Description

本发明属于银基合金电接触材料。 The present invention is in electrical contact with the silver-based alloy material.

银基合金被广泛用作电接触材料。 Silver-based alloy is widely used as an electrical contact material. 传统的银基电接触材料包括有:纯银、Ag-CdO、Ag-Ni、等等,而其中运用范围较宽的是Ag-CdO,近年来,为了适应新的技术要求,降低材料成本,消除镉的毒害,传统的银基电接触材料得到了改进,并发展了Ag-SnO2系、Ag-Bi2O3系以及银-稀土金属氧化物系等新的银基电接触材料。 Traditional silver based electrical contact material comprising: silver, Ag-CdO, Ag-Ni, etc., wherein the operating range is wide Ag-CdO, in recent years, in order to meet the new technical requirements, reduce material costs, detoxified cadmium, conventional silver-based electrical contact material has been improved, and the development of Ag-SnO2-based, Ag-Bi2O3-based and the silver - novel silver based electrical contact material, a rare earth metal oxide and the like. 日本《工业材料》(Vol,NO3.1979.P15)报道了Ag中添加Ce族(La、Ce、Pr、Lu)及Mg、Mn、Zn、Ti、Ni、Zr中至少一种金属元素进行内氧化制备的银-稀土金属氧化物电接触材料,其性能在某些条下与AgCdO相当,特别适用于中小电流的继电器。 Japan, "Industrial Material" (Vol, NO3.1979.P15) Ag reported in the group of Ce (La, Ce, Pr, Lu) and Mg, Mn, Zn, Ti, Ni, Zr, at least one metal element for the preparation of silver oxide - rare earth metal oxide electrical contact material, its performance under certain conditions and AgCdO considerable, especially for small current relay. 为了提高小型整流器接点片Ag-Cd,Ag-Cu、Ag-Sn合金的耐磨性,JP58-107445公开了在Ag中添加Sn、W、Ce、Sb、Cd、Mo、Se、Zn、Ca、Mg以及Fe族元素制备的接点材料;JP58-107452公开了在Ag中添加Cu、Si、Zr、Bi、Ga以及Fe族元素的接点材料:JP61-130442公开了在Ag中添加C、B、Si、Ge、Te以及Fe族元素的接点材料;JP61-130444公开了在Ag中添加C、In、Sn以及Fe族元素的接点材料:JP61-130445公开了在Ag中添加C、Al、Ga、Mn以及Fe族元素的接点材料;JP61-130447公开了一种在Ag中添加C、Cr、Mg、Zr以及Fe族元素的接点材料。 In order to increase the contact sheet compact rectifier Ag-Cd, Ag-Cu, Ag-Sn alloy in the wear resistance, JP58-107445 discloses a method of adding Ag, Sn, W, Ce, Sb, Cd, Mo, Se, Zn, Ca, Mg and Fe contact material prepared elements; JP58-107452 discloses adding contact material Cu, Si, Zr, Bi, Ga and Fe group elements in Ag: JP61-130442 discloses the addition of C, B in Ag, Si , Ge, Te and Fe group element contact material; JP61-130444 discloses a contact material is added C, in, Sn and Fe group elements in Ag: JP61-130445 discloses the addition of C, Al to Ag, Ga, Mn and a contact material Fe group element; JP61-130447 disclose a C in Ag contact materials Cr, Mg, Zr, and Fe group elements. 这些材料的耐磨性都有较大提高,但接触电阻都比较大。 The wear resistance of these materials have greatly improved, but the relatively large contact resistance.

随着继电器的微型化,接触力、断开力、接电间隙减小,要求电接触材料有低而稳定的接触电阻、温升小,有更好的灭弧性、抗熔焊性,耐电损耗,抗粘接,抗金属转移等。 With the miniaturization, the contact force, the relay opening force, electrical connection gap is reduced, the electrical contact material requires low and stable contact resistance, low temperature rise, a better arc-extinguishing, welding resistance, resistance to power loss, anti-adhesion, anti-metal transfer. 上述银基电接触材料用于微型继电器上都存在一定的问题。 The silver based electrical contact material used there are some problems on the micro-relay. 在220V,10A,接触力6g,通断频率30次分的微继电器上,性能较好的Ag-CdO的电寿命不到3万次,达不到10万次的电寿命设计要求。 In 220V, 10A, the contact force 6g, the micro relay-off frequency of 30 minutes, better performance of the electrical life of Ag-CdO is less than 30,000, up to 100,000 times less than the life of the electrical design requirements. 其他银基电接触材料不是因为接触电阻高,就是因为电寿命短而用不上。 Other silver based electrical contact material is not because of high contact resistance is irrelevant because of the short lifetime electrically. 此外,上述电接触材料除少数合金外,都是粉末冶金或内氧化生产,工艺复杂,加工性能差,成本高,Ag-CdO还造成公害,而且Ag-CdO不易焊接。 Further, the electrical contact alloy material except for a few, are all within the complex oxidation or powder metallurgy production process, poor processability, high cost, also caused by pollution Ag-CdO, Ag-CdO and easy welding.

本发明提出一种新的银基合金电接触材料。 The present invention provides a novel silver based alloy electrical contact materials. 这种材料接触电阻低而稳定,灭弧性、抗熔焊性、抗粘接性、抗烧损性、耐磨性、抗电蚀性以及加工性能好。 This material is low and stable contact resistance, arc extinguishing property, welding resistance, anti-caking resistance, burning resistance, abrasion resistance, electrical corrosion resistance and good processability. 这种材料不仅能用于微型继电器上,而且在中小电流的交直流继电器上可部分代替Ag-CdO及其他一些银基电接触材料。 This material not only for the micro-relay, the relay but also in the small DC current may partially replace Ag-CdO and other silver based electrical contact material.

本发明提出的银基合金材料的组成(wt%)为:1.稀土元素Sm、Yb、Eu、Tm、Ho、Dy、Er中至少一种元素,含量为0.05~2,最佳为0.5~1.5;Fe、Co、Ni、W、V、Cr、Zr、B、C、Si中至少一种元素,含量为0.005~0.5,最佳为0.05~0.3;Sn、Al、Cu、Zn、Ga、Ge、In、Mn、Bi、Mg中至少一种元素,含量为0.1~5,最佳为0.3~2;余量为银。 Composition of the silver-based alloy material of the present invention proposed (wt%) of: 1 rare earth element Sm, Yb, Eu, Tm, Ho, Dy, Er at least one element in an amount of 0.05 to 2, most preferably 0.5 to 1.5; Fe, Co, Ni, W, V, Cr, Zr, B, C, Si, at least one element in an amount of 0.005 to 0.5, most preferably 0.05 ~ 0.3; Sn, Al, Cu, Zn, Ga, Ge, in, Mn, Bi, Mg, at least one element in an amount of 0.1 to 5, most preferably 0.3 to 2; the balance being silver.

银由于具有金属中最高的导电性和导热性,极好的加工性能,所以银或银合金被广泛用作电接触材料。 Because silver metal highest thermal conductivity and electrical conductivity, excellent processability, the silver or silver alloy is widely used as an electrical contact material. 稀土元素Sm、Yb、Eu、Tm、Ho、Dy、Er以及La、Ce、Y、Gd、Pr、Nd、Lu能够强有力细化银的晶粒组织和提高银再结晶温度,同时它们的蒸气压都较高,易挥发,尤其是Sm、Yb、Eu、Tm等的蒸气压比其他稀土元素更高,更容易挥发,在接点起弧时,蒸发出来的大量稀土元素的蒸气可以迅速灭弧,降低温升,从而大大提高接点的灭弧性能和抗电蚀性能。 Rare earth element Sm, Yb, Eu, Tm, Ho, Dy, Er and La, Ce, Y, Gd, Pr, Nd, Lu can be strongly refined grain structure and improved silver silver recrystallization temperature, while vapor thereof have a high pressure, volatile, especially Sm, Yb, Eu, Tm and other higher vapor pressure than the other rare earth elements, more volatile, when the arcing contacts, the vapor evaporated rapidly quenching a large amount of rare earth elements , reduce temperature, thereby greatly improving the arc extinguishing property corrosion resistance and electrical contacts. 电弧的迅速熄灭使熔化的银很快凝固,避免了熔焊,本发明的银基合金不进行内氧化处理,从而避免了稀土元素以氧化物形式存在于银中,而由于稀土氧化物熔点很高。 And extinguish the arc rapidly solidified molten silver, welding is avoided, silver-based alloy of the present invention, the oxidation treatment is not carried out, thereby avoiding the rare earth element is present in the form of silver oxide, and the melting point is due to the rare earth oxide high. 蒸气压低,在燃弧过程中起不到灭弧作用而有可能使电弧重燃的问题。 Low vapor pressure in the arc extinguishing process would not achieve the role likely to make the problem of reignition. 但稀土元素少于0.05Wt%时作用不大,大于2.Wt%时难于加工Fe、Co、Ni、W、V、Cr、Zr、Si及B、C的加入有利于进一步细化晶粒,提高微观硬度,提高合金耐磨性,抗粘接性,抗熔焊性,加入量少于0.005wt%时作用不大,而大于0.5wt%时,要用粉末冶金方法加工,而且合金的接触电阻会增高。 But little effect of rare earth elements is less than 0.05 wt%, Fe are difficult to process greater than 2.Wt%, Co, Ni, W, V, Cr, Zr, Si, and B, C is added to further facilitate grain refinement, micro-hardness increase, improve the alloy wear resistance, adhesion, welding resistance, added amount is less than 0.005wt% has little effect, while greater than 0.5wt%, use of powder metallurgy processing, and contacting the alloy the resistance will increase. 选择的Sn、Al、Cu、Zn、Ga、Ge、In、Mn、Bi、Mg元素是一些低熔点的金属,它们能与Ag形成合金,又能与Fe、Co、Ni、W、V、Cr、Zr、Si及B、C形成熔点较低的中间合金,可以均匀地把不能与Ag互溶的金属和非金属(Fe、Co、Ni、W、V、Cr、Zr、Si及B、C)添加到银中,改善材料的性能,另一方面,它们还具有一定的抗硫化性,可以降低材料的接触电阻和使其稳定,但加入量少于0.1wt%时作用不大,而大于5wt%时,又会使接触电阻升高。 Selected Sn, Al, Cu, Zn, Ga, Ge, In, Mn, Bi, Mg elements are some of the low melting point metal which can be alloyed with Ag, but also with Fe, Co, Ni, W, V, Cr , Zr, Si, and B, C formed intermediate lower melting alloy can be uniformly and not the metal and non-miscible Ag (Fe, Co, Ni, W, V, Cr, Zr, Si, and B, C) added to the silver, to improve the properties of the material, on the other hand, they also have some anti-sulfurization resistance, the contact resistance can be reduced and stabilized material, but less than 0.1wt% is added little effect whereas more than 5wt %, the contact resistance will increase further.

本发明的合金具有以下的优点:1、灭弧性、抗熔焊性、抗损耗、抗粘接性以及抗金属转移性好,接触电阻低而且稳定,温升小,在微型继电器(220V、10A、接触力6g、通断频率30次/分)上通过全性能试验,达到电寿命为10万次的设计要求。 Alloy of the invention has the following advantages: 1, the arc extinguishing property, welding resistance, resistance to loss, anti-adhesion and anti-metastatic good metal, the contact resistance low and stable, small temperature rise in the micro-relay (220V, 1OA, the contact force 6g, switching frequency of 30 times / min) through the full performance test, reaches the level of 10 million times of life design requirements.

2、生产工艺简单,成本低,本发明的合金按常规熔炼方法,加工方法制成丝材或片材,不进行内氧化处理,加工过程中能耗低,劳动量小,故生产成本低,生产技术工艺具有明显经济效益。 2, the production process is simple, low cost, the alloy of the present invention, a conventional smelting process, the processing method is made of wire or sheet, without performing the oxidation treatment process is low energy consumption, a small amount of labor, so that the production cost is low, production technology has obvious economic benefits.
