Abstract

The invention discloses an aluminum bronze material and a preparation process thereof, and belongs to the field of metal materials. The aluminum bronze material comprises the following raw materials of an aluminum bronze matrix with pores, a porous carbon material and a grease mixture, and the grease mixture comprises grease and nanoparticles, and the invention also discloses the preparation process of the aluminum bronze material. The preparation process comprises the steps of preparing the aluminum bronze matrix with pores; mixing the grease with the nanoparticles to obtain the grease mixture; carrying out ultrasonic mixing on the grease mixture and the porous carbon material to obtain a mixture; and dipping the aluminum bronze matrix in the mixture, and carrying out seepage under pressure to obtain the aluminum bronze material. According to the aluminum bronze material and the preparation process thereof, the grease mixture is added, a pore defect existing in a traditional aluminumbronze material is fully utilized, before seepage, an anionic surfactant is added into the mixture to enable the mixture to have negative charges, the surfaces of pores of the aluminum bronze matrix have positive charges, through the electrostatic interaction, the mixture can permeate into the pores in the aluminum bronze matrix more easily, and the seepage effect is more uniform.

Description

technical field [0001] The invention relates to metal materials, in particular to an aluminum bronze material and a preparation process thereof. Background technique [0002] Aluminum bronze plays a very important role in the machinery industry, especially when the aluminum content is about 10%, it has good mechanical strength, wear resistance, seawater corrosion resistance and cold resistance, so aluminum bronze is widely used in aviation Aerospace and ocean engineering and other fields. However, traditional cast aluminum bronze is prone to defects such as internal defects, holes and surface inclusions, and it is difficult to manufacture parts with complex and fine structures. [0003] In the existing casting process, the amount of dissolved oxygen in the aluminum bronze alloy liquid is small, and the water vapor and hydrogen in the alloy liquid are the main reasons for the formation of pores in aluminum bronze, and hydrogen is the most harmful gas in aluminum bronze, whic...
