Problems solved by technology

However, since aluminum is a relatively soft metal, its wear resistance is very poor, and the added elements in its alloy improve the mechanical strength to a certain extent, but the sensitivity to external force is still relatively large.
During its use, electric power fittings need to withstand large vertical loads and large swings. Many aluminum alloy electric fittings are severely worn shortly after use, which not only causes a lot of manpower and material resources , loss of financial resources, and great potential safety hazards

Abstract

The invention relates to the technical field of new material processing, and discloses a method for improving wear resistance of aluminum alloy electric power fittings. The method comprises the following steps: rapidly melting prepared ball-milled powder by using a plasma spraying technology to further form atomized molecules, spraying the atomized molecules to the surfaces of pretreated fittings,and rapidly condensing the atomized molecules to obtain a wear-resistant coating which plays an inert wear-resistant and corrosion-resistant barrier. The coating has a strong binding force with the surfaces of the aluminum alloy fittings, and a film layer is compact, has high hardness, and can withstand the impact of high-strength external force, so the surface performance of the fittings is comprehensively improved, and the safety and the service life of the electric power fittings are improved. The method can significantly improve the wear resistance of the aluminum alloy electric power fittings, solves the problem of no wear resistance of existing aluminum alloy electric power fittings, improves the surface strength and toughness, has stable chemical and mechanical properties, expandsthe application occasions, and significantly improves the economic and safety benefits.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a method for improving the wear resistance of aluminum alloy electric fittings. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Iron or aluminum metal accessories widely used in transmission lines are collectively referred to as fittings. There are many types of fittings with different uses, for example, various clamps for installing wires, various hanging rings for forming insulator strings, various crimping tubes and repair tubes for connecting wires, and various types of spacers for splitting wires In addition, there are various types of wire fittings used for poles and towers, as well as the size of the protective wires, which must cooperate with each other. [0003] Aluminum alloy power fitti...
