Abstract
A palladium-base alloy as contact material consists of Pd 30-85 wt%, Cu 14-70 wt% and RE (one of La, Ce, Sm and Gd) 0.05-1 wt%. Palladium-base composite contactor is prepared by compounding the palladium-base alloy of the present invention and copper alloy-base material, which comprises Cu 84-98.4 wt%, Fe 0.5-5 wt%, Ag 1-10 wt% and RE (one of La, CE, Sm and Gd) 0.1-10 wt%. The alloy material of the present invention is prepared through conventional casting and heat treatment process. the palladium-base alloy may be produced into wire, belt, pure alloy contact or composite alloy contact as required.
Description
The present invention relates to the alloy contact material, particularly the multiple copper contact material of palladium-base alloy contact material and palladium base.
Electronics, instrument serviceability, closely related with employed contact material to a great extent.Ag base alloy is usually used in the various device for switching owing to its good electrical properties, but under DC condition, the anti-metal transfer poor performance of Ag base alloy is in use often found the metal transfer phenomenon, causes contact adhesion, ultimate failure, thus the reliability and the life-span of electrical equipment influenced.Be used in the multiple Ag base alloy such as the AgNi10 of 11E953227D car photoflash lamp rly. at present, Ag (CdO) 12 etc. under the nominal loading condition, the bonding situation often occurs, badly influence the use of rly..
Along with China's car industrial expansion, the raising of car class develops with rly. trend high reliability long life car, and use has highly reliable contact material and seems particularly important and necessary.Therefore, often select for use the PdCu15 alloy to replace the contact material of Ag base alloy, but the PdCu15 alloy have certain difficulty, and is difficult to make composite contact with the Cu base in the production because Pd is easily air-breathing as rly..
The objective of the invention is to overcome difficulty in the contact material productions such as having the PdCu15 alloy now and the deficiency that is difficult to produce composite contact, it is better to have proposed a kind of over-all properties, can on the conventional rivets machine, produce the Pd base alloy of composite contact, a kind of copper alloy that is suitable as the composite contact base material is proposed simultaneously, by technical study, realized producing on the common homemade composite rivet machine the multiple copper contact of PdCu rare earth alloy.
Technical scheme of the present invention realizes by following steps:
First part: palladium-base alloy contact material
In the PdCu alloy, add an amount of rare earth elements RE (RE=La, Ce, Sm, a kind of in Gd) to form new PdCuRE alloy.The concrete composition (weight %) of this alloy is: Pd30～85, and Cu 14～70, and RE 0.05～1.
The PdCu alloy has superior anti-direct current transfer characteristics, anti-melting welding is good, can bear bigger rush of current, adding rare earth element can the refinement alloy grain and improve recrystallization temperature, thereby improve the stability of material, improve the casting quality of PdCu alloy, eliminate the cavity of the multiple copper contact compound interface of PdCu alloy, improve the contact combined strength bination, make it the multiple copper contact of PdCuRE alloy that the quality of production is qualified on homemade composite rivet machine.
Second partly: composite contact base material copper alloy
In copper, add small amount of Fe, Ag and rare earth RE (RE=La, Ce, Sm, a kind of in Gd) to form a kind of new copper alloy.The concrete composition (weight %) of this Albatra metal-is Cu84～98.4, Fe0.5～5, Ag1～10, rare earth (RE) 0.1～1.
Add Fe among the Cu, the Ag element forms common solution with Cu, makes the intensity of Cu, and hardness improves.Add trace rare-earth element and rise the strengthening effect, can also play effects such as purification, deoxidation, add Fe except being partially soluble in Cu, the Ag rare earth element, less to the electroconductibility influence of Cu.Utilize this Cu alloy and PdCuRE alloy material of the present invention, can on homemade composite rivet machine, produce composite contact.
Palladium-base alloy contact material of the present invention can use separately, also can be compounded to form composite contact with copper alloy of the present invention and use.The advantage of composite contact is: (1) saves the palladium material; (2) the common composite rivet machine of available home-made is produced.
Palladium-base alloy of the present invention and copper alloy base material adopt conventional founding, processing, heat treating method preparation.Palladium-base alloy can be processed into a material as required, the isozygoty golden contact and the composite contact of band and all size.The Fu Tai contact can produce on the conventional rivets machine.
Embodiment:
1, adopt purity 99.95%Pd, Cu RE presses the composition alloyage of table 1, and with the founding under protective atmosphere of high-quality crucible, processing of alloy working method and thermal treatment with traditional are prepared into 1.9mm silk among the φ:
2, be 99.95%Cu, Ag with purity, rare earth, the Fe of purity 99.9% are pressed the composition alloyage of table 2, make φ 1.9mm silk with traditional method equally:
3, adopt palladium-base alloy and the copper alloy silk material of φ 1.9mm, produce φ 3 * 0.8/ φ 2 * 0.9mm composite contact on homemade composite rivet machine, the contact is assemblied in after the polished finish in the 11E9532722D rly. through thermal treatment.Table 1 palladium-base alloy material mixture ratio (weight %)
