Method for manufacturing preformed component of partially reinforced metal matrix composite product

Abstract

A method of producing prefabricated members intensified partly with metal composite material. It comprises:1)preparing sizing material, mixing 100 wild-phase material, 1-7 natural cellulose, 3-9 water glass, 1-7 aluminum phosphate and 105-123 dispersing solution; the wild-phase material selected from aluminum oxide, silicon oxide, silicon carbon, boron oxide, graphite monomer or their combination; the dispersing solution prepared by 0.5-3% polyvinyl alcohol and water, or 0.5% polyacrylamide solution; 2) manufacturing blanks, immersing porous material into the sizing material, airdrying and hardening at room temperature; 3)baking, baking blanks at 60-100degree C for 1-2hours, 200degree C-220degree C for 1-2hours, 400degree C-450degree C for 2hours, heating to 900degree C-1000degree C and baking for 2-3hours, sintering 2-8 hours, then slowly cooling to the room temperature with the oven.

Description

technical field [0001] The invention belongs to the technical field of mechanical parts manufacturing technology, and in particular relates to a method for preparing a pre-component of a locally reinforced product of a metal matrix composite material Background technique [0002] A basic goal of the designer is to produce a low cost product with uniform performance. The requirements for a product's performance, including physical properties, chemical or mechanical properties, such as thermal expansion coefficient, friction and wear resistance, heat resistance, corrosion resistance and rigidity, may be significantly different for different parts. So far, designers are basically limited to selecting a single material to meet the highest standard requirements for a specific purpose, resulting in an unreasonable situation in resource utilization. [0003] In the early 1980s, people invented the squeeze casting process, also known as the liquid metal die forging method, which ca...

Problems solved by technology

Some known composite material pre-component manufacturing methods based on slurry pressurization or vacuum filtration methods are difficult to stably control the set volume ratio of the composite components, and it is difficult to achieve uniform distribution of the composite components, and generally Both of them have a long cycle in the billet making stage and many operating links, resulting in low production efficiency and high production costs of pre-components, which have become the main factors restricting the mass application and market competitiveness of locally reinforced metal matrix composite products.
