Glacier金属公司,早在70年代中期就注意到传统轴承,主要是铅基镀层开始出现问题。最近几年从冶炼工艺入手,改进了现有材料的冶金工艺,同时开发出新的轴承材料。将镀层的含锡量重量比增加到(14～18)％,材料由铜基合金发展为铝基合金。这种材料不需要表面镀层,却能使轴承寿命达到20000～40000h,这与以前的材料只能工作5000h相比是很大的飞跃。 Glacier公司目前生产的中速柴油机轴承材料包括AS15和AS104。AS15是一种含锡20％的网状铝锡合金轴承材料,通过滚压结合到钢背上。这种轴承装在烧重油的柴油机上运行4400h后,状况良 Glacier Metals, as early as the mid-1970s noticed the traditional bearings, mainly lead-based coating began to have problems. In recent years, starting with the smelting process, the metallurgy of existing materials has been improved and new bearing materials have been developed. The coating containing tin weight ratio increased to (14 ~ 18)%, the material developed from copper-based alloys to aluminum-based alloys. This material does not require surface coating, but can make the bearing life of 20000 ~ 40000h, which is only 5000h compared to the previous material is a big leap forward. The medium-speed diesel bearing materials currently being produced by Glacier include the AS15 and AS104. The AS15 is a 20% tin mesh aluminum-tin alloy bearing material that is rolled onto the steel back. This bearing installed in the heavy oil burning diesel engine running 4400h, in good condition
