Description
Technical field
The present invention relates to a kind of metal that is not subjected to mechanical wear.
Background technology
The metal of metallicity meets the ability of each generic request, so as to the characteristic of characterizing metal.It depends on composition, structure and the tissue of metal.Mainly contain mechanical property, physical property, chemical property and processing performance etc.Mechanical property relates to the performance of stress and strain relation under the power effect.According to the mechanical behavior of material, the mechanical performance index of exosyndrome material can be divided into elasticity, plasticity, intensity, hardness and toughness etc.The mechanical property of metal is the important evidence that evaluation metallic material, selection and member designs are calculated, and with corresponding mechanical test, measures.Physical property reflects under the physical actions such as power, heat, light, electricity characteristic.Commonly used have in-fighting, thermal coefficient of expansion, thermal conductivity factor, specific heat capacity and a resistivity etc.The mechanical vibrational energy of interior consumption material itself consumes gradually when mechanical oscillation phenomenon.The ratio of the variation of scantling and original size during 1 ℃ of thermal coefficient of expansion temperature rise. can be divided into linear expansion coefficient and the coefficient of volume expansion.When on thermal conductivity factor material unit length, temperature difference is IC, interior heat flow by unit are of unit interval.The size of its numerical value, depend on material internal structure and status.Simple metal has higher thermal conductivity factor than alloy.Needed heat energy during 1 ℃ of specific heat capacity unit mass material temperature rise.The resistance of resistivity unit cross-sectional area material on unit length.The ability of chemical property opposing Korrosionsmedium chemical erosion effect.Corrosion of metal can be divided into two kinds of chemical attack and electrochemical corrosion.The oxidation of metal is in fact the result of chemical attack.The metallochemistry corrosion rate is relevant with the character of the metal surface film that is formed by corrosion product.Electrochemical corrosion depends primarily on the electrode potential of metal.The essential measure that improves corrosion resistance and non-oxidizability is the alloying of material.Cause metal to lack high temperature service life, mechanical wear and electricity, thermal conductivity.
Summary of the invention
The object of the present invention is to provide a kind of metal that is not subjected to mechanical wear with high temperature resistant life-span length, anti-mechanical wear and electricity, the good effect of thermal conductivity.
Technical scheme of the present invention is: a kind of metal that is not subjected to mechanical wear, comprise hard alloy layer, elastic alloy layer and expansion alloy layer, described hard alloy layer is tungsten carbide, described elastic alloy layer is tin-phosphor bronze, described expansion alloy layer is the nickel chromium triangle alfer, each composition weight proportion is that tungsten carbide accounts for 20%-37%, and tin-phosphor bronze accounts for 38%-41%, and the nickel chromium triangle alfer accounts for 24%-40%.

In a preferred embodiment of the present invention, described not to be subjected to each composition weight proportion of metal of mechanical wear be that tungsten carbide accounts for 31%, and tin-phosphor bronze accounts for 39%, and the nickel chromium triangle alfer accounts for 30%.
A kind of metal that is not subjected to mechanical wear of the present invention, have long, anti-mechanical wear of high temperature resistant life-span and electricity, effect that thermal conductivity is good.
The specific embodiment
Below in conjunction with preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
In one embodiment, a kind of metal that is not subjected to mechanical wear, comprise hard alloy layer, elastic alloy layer and expansion alloy layer, described hard alloy layer is tungsten carbide, and described elastic alloy layer is tin-phosphor bronze, and described expansion alloy layer is the nickel chromium triangle alfer, each composition weight proportion is that tungsten carbide accounts for 20%-37%, tin-phosphor bronze accounts for 38%-41%, and the nickel chromium triangle alfer accounts for 24%-40%, and described nickel chromium triangle alfer comprises nickel, chromium, aluminium and iron.
Further illustrate, described not to be subjected to each composition weight proportion of metal of mechanical wear be that tungsten carbide accounts for 31%, and tin-phosphor bronze accounts for 39%, and the nickel chromium triangle alfer accounts for 30%.
Can debug according to different proportion according to different demands, thereby reach different results of use, tungsten carbide is the primary raw material of producing carbide alloy, for the black hexagonal, metallic luster is arranged, and hardness and diamond are close, is electric, hot good conductor.Tungsten carbide is water insoluble, hydrochloric acid and sulfuric acid, is soluble in the mixed acid of nitrate acid and hydrofluoric acid.Pure tungsten carbide is frangible,, if mix the metals such as a small amount of titanium, cobalt, just can reduce fragility.Tungsten carbide as the steel cutting tool, often add titanium carbide, ramet or their mixture, to improve the antiknock ability.The stable chemical nature of tungsten carbide
Further illustrating, tin-phosphor bronze has higher corrosion resistance, and is wear-resistant, flashing not while going out.Be used for, middling speed, heavy load have bearing, 250 ℃ of work maximum temperatures.Have automatic aligning insensitive to deflection, the even bearing capacity of shaft strength is high, can be subjected to simultaneously the characteristics such as radial load, self-lubricating Maintenance free.
Further illustrating, the nickel chromium triangle alfer is precision electrical resistance alloy, usually can divide precision resistor with electric resistance alloy, rheostat with electric resistance alloy and heater electric resistance alloy.Precision resistor is lower with the heating temperature of electric resistance alloy, generally at room temperature uses, as copper-manganese, Nimonic etc.; Rheostat generally is no more than 500 ℃ with the heating temperature of electric resistance alloy, as ambrose alloy, constantan etc.; Heater can reach 1400 ℃ with the heating temp of electric resistance alloy, as Aludirome, nichrome etc.The invention provides a kind of metal that is not subjected to mechanical wear, have long, anti-mechanical wear of high temperature resistant life-span and electricity, effect that thermal conductivity is good.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
