Th...

Embodiment 2

[0034] Example 2: In figure 2 in, with figure 1 The difference is that the induction cladding equipment is not installed in a vacuum sealed enclosure.

[0035] When work starts, first put Cr 12 MoV cold work die steel is prepared into powder, or metal and alloy powder according to Cr 12 The alloy composition of MoV cold work die steel material is prepared, and then 0.4% Y is added in it according to the mass percentage 3 o 2 , 0.6% MgO, 0.5% CaF 2 , 0.25% Nb, 0.30% TiB, 0.15% TiN, 0.25% VN, and the rest is Fe. After proportioning its component raw materials, put them into a high-energy stirring ball mill for stirring ball milling to prepare micro-nano or nano-alloy powders; then Add 8% rosin oil binder to the above alloy powder, make it into granules or powder after mixing, dry it in the air or dry it at a temperature of 80 degrees, add it to the granule feeder, and clean the surface The processed workpiece 4 is placed in the forming mold 7, the forming mold 7 is fixed ...

Embodiment 3

[0037] Example 3: image 3 It is a vacuum induction melting equipment. The equipment consists of box cover 17, cladding layer 18, workpiece 19, protective coating 20, frequency conversion induction heater 21, box body 22, manufacturing sand 23, vacuum pump valve 24, vacuum pump motor 25, vibrator 26, frequency conversion induction heater 21 is installed inside the box body 22, and the vibrator 26 is installed on the bottom or side of the box body 22. The vibrator 22 is mechanical vibration or ultrasonic vibration. The frequency of the frequency conversion induction heater 21 can be divided into steps from 200Hz to 500kHz. To adjust, the vacuum pump is installed on either side of the casing 22, and is connected with the vacuum pump valve 24 and the vacuum pump through a pipeline.

[0038] At the beginning of the work, the high chromium cast iron is first prepared into powder, or metal and alloy powder are used according to Cr 12 The alloy composition of MoV cold work die stee...

Abstract

The invention relates to a micro-nano-alloy bimetal composite material preparation technique and a device thereof; one of wear-resistant and corrosion-resistant ferrous metal material, non-ferrous metal material and various self-fluxing alloy is prepared into power; then, the powder is added with less than or equal to 0.8% of one or combination in CeO2, Y2O3 and La2O3, 0.3-1.5% of MgO, 0.3-1.8% of CaF2, 0.0-1.5% of B, 0.1-0.8% of Nb, 0.1-1.0% of Ti, 0.1-2.0% of grain refining and recrystallization inhibitor according to the mass percent; or the powder is added with 1-40% of carbide, nitride, micro-nano or nano particles of boride; and the mixture is put into a high-energy stirring ball grinding mill for grinding and ball milling, so that the micro-nano or nano alloy powder can be prepared. A variable frequency induction heating device is adopted for cladding and melting vacuum or inert gas, so that a workpiece can be melted and coated with a micro-nano or nano scale alloy cladding layer which has the grain size of 0.1-35mm and is wear-resistant and corrosion-resistant, and the bimetal composite material can be prepared. The invention overcomes the defects in various coating techniques in China at present, can complete the preparation of the workpiece with the cladding layer having high thickness for once, does not need repeated coating and sintering, has high material utilization rate, low machining allowance and preparation cost, simple preparation technique and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of metal composite materials, and relates to a micro-nano alloy bimetal composite material and a preparation method thereof, in particular to a preparation process and equipment for a micro-nano alloy bimetal composite material. Background technique [0002] Bimetallic composite materials are composites of two or more metal materials with different properties through a certain process, so that different parts of the material or parts have different properties to meet the requirements of use. It is different from dispersion-strengthened materials. Layered composite materials are not one material dispersed in another material, but each component material forms one or several wholes, and the components are composited by interface bonding. One, the composite methods mainly include liquid-solid composite, liquid-liquid composite, solid-solid composite and so on. It is usually an alloy with high mechanical proper...
