Abstract

The invention provides a motor cylinder block material. The motor cylinder block material includes a matrix material and modified nanoparticles added into the matrix material. The matrix material is iron-base alloy. The modified nanoparticles are prepared through the following method. The method includes the steps that S1, the Tris reagent is dissolved into a graphene oxide solution, and the Tris reagent is added in an amount of 2-3 times of the mass of graphene oxide; S2, the ph value of the solution in the step S1 is adjusted to be 8-9; S3, dopamine is added into the solution of the step S2, the mass ratio of the dopamine to the graphene oxide is 1:(1-2.5), and the product is dried and pulverized after the stirring reaction lasts for a certain period of time; and S4, powder obtained in the step S3 is heat-treated at the temperature of 800-2000 DEG C under an argon atmosphere, and accordingly the modified nanoparticles are obtained.

Description

technical field [0001] The invention relates to a motor cylinder material. Background technique [0002] Motors are widely used in engineering machinery, construction machinery, metallurgical industry, and chemical industry, and the cylinder block, an important part, has to be considered in its application. The motor cylinder block not only has complex structure, numerous processes, difficult casting, high requirements for process equipment, but also strict requirements for wear resistance and thermal stability. With the development of motor technology, the quality, reliability and stability requirements of motor castings are further improved. At the same time, modern motor cylinders put forward higher requirements for the strength of materials. Contents of the invention [0003] The main purpose of the present invention is to provide a high-performance motor cylinder material and its preparation method. [0004] In order to achieve the above object, the present inventio...
