Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of wear-reducing alloy layer surfacing on the surface of steel tools or parts in order to overcome the disadvantage that the wear resistance and wear reduction of the current surfacing wear-resistant alloy can not be balanced. Grinding surfacing flux-cored wire, while effectively preventing the wear of tools or parts themselves, does not increase or even reduce the wear of other parts or components in contact with it

Abstract

The invention relates to an iron-based abrasion resisting and reducing surfacing flux-cored wire. The current abrasion resistant surfacing welding wires and alloys have many types; some abrasion resistant surfacing welding wires and alloys have high abrasion resistance and can protect the surfaced tools or parts, but have poor abrasion reduction performance and cannot effectively prevent other contacted parts or components from being abraded; some surfacing alloys have the abrasion reduction performance but lose the abrasion resistance. The iron-based abrasion resisting and reducing surfacing flux-cored wire comprises a low-carbon steel sheathing, and flux-cored powder; and the wire includes the following alloy elements in percentage by weight: 0.2 to 0.8% of carbon, 5 to 20.0% of chromium, 1.0 to 7.0% of titanium, 0.3 to 5.0% of boron, 0.1 to 1.5% of silicon, 0.2 to 2.0% of manganese, and the balance of iron. According to the iron-based abrasion resisting and reducing surfacing flux-cored wire, the abrasion resisting surfacing alloy has high hardness, and good toughness and matching performance, and is hard to crack, and has both the abrasion resistance and the abrasion reduction performance, and achieves high abrasion resistance along with high abrasion reduction performance.

Description

technical field [0001] The invention belongs to the fields of machinery, steel materials, etc., and in particular relates to a wear-resistant and wear-reducing surfacing flux-cored welding wire for surfacing wear-resistant alloy layers on the surface of steel tools and mechanical parts. Background technique [0002] The wear-resistant surfacing welding wire is surfacing on the surface of the tool or part to form a wear-resistant alloy layer to protect the tool or part from wear. If the tool or part is in contact with other parts or components during work, the surfacing welding is also required Grinding alloys do not increase or even reduce the wear of other parts or components. There are many types of wear-resistant surfacing welding wires and alloys, some of which have good wear resistance and protect the tools or parts to be surfacing, but because of their high brittleness, low toughness, cracks, and easy peeling, they cannot effectively prevent the welding wires and alloy...
