Embodiment 1

[0025] The method for smelting metal-based nanocomposites is to add diamond powder or ceramic powder, which accounts for 0.5‰ to 10% of the total weight of 15Mn and has a particle size of 1nm to 10μm, into a smelting furnace during the 15Mn smelting process.

Embodiment 2

[0027] The metal-based nanocomposite smelting method is that during the aluminum (Al) smelting process, diamond powder or ceramic powder (or other metal powder) accounting for 0.5‰ to 10% of the total weight of aluminum and a particle size of 1nm to 10μm is added to the smelting furnace It is smelted in the middle of the furnace, and it is the finished product when it comes out of the oven.

Abstract

The present invention relates to smelting process of nanometer metal-base composite material, and features that during smelting, heterogeneous nanometer powder is added into the smelting furnace for composite smelting. The added powder is diamond powder or ceramic powder of granularity of 1 nm to 10 micron and accounting for 0.05-10 % of the smelted metal. The nanometer metal-base composite material of the present invention has completely new micro structure and excellent mechanical performance, including greatly raised hardness, strength, wear resistance, corrosion resistance and fatigue resistance.

Description

technical field [0001] The invention relates to a metal material smelting method, in particular to a metal nano composite material smelting method. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the consumption of resources and energy on which human beings depend is increasing rapidly. The environment causes damage and pollution. Therefore, rational utilization of resources, reduction of energy consumption, research and development of new materials, and development of new energy sources have become national policies. Nanomaterials are the best among new materials, and the development and application of nanotechnology have favorably promoted the development of industrial and agricultural production. At present, the bulk of nano-metals and metal-based nanocomposites available for engineering use have not yet been successfully developed. Contents of the invention [0003] The object of the ...
