Description
Technical field
The present invention relates to a kind of polynary Benedict metal of corrosion-proof wear and its preparation and processing method, belong to non-ferrous metal and add
Work field.
Background technology
Copper alloy has good conduction, heat conduction and heat dispersion because of it, has obtained widely as functional material
Application, but the continuous development with market segment, just progressively extend the application of copper-based alloy material, such as anti-corrosion, wear-resisting or
False proof alloy material, the application especially as corrosion and wear resistant alloy material just progressively highlights, and has just like become Copper base material
Expect new market segment.
In recent years, China sea transport, marine resources using and the aspect such as bank, offshore engineering construction achieve
Huge progress, associated ocean engineering material industry serves the supporting role of key.It is related to naval vessel, ocean platform, oil
Gas pipeline and offshore building etc. field use non-ferrous metal and its composite, home products still based on traditional product,
Technology content is low, and added value is low, still in low-end market, high performance material still a large amount of dependence on import；Simultaneously with toward ocean
Development of resources from the close-by examples to those far off, from the superficial to the deep progressively deeply, the Work tool of ocean operation is put forward higher requirement, especially
To the ship part matching with this, the combination property of the cuprio parts such as steam and water pipe is put forward higher requirement.Cause
The basic material research and development that this accelerates ocean engineering resistant material will have very important significance.
HNi65-5 alloy, as anti-corrosive copper based alloy, is usually used in making ship part, the cuprio such as steam and water pipe zero
Part, and in HNi65-5 alloy, " zinc " equivalent coefficient is 25.7%, its Zn content is still higher, causes its anti-Dezincification corrosion and stress
Corrosive power is still weaker, therefore alloy characteristic can only meet shallow sea field；In addition its wear-resistant property low it is difficult to meet further
Use demand, but march towards deep-sea direction with ocean development, corrosion-resistant and wear-resistant property are proposed harsher
Require, thus the growth requirement to meet marine engineering equipment for the new corrosion-proof wear copper-based alloy material need to be researched and developed.
Content of the invention
The main object of the present invention is the deficiency making up in existing copper alloy combination property, in the base of conventional Benedict metal
On plinth, keep reducing Zn content while Ni content is constant, and add the alloying elements such as a small amount of Al, Mn and by Co, B and In
Three kinds of elementary composition composite modifiers, improve to alloying component and internal organizational structure, put forward heavy alloyed combination property,
It is desirably to obtain a kind of polynary Benedict metal of corrosion-proof wear.
In order to achieve the above object, the present invention is realized in：
A kind of polynary Benedict metal of corrosion-proof wear, it contains the chemical composition of following percetage by weight：Cu 74.0～
76.0, Ni 4.75～5.25%, Al 0.2～0.4%, Mn 0.6～0.9%, remaining is Zn.
Further, this alloy also contains B, Co and In, and percetage by weight is respectively B 0.005～0.01%, Co
0.012～0.05%, In 0.003～0.01%, total content 0.02～0.06%.
The effect of institute's addition element：
Nickel and copper form continuous solid solution, and its zinc equivalent is negative value it will be apparent that expanding alpha phase zone, improve alloy in air and
Corrosion resistance in sea water, plays Stabilization to dezincification and stress corrosion.Nickel element can also crystal grain thinning, improve alloy strength.
In addition the addition of nickel element can also carry heavy alloyed heat resisting temperature.For avoiding being excessively used of precious metal element, in brass alloys
Content≤6% of nickel element, preferably 4.75～5.25%.
The zinc equivalent of aluminum is very high, adds aluminium element can be reduced significantly alpha phase zone, put forward heavy alloyed intensity.Aluminum is in alloy surface
Ionization tendency bigger than zinc, can the preferential sull that be combined generation hard and compact with the oxygen in corrosive medium, thus carrying
High brass alloys corrosion resistance in the seawater, simultaneously nickel aluminum form a kind of high-strength wearable phase, effectively improve material circulation plasticity
Resistance of deformation is so that the antiwear characteristic of alloy material is improved.In pyrite, the aluminum of excessive addition can make tissue thick, typically
Aluminium content 1%, the content of therefore preferably aluminum is 0.2～0.4%.
Manganese can be solid-solution in cuprio in a large number, plays the effect of solution strengthening, and manganese element can significantly improve pyrite in sea
Corrosion resistance in water, chloride and superheated steam, manganese element itself as reinforced wear-resistant phase simultaneously, especially with boron, cobalt, indium unit
The collective effect of element, forms a kind of wear-resistant particle so that the wear-resistant property of material is significantly improved.
Boron, indium, the addition of cobalt element can put forward heavy alloyed intensity, hardness and plasticity with crystal grain thinning, but Boron contents >=
When 0.1%, material plasticity declines, and the interpolation of indium and cobalt all can make alloy have special metallic luster, three kinds of elements common
Addition can effectively improve anti-Dezincification corrosion and the stress corrosion characteristics of alloy, makes material have a good decay resistance, and three
The collective effect planting element is better than interpolation one of which or two kinds of elements.
