Abstract

The present invention discloses a copper-base low-voltage electric contact material coated by diamonds and oxides and a production method thereof, which is characterized in that a copper alloy is used as a basal material; accordingly, an electrical contact has high electric conductivity, high thermal conductivity and favorable anti-oxidation performance; the electrical contact for low-voltage electric appliances has the advantages of strong breaking capacity, high resistance capability of arc burning and fusion welding and high electrical durability. The copper-base low-voltage electric contact material is prepared by that diamond micropowder of which the particle size is from 5 nm to 200 nm and nanometer-grade micropowder of stannic oxide and antimony oxide are added into a basal body of the oxidation-resistant copper alloy, the content of the diamond micropowder is from 0.1 to 5 wt%, the content of the stannic oxide is from 0.1 to 10 wt%, the content of the antimony oxide is from 0.1 to 10 wt%, and the rest is copper power.

Description

Copper base coated by diamond coated by oxide is low-voltage electrical contact material and production method
The invention belongs to a kind of copper base alloy, the contact alloy material of a kind of special applications in low-voltage apparatus.
The copper-based electrical contact alloy material discloses a plurality of technical schemes in Chinese patent, the novel electrician's contact of this copper-based non-silver is the novel novel material that is applied in the low-voltage apparatus.Its feature is to have stronger breaking capacity, anti-electrical arc erosion ability and anti-melting welding ability.But when copper-based non-silver electric contact was applied on the low-voltage apparatuses such as alternating current contactor, electric life was lower than traditional silver alloys electrical contact.
The present invention seeks to disclose a kind of copper base coated by diamond coated by oxide is the low-voltage electrical contact material, discloses its production method simultaneously.The novel copper-based non-silver electric contact material of the present invention, its copper alloy is a body material, can make electrical contact have very high electric conductivity thermal conductivity and good oxidization resistance energy.The electrical contact that is used for low-voltage apparatus except that having stronger breaking capacity, outside anti-electrical arc erosion ability and the anti-melting welding ability, also has very high electric life.
The present invention is a kind of powder metallurgy of copper, its composition is to add particle size at 5-200nm diadust and nano level tindioxide, weisspiessglanz micro mist in the matrix of resistance to oxidation copper alloy, the content of diadust is at 0.1-5% (wt), the content of tindioxide the content of 0.1-10% (wt), weisspiessglanz at 0.1-10% (wt), all the other are copper powder.
Production method of the present invention is:
(1), make copper/silver evenly be coated on the surface of diadust with Nano diamond micro mist electroless plating.The diadust particle size is at 5-200nm, and coating bed thickness is 5nm-1 μ m;
(2) with nano level tindioxide (SnO2) and weisspiessglanz (Sb2O3) micro mist electroless copper/silver, copper/silver evenly is coated on the surface of tindioxide and antimony oxide particle.Tindioxide (SnO2) and weisspiessglanz (Sb2O3) micro powder granule size are at 5-200nm, and coating bed thickness is 5nm-1 μ m;
(3) Nano diamond micro mist and tindioxide weisspiessglanz micro mist and the prealloy copper powder uniform mixing after will coating.
(4) cold isostatic compaction under the pressure of 200Mpa-250Mpa.
(5) blank after the moulding is under the vacuum less than 10Mpa, at 850--950 ℃ of following sintering 1-1.5 hour.
(6) blank behind the sintering is at 700--750 ℃ of following hot extrusion molding.
(7) section bar after the hot extrusion is cut into the shape that contact requires.
The present invention has very high electric life.Add diadust in copper alloy matrix, diamond particles coats copper or silver with electroless plating method.In electrical contact material, play anti-electrical arc erosion and anti-melting welding effect.Tindioxide and antimony oxide particle play the effect of arc extinguishing and anti-melting welding in electrical contact.Arc extinguishing and anti-melting welding do not contain the oxide compound carcinogens of cadmium metal commonly used and cadmium, satisfy in the low-voltage apparatus the every technical requirements to electrical contact fully.Its method is to be suitable for industrialization technology.
