Embodiment Construction
[0012] 1. Select titanium-silver alloy powder with a titanium content of 30%, add niobium powder to the titanium-silver alloy powder, the weight of the niobium powder is 0.5% of the weight of the titanium-silver alloy powder, and then mix in aluminum powder, the weight of the aluminum powder is the weight of the titanium-silver alloy powder 3% of the flaky body metal binder; put the flaky body metal binder into the bottom of the cylindrical heating block made of graphite material, inject the cutting layer powder into the cylindrical heating block, and the cutting layer powder is in the On the metal binder of the flake, then inject the powder near the base layer into the cylindrical heating block, the powder near the base layer is on the powder of the cutting layer, and then inject the powder of the far base layer into the cylindrical heating block, the powder of the far base layer is on the powder near the base layer The weight ratio of metal binder to cutting layer powder i...

The invention discloses a method for preparing a titanium-silver material, and belongs to the technical field of material manufacturing. Titanium-silver alloy powder, niobium powder and aluminum powder are mixed to be pressed into a plate metal bonder; the metal bonder is placed into the bottom of a barrel-shaped heating block made of graphite materials, cutting layer powder is injected into the barrel-shaped heating block, near basic-level powder is injected into the barrel-shaped heating block, and far basic-level powder is injected into the barrel-shaped heating block; the cutting layer powder is prepared through coal oxidation ceramic powder and cubic boron nitride micro powder; the heating block is placed into a high-temperature and high-pressure device, the pressurizing is carried out gradually so that pressure can be increased into 30 kilopascals, temperature rise is carried out at the same time, and after naturally cooling, a cutting tool material is formed by the alloy of the metal bonder and the material powder. A produced cutter is made of pig iron with the type: Cq21-40(GOST1412-79), the machining mode is v=205 m / min, s=0.3 mm / r, t=1.5-2.0 mm, and under the non-cooling condition, HB is 220, and the service life is 60 minutes.
Description
technical field [0001] The invention belongs to the technical field of material manufacturing, and relates to a method for preparing cutting tool materials. Background technique [0002] The existing cutting tool material preparation method is mainly to mix and heat several metal materials, and the cutting tool is easy to wear and has a short service life during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of superhard titanium-silver alloy material. [0004] The scheme that the present invention solves technical problem is to finish through the following steps: [0005] 1. Preparation of metal binder [0006] Select titanium-silver alloy powder with a titanium content of 30-75%, add niobium powder to the titanium-silver alloy powder, the weight of the niobium powder is 0.5-1% of the weight of the titanium-silver alloy powder, and then mix in aluminum powder, the weight of the alum...
