Problems solved by technology

[0003] In the prior art, the raw materials of aluminum bronze in the supply state are generally directly used for processing. This method is simple, direct and formable, and is suitable for most occasions. However, due to the different states of the aluminum bronze in the supply state and the relatively uniform structure Poor, it is not very suitable for the friction and wear conditions where the performance is determined by the microscopic performance

Embodiment 1

[0021] A high wear-resistant aluminum bronze is finally obtained after solid solution-hot water cooling-cold treatment-aging heat preservation-spheroidizing slow cooling treatment with QAl10-4-4 as raw material, and the internal strengthening phase is in a spheroidized state.

[0022] The manufacturing method of the above-mentioned high wear-resistant aluminum bronze comprises the following steps:

[0023] 1) Preparation before production

[0024] ① Raw material preparation: Prepare the aluminum bronze QAl10-4-4 supply state round bar with a diameter of Φ30mm;

[0025] ②Equipment and tooling preparation: prepare a high-temperature protective atmosphere heating furnace, a pure water tank with built-in heating equipment and mixing equipment, a medium-temperature protective atmosphere heating furnace, and a freezer;

[0026] ③ Auxiliary process material preparation: prepare a sufficient amount of argon;

[0027] 2) modified

[0028] ① Put the aluminum bronze QAl10-4-4 supply s...

Embodiment 2

[0035] The whole is consistent with Example 1, the difference is:

[0036] The manufacturing method of the above-mentioned high wear-resistant aluminum bronze comprises the following steps:

[0037] 1) Preparation before production

[0038] ① Raw material preparation: prepare aluminum bronze QAl10-4-4 supply state round rods with a diameter of Φ40mm;

[0039] 2) modified

[0040] ① Put the aluminum bronze QAl10-4-4 supply state round bar prepared in stage 1) step ① into the high-temperature protection atmosphere heating furnace prepared in stage 1) step ②, pass in a sufficient amount of argon, and then heat it to 985 ° C, Keep warm for 100 minutes to obtain a solid solution bar, and then take it out of the oven;

[0041] ② While step ① is in progress, turn on the heating equipment in the pure water tank prepared in step 1) at the same time to the water temperature of 80°C;

[0042] ③ Turn on the stirring equipment in the pure water tank, stir at a rate of 50rpm, and then t...

Abstract

The invention discloses high wear resistance aluminium bronze and a manufacturing method thereof. The high wear resistance aluminium bronze is made from QAl10-4-4 as raw materials, and finally obtained after the processes of solid solution, hot water cooling, cold treatment, aging heat preservation and spheroidizing and slow cooling treatment. The strengthening phase in the high wear resistance aluminium bronze is of the spheroidized state. The high wear resistance aluminium bronze has uniform structure, high hardness, good abrasive resistance, and spheroidized structure.

Description

technical field [0001] The invention relates to the field of heat treatment modification of copper materials, in particular to a high wear-resistant aluminum bronze and a manufacturing method thereof. Background technique [0002] Aluminum bronze is a copper-based alloy with aluminum as the main alloying element. It is an aluminum bronze containing iron and manganese elements. It belongs to high-strength heat-resistant bronze. The aluminum content generally does not exceed 11.5%. and other elements to further improve performance. Aluminum bronze can be strengthened by heat treatment, its strength is higher than that of tin bronze, and its resistance to high temperature oxidation is also better. [0003] In the prior art, the raw materials of aluminum bronze in the supply state are generally directly used for processing. This method is simple, direct and formable, and is suitable for most occasions. However, due to the different states of the aluminum bronze in the supply st...
