Abstract

The invention discloses a preparation method for titanium copper alloy materials and belongs to the technical field of material manufacturing. Titanium copper alloy powder, niobium powder and aluminum powder are mixed and pressed into a sheet metal binder, the sheet metal binder is placed into the bottom of a cylindrical heating block made of graphite materials, cutting layer powder is poured into the cylindrical heating block, near-base-layer powder is poured into the cylindrical heating block, and then far-base-layer powder is poured into the cylindrical heating block; the cutting layer powder is made of carbon oxide ceramic powder and cubic boron nitride micro powder; the heating block is placed into a high-temperature high-pressure device, pressure is gradually increased to reach 30 kilopascals, temperature is increased at the same time, and the metal binder and the alloy of the material powder form cutting tool materials after natural cooling. A tool obtained based on the method machines pig iron Cq 21-40(GOST1412-79), and the HB is 220 and the service life is 60 minutes on the conditions that the machining mode is v=205 m / min, s=0.3 mm / circle and t=1.5 mm to 2.0 mm, and no cooling condition exists.

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 during use and has a short service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a superhard titanium-copper 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-copper alloy powder with a titanium content of 30-75%, add niobium powder to the titanium-copper alloy powder, the weight of niobium powder is 1-2% of the weight of titanium-copper alloy powder, and then mix in aluminum powder, the weight of aluminum powder i...
