中国合金企业——周口环宇金属科技有限公司

　　周口环宇生产多种规格巴氏合金、轴承合金、锡基合金、铝合金、锌合金、轴瓦、轴套、模块、滑块、垫块、配重块，广泛应用于各种机械轴瓦、轴承、轴套，密封耐磨、耐腐蚀、抗震耐压。机械轴瓦轴套类有球磨机、减速机、电机、风机、汽轮机、水轮机、蒸汽机、内燃机、柴油机、汽油机、压缩机、破碎机、造纸机、轧钢机、制管机、化工机械、石油机械、矿山机械、船舶机械、机床、机车等。

　　按国家标准，巴氏合金可以分为锡基合金和铅基合金两种。铅基合金的强度和硬度比锡基合金低，耐蚀性也差。所以客户在使用巴氏合金的时候，通常选用锡基合金，其常用的牌号有zchsnsb11-6、zchsnsb8-4、zchsnsb8-8等。尽管铅基合金的性能没有锡基合金好，但是有许多客户仍然选择使用，因为它使用起来比较经济，其常用的牌号有zchpbsb16-16-2、zchpbsb1-16-1等。

　　巴氏合金的主要合金成分是锡、铅、锑、铜。锑、铜，用以提高合金强度和硬度。巴氏合金的组织特点是，在软相基体上均匀分布着硬相质点，软相基体使合金具有非常好的嵌藏性、顺应性和抗咬合性，并在磨合后，软基体内凹，硬质点外凸，使滑动面之间形成微小间隙，成为贮油空间和润滑油通道，利于减摩;上凸的硬质点起支承作用，有利于承载。

　　巴氏合金除制造滑动轴承外，因其质地软、强度低，常将其丝或粉喷涂在钢等基体上制成轴瓦使用。巴氏合金分锡基（见锡合金）和铅基合金两种。后者含锑10%～20%，锡5 %～15%，为防止成分偏析和细化晶粒，还常加入少量的砷。铅基合金的强度和硬度比锡基合金低，耐蚀性也差。

　　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.
