Built-in cylinder liner of automobile engine and powder metallurgy preparation method thereof
The invention discloses a built-in cylinder liner of an automobile engine and a powder metallurgy preparation method thereof. The cylinder liner is prepared from the following raw materials in parts by weight: 14-37 parts of silicon carbide, 13-32 parts of silicon nitride, 11-26 parts of silicon dioxide, 8-17 parts of zirconium silicate, 4-17 parts of zirconium oxide, 7-17 parts of nano copper oxide, 9-19 parts of nano graphene powder, 3-11 parts of nano aluminum silicate, 7-13 parts of nano magnesium oxide, 5-18 parts of a dispersing agent and 18-35 parts of water. Compared with the prior art, the built-in cylinder liner has the advantages that (1) the built-in cylinder liner of an automobile engine is applicable to heavy-load engines and aluminum alloy cylinder engines, and has strong abrasion resistance, high temperature resistance and excellent heat dissipation performance; (2) the built-in cylinder liner has good rigidity, strong toughness and strong compactness, and is convenient to assemble; and (3) the powder metallurgy preparation method of the built-in cylinder liner has simple process flow, short period and small energy consumption, and cannot easily cause environment pollution.
