The volume fraction stating tungsten carbide particle 3 is 70%~95%.
In the present embodiment, the fundamental tissue of blade body 1 is martensite, a small amount of carbide and a small amount of retained austenite.
The present invention provides a kind of lathe tool blade, and including blade body 1, blade body 1 surface is provided with multiple depression tubular body
4, and blade body 1 surface and depression tubular body 4 inner surface be equipped with tungsten carbide enhancement layer 2, as such, it is possible to pass through tungsten carbide
Enhancement layer 2 is effectively increased the surface recombination thickness of blade body 1, improves anti-wear performance and the toughness of lathe tool blade.
The present invention provides the preparation method of a kind of lathe tool blade, mainly comprises the steps that
Step 1: the surface of blade body is processed.
Wherein, the material of described blade body includes tungsten system high-speed steel.
Concrete, use acetone to clean on the surface of described blade body.
Step 2: the blade body after using laser-beam drilling machine to process surface is punched, and to the blade after punching originally
Body carries out pickling successively, is washed to neutrality, ultrasonic waves for cleaning, obtains the blade body with depression tubular body.

Surface concentration of carbon is relatively low.
If it should be noted that the mass fraction of the carbon of the present invention is chosen as the quality that reason is that carbon of 0.9%~1.0%
Mark is more than 1.0%, then carbon diffusion velocity in turning cutter body is accelerated, and diffusion depth increases, and is so unfavorable for that tungsten carbide strengthens
The raising of middle tungsten carbide volume fraction;If the mass fraction of carbon is less than 0.9%, turning cutter body surface carbon concentration can be caused relatively low.
It should be noted that the Preset Time of the present invention be chosen as 10min~35min reason is that if temperature retention time is big
In 35min, then tungsten carbide can be concentrated to turning cutter body internal diffusion, is so unfavorable for keeping the height of tungsten carbide in tungsten carbide enhancement layer
Volume fraction;If temperature retention time is less than 10 min, then the carbon in carburized layer can not react completely, thus affects tungsten carbide enhancement layer
Reinforced effects.
Step 4: carry out the blade body with carbide layers successively making annealing treatment, grade quench processes and three low temperature
Temper, obtains the lathe tool blade with tungsten carbide enhancement layer.
Wherein, described hierarchical temperature is 620 DEG C.
Concrete, the blade body with carbide layers is made annealing treatment at 880 DEG C, and is incubated 3h, then 840 DEG C
Lower preheating, then at 1280 DEG C, heat grade quench process, at 560 DEG C, finally carry out three lonneals process, and be tempered
Insulation 1h, finally gives the lathe tool blade with tungsten carbide enhancement layer.
The invention provides the preparation method of a kind of lathe tool blade, first, under vacuum condition or inert gas shielding, adopt
Form several depression tubular bodies on the surface of blade body with laser-beam drilling machine, and can to the spacing between depression tubular body,
The degree of depth and the caliber of depression tubular body are adjusted;Then, blade body is carried out under preset temperature and Preset Time carburizing
And insulation so that tungsten atom and carbon atom react generation tungsten carbide under solid state temperature, it is possible to according to the depression tubulose accomplished fluently
Body limits the diffusion of tungsten carbide, it is achieved that in blade body, tungsten carbide increases the preparation of layer, and it can be effectively increased blade body
Surface recombination thickness, improve the anti-wear performance of lathe tool blade and comprehensive serviceability;And the tungsten carbide particle in the present invention
And it is metallurgical binding between blade body, is firmly combined with, tungsten carbide particle difficult drop-off;Meanwhile, when can preset by controlling carburizing
Between and preset temperature, the regulation of laser boring parameter control the grain volume fraction of tungsten carbide enhancement layer, distribution and form, reach
The performance alternate to tungsten carbide enhancement layer and blade body is optimal.
