Embodiment 1

[0034] After weighing the metal block raw materials by electronic balance, 23% Fe was prepared according to the mass percentage. 2 B, 21% Fe 4 N, 18% MnAl 4 , 16% of V 6 Si 5 , 9% AlMo 3 , with a margin of α-Nb 5 Si 3 alloy composition.

[0035] Put the various materials in the above proportions into the chamber of the non-consumable arc melting equipment. After the chamber is evacuated into a high vacuum, it is filled with argon (purity: 99.999wt%) protective atmosphere to stabilize the arc. Adjust the current intensity to control the temperature of arc melting, and obtain a primary alloy ingot with uniform composition after repeated melting.

[0036] Put the alloy ingot into the quartz crucible of the gas atomization powder making equipment, close the equipment and evacuate to 3×10 -2 Pa, filled with argon to normal pressure. In order to ensure the purity of the gas in the equipment, repeat the above process three times. Set the injection pressure to 5MPa and the o...

Embodiment 2

[0039]After weighing the metal block raw materials by electronic balance, 26% Fe was prepared according to the mass percentage. 2 B, 24% Fe 4 N, 19% MnAl 4 , 16% of V 6 Si 5 , 11% AlMo 3 , with a margin of α-Nb 5 Si 3 alloy composition. Next, various materials in the above proportions are put into the chamber of the non-consumable arc melting equipment, and an alloy ingot with uniform composition is obtained by arc melting. Before melting the material, the chamber is evacuated to a high degree of vacuum, and then filled with an argon protective atmosphere to stabilize the arc. Adjust the current intensity to control the temperature of arc melting, and after repeated melting, a block with uniform alloy distribution is obtained. Then, put the alloy ingot into the quartz crucible of the gas atomization powder making equipment, close the equipment and evacuate to 3×10 -2 Pa, filled with argon to normal pressure. In order to ensure the purity of the gas in the equipment, ...

Abstract

The invention discloses a spraying material for the inner surface of an electricity channel of a diamond type power distribution network, a preparation method thereof and the electricity channel. The spraying material is prepared from the following components in percentage by mass: 23% to 26% of Fe2B, 21% to 24% of Fe4N, 17% to 20% of MnAl4, 14% to 17% of V6Si5, 8% to 11% of AlMo3 and the balance of alpha-Nb5Si3. The spraying material provided by the invention is sprayed to the inner surface of the electricity channel of the diamond type power distribution network through hypersonic flame, a compact amorphous coating can be obtained at a relatively slow cooling rate, the wear resistance is high, the electricity channel is not damaged by a steel wire rope, the free bending of a PVC pipe is not influenced, stability and reliability are achieved, and the construction progress can be effectively accelerated and accident potential can be avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-wear materials for electric power engineering, and relates to a material for spraying the inner surface of a power pipe for a diamond-shaped distribution network, in particular to a layer of highly wear-resistant amorphous powder quickly formed in the pipe. Background technique [0002] At present, with the general improvement of the quality of life of urban and rural residents, the requirements for living conditions and living environment are getting higher and higher. The diamond-shaped distribution network uses cable power supply, which is a more beautiful power supply method. The power cable laying method generally chooses pipe laying, trench laying, tunnel laying, direct burial laying, underwater laying and so on. Among them, the laying of power pipes is currently the most used method in cities. It is suitable for the frequent construction of cities today, and can make better use of various terr...
