Abstract
The present invention relates to a metal component surface abrasion resistance strengthening material used for spray welding, more specifically to alloy powder used for spray welding. The present invention overcomes the defect of a poor combination property in the prior art. The present invention has the technical scheme for overcoming the defect in the prior art that the present invention is formed by mixing the following substances measured by parts by weight: 18 to 30 parts of Cr, 4 to 9 parts of Ni, 2 to 6 parts of Mn, 2 to 6 parts of Si and 2 to 4.4 parts of C. The present invention has the advantages that the present invention takes the basic alloy wear resistant and friction reducing requirements of new-type alloy into account, follows a balance wear design conception and a principle of stability, and has the advantage of favorable integrative performance, namely reasonable matching of abrasion resistance and friction reducing performance, favorable manufacturability and preferable abrasion resistance. The present invention has wide application range, and can be used for the surface abrasion resistance strengthening for a petroleum drill rod, a sucker rod, and other metal components which need wear resistance and friction reduction.
Description
Affiliated technical field:
The present invention relates to a kind of surfacing material of the wear-resisting reinforcement of metal component surface, be specifically related to a kind of surfacing powdered alloy.
Background technology:
The loss that hardware causes because of wearing and tearing is quite huge, and according to statistics, in industrially developed country, the financial loss that causes owing to wearing and tearing accounts for 1～4% of whole national economy budget.In China; because scientific and technological level is low; of most mechanical component itself is several times lower than even tens times than external like product in life-span; it is to scrap in advance because of the resistance to abrasion difference that a considerable part is wherein arranged; this has not only consumed a large amount of steel spare parts; and, influenced production efficiency owing to the part reason need be shut down maintenance, wasted lot of manpower and material resources.Wearing and tearing generally all occur in surface of the work, improving the surface of the work antiwear property by surface engineering technology at present is newer method, in these new technologies, in the application as thermospray, built-up welding, thermo-chemical treatment, vapour deposition, plating etc., the selection that Wear-resistant contains gold copper-base alloy is the key of technology success.Chang Yong alloy exists different separately shortcomings in the market: (1) nickel-base alloy has higher hardness and toughness preferably, and wear resistant friction reducing performance is preferably arranged in mud, clear water, stability might as well, but bead-welding technology complexity, surface crack is many; (2) copper base alloy has lower hardness, is HB130 only, extraordinary plasticity and toughness are arranged, but self wears no resistance; (3) cobalt base alloy has good wear resistant friction reducing performance, but cost is too high, and general industry is difficult to accept; (4) ferrous alloy has wear resistant friction reducing performance preferably, and its prices of raw and semifnished materials are also the most cheap, but self wear resistance is poor slightly.By as can be seen above, lack the high powdered alloy of a kind of over-all properties in the market.
Summary of the invention:
The present invention will overcome the shortcoming of prior art over-all properties difference.
For overcoming the shortcoming of prior art, technical solution of the present invention is: a kind of surfacing powdered alloy, its special character are that it is mixed by following material in parts by weight, 18～30 parts of Cr; 4～9 parts of Ni; 2～6 parts of Mn; 2～6 parts of Si; 2～4.5 parts of 2～5 parts of B: C.
Such scheme is mixed by following material in parts by weight, 27～28 parts of Cr; 7～8 parts of Ni; 3～5 parts of Mn; 3～4 parts of Si; 3.5～3.6 parts of B; 3～4 parts of C, the wear resistant friction reducing effect of this preferred version is better.
Compared with prior art, advantage of the present invention is to have better comprehensive performance, and this is embodied in the following aspects:
1, resistance to abrasion and antifriction quality coupling rationally: the present invention considers from the basic demand of alloy wear-resisting anti-attrition, follow " balance wearing and tearing design " notion and " stability " principle, balance wearing and tearing design " notion is meant under the prerequisite minimum to component wear; and self wearing and tearing is also little; or in the wear range that allows; " stability " no matter principle is meant good alloy under clear water or different mud condition, and it is relative stable that its antiwear property should keep, and should not change with condition to occur than big-difference.The present invention has the advantages that wear rate is low, frictional coefficient is low under clear water or different mud condition, therefore have good performance; When forming fastness with medium carbon steel in mud, the coating resistance to abrasion surpasses similar products at home and abroad; And the wearing and tearing of mating plate are compared with similar products at home and abroad, and small size raising is also arranged;
2, have favorable manufacturability: powder of the present invention is behind surfacing, and its tissue is tiny pebbles air quenching martensitic structure, and bead-welding technology (wettability, levelling property, deslagging, venting quality) is good; And powder surfacing rear surface is smoothly even, and crackle is few, does not have the piece that comes off, and therefore both can be used for manual surfacing, can be used for plasma spray again;
3, have resistance to abrasion preferably: because Cr, Ni, B, alloy adding such as C are bigger, and hard metal compound quantity is many, the hardness height, self resistance to abrasion is fine;
4, the present invention is applied widely, can be used for oil drill rocker, sucker rod and some other needs are wear-resisting and the surface abrasion resistance of the metallic magnetism spare of anti-attrition is strengthened.
Embodiment:
Below will the invention will be further described by several preferred embodiments, but the present invention is not limited in the content of described embodiment.
