, on the other hand, alloy through zr, cr, ti and al and si carry out the coating film, the hardness that promotes the saw bit with reduce coefficient of friction in, still promoted the oxidation resistance of saw bit.
Description
Technical field
This utility model belongs to technical field of surface, relates to the process for treating surface of a kind of Metal Cutting saw blade, particularly a kind of siliceous PVD coating metal cast-cutting saw slice.
Background technology
Saw blade is the general designation of the thin slice circular knives for cutting solid material.Saw blade can be divided into the diamond saw blade for stone material cutting, the HSS sawblade cut for metal material；For the hard alloy saw blade that solid wood, furniture, wood-based plate, aluminium alloy, aluminium section bar, radiator, plastics, plastic-steel etc. cut.Owing to purposes is different, therefore the material of saw blade and hardness also differ.
The sawing of metal material is normally used bands for band and saw blade.Bands for band versatility is good, can the bigger workpiece of sawing, but for saw blade, efficiency and the tangent plane quality of sawing are nothing like the latter.Saw blade web for sawing metal is applied widely at mechanical processing industry, and in order to realize low-carbon (LC), environmental protection and light-weighted target, increasing high rigidity, high-strength material are used, and saw blade cutting is a new challenge by this.And on the other hand, very thin pipe fitting is carried out sawing, and ensure that otch is indeformable, also it is a challenge to saw blade cutting.
Utility model content
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that the Metal Cutting saw blade that a kind of high life, cut quality are good.
The purpose of this utility model can be realized by following technical proposal: a kind of PVD coating metal cast-cutting saw slice, including rounded blade body, it is characterized in that, described outer body is provided with ringwise cutting part, described cutting part sprays plated film by PVD and sequentially forms binder course and functional layer, described joint thickness is 0.1-1um, and described functional layer thickness is 2-5um.
The purpose of binder course is in that between cutting part and functional layer to form transition, improve the adhesion of cutting part and functional layer.The purpose of functional layer is in that to promote hardness and the wearability of cutting part, and reduces dry friction coefficient.
In above-mentioned PVD coating metal cast-cutting saw slice, described binder course adopts Cr, Ti, Al or Zr, or two or more alloy in Cr, Ti, Al and Zr forms as the bombardment of target source.
In above-mentioned PVD coating metal cast-cutting saw slice, described functional layer adopts Cr, Ti, Al or Zr, or the alloy that one or more in Zr, Cr, Ti and Al are with Si forms as the bombardment of target source.The reacting gas passed into is high-purity argon gas (Ar), high pure nitrogen (N2) or hydrocarbon class gas (CH4 etc.).
Compared with prior art, this PVD coating metal cast-cutting saw slice adopts PVD technique to form binder course, functional layer respectively at cutting part outer surface, can reduce coating stress on the one hand and improve coating binding force；On the other hand, by Zr, Cr, Ti and Al and Si alloy carry out plated film, promoting the hardness of saw blade and reducing while coefficient of friction, also improve the non-oxidizability of saw blade.

Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this PVD coating metal cast-cutting saw slice, including rounded blade body 1, described outer body is provided with ringwise cutting part 2, described cutting part sprays plated film by PVD and sequentially forms binder course 3 and functional layer 4, described joint thickness is 0.1-1um, and described functional layer thickness is 2-5um.
The purpose of binder course is in that between cutting part and functional layer to form transition, improve the adhesion of cutting part and functional layer.The purpose of functional layer is in that to promote hardness and the wearability of cutting part, and reduces dry friction coefficient.
The PVD coating process of this PVD coating metal cast-cutting saw slice is as follows: first by saw blade through cleaning, drying, is arranged on special fixture, loads in vacuum pvd plated film chamber；Open pvd equipment, be evacuated to 1.0x10-3More than Pa vacuum, starts firing equipment and web plate is heated to technological temperature 200-400 degree Celsius.Continue to be evacuated down to 1.0x10-3More than Pa vacuum, starts plated film.
Ion Cleaning: purpose is to remove the water stain remaining dirt that waits on workpiece, activating surface atom, prepares for plating binder course.Process conditions are to be evacuated down to 1.0x10-3More than Pa vacuum, passes into the argon (Ar) that purity is 99.999%, and Stress control is at 1-2pa, open arc source electric current and control at 40-80A, opening bias voltage and control at 300-1000V, Duty ratio control is at 30-50%, and the process time is less than 30min.
Plating binder course: process conditions are to be evacuated down to 1.0x10-3More than Pa vacuum, pass into the argon (Ar) that purity is 99.999%, Stress control is at 0.1-1pa, opening metal electric arc target source includes Cr, Ti, Al, Zr etc. and alloy thereof, open bias voltage and control at 100-300V, Duty ratio control is below 80%, and the THICKNESS CONTROL of binder course is at 0.1-1um
Plating functional layer: process conditions are to be evacuated down to 1.0x10-3More than Pa vacuum, pass into the process gas that purity is 99.999%, including argon (Ar), nitrogen (N2), methane (CH4) etc., Stress control is at 0.5-1pa, open electric arc target source such as Cr, Ti, Al, Zr etc. and the alloy with Si thereof, opening bias voltage and control at 10-200V, Duty ratio control is more than 50%, and the THICKNESS CONTROL of functional layer is at 2-5um.
After above-mentioned process of surface treatment, the saw blade after processing with process for treating surface of the prior art contrasts, and draws following table:
In table, working (machining) efficiency is that industrial stainless-steel thin-wall pipe calculates according to processing 3.Can being learnt by upper table, this PVD coating metal cast-cutting saw slice adopts PVD technique to form binder course, functional layer respectively at cutting part outer surface, can reduce coating stress on the one hand and improve coating binding force；On the other hand, by Zr, Cr, Ti and Al and Si alloy carry out plated film, promoting the hardness of saw blade and reducing while coefficient of friction, also improve the non-oxidizability of saw blade.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount the scope that appended claims is defined.
