Alloy coating production technique for alloy bush

Abstract

The invention discloses an alloy coating production technique for alloy bush. The alloy coating production technique includes steps of (1) heating a crucible, adding 2-3 kg of flux; after heating the flux to 1120-1420 DEG C, completely cleaning the bottom part and four sides of the crucible, and blowing by a gas gun; (2) weighing alloy powder and preheating to 300-350 DEG C, and adding to a melting furnace to melt for 3-5 h; (3) after the alloy powder is completely melted, raising temperature of the melting furnace to 1100-1200 DEG C, and then raising the temperature of the melting furnace to 1300-1400 DEG C, and installing a mechanical stirring device to stir at 60 r / min for 30 min; and then adjusting the stirring speed to 80 r / min and stirring for 15 min; (4) adding the flux obtained in step (1) to the melting furnace in step (3), and then stirring at 40 r / min and refining for 3-5 min; taking out of the stirring device; (5) preheating hexachloroethane degassing agent at 80-120 DEG C and covering by a bell jar at 80-120 DEG C, and pushing to the bottom part of the crucible and degassing for 8-10 minutes; and then slagging off artificially.

Description

technical field [0001] The invention relates to the technical field of alloy bushings, in particular to an alloy coating production process for alloy bushings. Background technique [0002] Alloy is a common lightweight metal material. It is widely used in industries such as automobiles, ships, aerospace, machinery, and communications. It has the characteristics of good processing performance and light weight. With the requirements of lightweight and low energy consumption, alloys The demand continues to expand, and some countries also use alloys to build warships. [0003] With the rapid development of the global economy, the use of automobiles is increasing year by year, and the competition among major automobile manufacturers is becoming more and more intense. Therefore, the service life of the hinge parts of automobiles is increasingly demanding. For about a year, the disassembly process of replacing the alloy bushing is extremely cumbersome, and it increases the mainte...
