(4) embodiment
Below the invention will be further described.
A kind of Ag/Ti3SiC2 contact material of the present invention is to be 0.01～80.0% Ti3SiC2 powder by fine silver powder or silver-base alloy powder and weight percent, by the preparation of powder metallurgical technique method.
Ti3SiC2 belongs to hexagonal crystallographic texture, and the Si layer that the TiC octahedron of common rib is formed by the Si atom is separated, and forms special nanoscale layer sheet structure.This structure is given its image-stone China ink and is equally had oilness and workability, combines many premium propertiess of metal and pottery.The Ti3SiC2 fusing point has fabulous electroconductibility, thermal conductivity up to 3000 ℃, and its electroconductibility and pure metal are suitable, and electric conductivity reaches 4.7 * 10 in the time of 25 ℃
6Sm
-1, thermal conductivity reaches 33.5Wm
-1K
-1In addition, the high strength that Ti3SiC2 possessed, anti-thermal shock, corrosion-resistant, anti-oxidant, especially high temperature oxidation resistance and anti-cyclic oxidation ability and characteristics such as self lubricity and ultralow coefficient of friction, the needed key characteristic of contact material especially.
Diamond is the highest material of occurring in nature thermal conductivity, and thermal conductivity reaches 138.16Wm
-1K
-1Have performances such as fusing point height (about 3700 ℃), hardness be big, wear-resistant simultaneously, adopt powder metallurgy process in copper, to add tiny diamond particles, not only can play dispersion-strengthened action, improve the effect of hardness and wear resistance, also the heat that electric arc is produced conducts to crane span structure, reduces the contact surface temperature.The diamond particles of what is more important contact surface is burnt when beating arc, does not produce the settling that causes resistance to increase in contact surface.
Adopt the silver based alloy electric contact material of Ti3SiC2 preparation, more can embody high-strength, characteristics such as height is led, high-ductility, self-lubricating.Adopt powder metallurgy process in silver-base alloy, to add the Ti3SiC2 powder, not only can play dispersion-strengthened action, very little to the material electric conductivity influence simultaneously.Can play good anti-melting welding, anti-electric-arc ablation, anti-oxidant particularly resistance to high temperature oxidation as high and low voltage electrical equipment with the contact use, improve wear resistance, improve contact resistance, reduce effects such as temperature rise, raising electric life.Simultaneously, the Ti3SiC2 particle is as the hard particle, and the easier oxide layer stripping that contact surface is formed comes off.Therefore, can significantly improve the electrical property of these silver-based contacts.
Because the Ti3SiC2 particle is bad with the wetting property of silver, be difficult to form firm interface and combine with silver matrix, the Ti3SiC2 particle is difficult in the silver alloys and is evenly distributed, and reduces the effect of dispersion-strengthened, causes its excellent performance to be not in full use.Therefore earlier the Ti3SiC2 powder being carried out necessary coating handles---chemical silvering, and to solve wetting property and distribution problem.
Preparation technology is as follows for a kind of Ag/Ti3SiC2 contact material of the present invention:
(1), make silver evenly be coated on the surface of Ti3SiC2 powder with Ti3SiC2 powder chemical silvering under the ultrasonic wave effect.Coating thickness is 5nm～1000nm;
(2) Ti3SiC2 powder after will coating and fine silver powder or silver-base alloy powder mix under protective atmosphere;
(3) the mixed powder isostatic cool pressing under 250～300MPa that is obtained is become the right cylinder stock of diameter 50mm;
(4) the right cylinder stock under protective atmosphere in 800～950 ℃ of sintering 2～4h;
(5) stock behind the sintering is hot-pressed under 700～850 ℃, is referred to as extruded section;
(6) extruded section carries out ageing treatment under vacuum or protective atmosphere, 500～800 ℃ of treatment temps, 1～5 hour treatment time;
(7) will carry out mechanical workout by product size through after the section rolling of ageing treatment or the drawing processing.
