Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in detail below in conjunction with specific examples.

[0024] Such as figure 1 As shown, the present invention discloses a wear-resistant and corrosion-resistant circular chain, which is composed of a plurality of improved coatings on the surface of the chain. The chain includes a base 1, and on the outside of the base 1, Al-Fe layer 2 and a rare earth silicon aluminum layer 3 , the rare earth silicon aluminum layer 2 is coated on the outside of the substrate 1 , and the Al—Fe layer 3 is coated on the outside of the rare earth silicon aluminum layer 2 . Preferably, the thickness of the rare earth silicon aluminum layer is 100-130 μm, and the thickness of the Al-Fe layer is 10-40 μm. Further, the Al-Fe layer includes FeAl layer, Fe3Al layer and Fe5Al layer.

[0025] A preparation method of the above-mentioned wear-resistant and anti-corrosion circular chain, comprising the following steps: ...

Abstract

The invention discloses a wear-resistant and corrosion-resistant ring chain. The wear-resistant and corrosion-resistant ring chain comprises an improved plating layer and a chain body, wherein the improved plating layer is arranged on the surface of the chain body; the chain body comprises a base body; an Al-Fe layer and a rare earth silicon-aluminum layer are successively arranged on the outer side of the base body from inside to outside; the Al-Fe layer wraps the outer side of the base body; and the rare earth silicon-aluminum layer wraps the outer side of the Al-Fe layer. The invention further discloses a preparation method of the wear-resistant and corrosion-resistant ring chain. The Al-Fe layer and the rare earth silicon-aluminum layer are successively arranged on the surface of the ring chain from inside to outside, the surface structure of the ring chain is improved, and thus, the corrosion resistance and hardness of the surface are improved. The method is economical, can further be used as a chain in the special field such as ocean fishing chains, and has high promotional value.

Description

technical field [0001] The invention relates to the technical field of circular chain production, in particular to a wear-resistant and corrosion-resistant circular chain and a preparation method thereof. Background technique [0002] The material of the round link chain generally requires a strength level of 80 and above, and large diameter chains are mostly made of 23MnNiMoCr54 steel, while 20Mn2 or 25MnV is mainly used to produce strength levels below 80 and small diameter chains. [0003] Mining round link chain is a kind of round link chain, mainly used in coal mines, and is an important consumable part on the scraper machine of coal mining equipment. Its service life directly determines the production efficiency of the scraper machine. Compared with other circular chains, the mining circular link chain is used in a harsher environment. First of all, the mining circular link chain is subjected to a huge tensile stress at the initial stage of the scraper machine. Theoret...
