中國(guó)合金企業(yè)——周口環(huán)宇金屬科技有限公司
周口環(huán)宇生產(chǎn)多種規(guī)格巴氏合金、軸承合金、錫基合金、鋁合金、鋅合金、軸瓦、軸套、模塊、滑塊、墊塊、配重塊，廣泛應(yīng)用于各種機(jī)械軸瓦、軸承、軸套，密封耐磨、耐腐蝕、抗震耐壓。機(jī)械軸瓦軸套類有球磨機(jī)、減速機(jī)、電機(jī)、風(fēng)機(jī)、汽輪機(jī)、水輪機(jī)、蒸汽機(jī)、內(nèi)燃機(jī)、柴油機(jī)、汽油機(jī)、壓縮機(jī)、破碎機(jī)、造紙機(jī)、軋鋼機(jī)、制管機(jī)、化工機(jī)械、石油機(jī)械、礦山機(jī)械、船舶機(jī)械、機(jī)床、機(jī)車等。
按國(guó)家標(biāo)準(zhǔn)，巴氏合金可以分為錫基合金和鉛基合金兩種。鉛基合金的強(qiáng)度和硬度比錫基合金低，耐蝕性也差。所以客戶在使用巴氏合金的時(shí)候，通常選用錫基合金，其常用的牌號(hào)有zchsnsb11-6、zchsnsb8-4、zchsnsb8-8等。盡管鉛基合金的性能沒有錫基合金好，但是有許多客戶仍然選擇使用，因?yàn)樗褂闷饋肀容^經(jīng)濟(jì)，其常用的牌號(hào)有zchpbsb16-16-2、zchpbsb1-16-1等。
巴氏合金的主要合金成分是錫、鉛、銻、銅。銻、銅，用以提高合金強(qiáng)度和硬度。巴氏合金的組織特點(diǎn)是，在軟相基體上均勻分布著硬相質(zhì)點(diǎn)，軟相基體使合金具有非常好的嵌藏性、順應(yīng)性和抗咬合性，并在磨合后，軟基體內(nèi)凹，硬質(zhì)點(diǎn)外凸，使滑動(dòng)面之間形成微小間隙，成為貯油空間和潤(rùn)滑油通道，利于減摩;上凸的硬質(zhì)點(diǎn)起支承作用，有利于承載。
巴氏合金除制造滑動(dòng)軸承外，因其質(zhì)地軟、強(qiáng)度低，常將其絲或粉噴涂在鋼等基體上制成軸瓦使用。巴氏合金分錫基（見錫合金）和鉛基合金兩種。后者含銻10%～20%，錫5 %～15%，為防止成分偏析和細(xì)化晶粒，還常加入少量的砷。鉛基合金的強(qiáng)度和硬度比錫基合金低，耐蝕性也差。

the alloyleading brand - the zhoukou universal metal technology co., ltd.
zhoukouuniversal production of a variety of babbitt bearing alloy, tin-based alloys,aluminum, zinc alloy, bearings, bushings, module, slider pad with weights,widely used in various mechanical bearing, bearings, bushings, sealwear-resistant, corrosion-resistant, the seismic withstand voltage. mechanicalbearing bushings, ball mill, reducer, motor, fan, turbine, turbine, steamengine, internal combustion engines, diesel engines, gasoline engines,compressors, crushers, paper machines, rolling mills, tube making machine,chemical machinery, petroleum machinery, mining machinery, ship machinery,machine tools, locomotives.
according tonational standards, babbitt can be divided into two kinds of tin-based alloysand lead-based alloys. the strength and hardness of the lead-based alloy islower than tin-alloy, corrosion resistance is also poor. babbitt, so thecustomer is usually used tin-based alloys, commonly used grades arezchsnsb11-6, zchsnsb8-4, zchsnsb8-8, etc.. although the performance oflead-based alloy tin-based alloys, but many customers still choose to use,because it uses up more economical, their usual grades zchpbsb16-16-2, zchpbsb1-16-1.
babbitt alloycomposition is tin, lead, antimony, copper. antimony, copper, in order toincrease the strength of the alloy and hardness. babbitt organizationalcharacteristics of the hard phase particles uniformly distributed in the softphase matrix, the soft phase matrix alloy has a very good embedded withcompliance and anti-bite, and after the break, the soft matrix concave, hardspots convex, so that a small gap between the sliding surfaces, oil storagespace and lubricants channel, will help reduce friction; convex hard particlesfrom the supporting role, is conducive to carrying.
babbitt inaddition to the manufacture of plain bearings, because of its soft texture, lowintensity, often to wire or powder coating made ofbearing used in the steel matrix. babbitt tin-based （see tin alloy） and twolead-based alloys. the latter containing antimony 10% to 20%, 5% to 15% of tin,in order to prevent the composition segregation and grain refinement, but alsooften by adding a small amount of arsenic. the strength and hardness of thelead-based alloy is lower than tin-alloy, corrosion resistance is also poor.
