今天,作为各种滑动部件使用的铸铁,有钒铸铁、铋铸铁、锑铸铁、镍铬耐磨铸铁、硼铸铁、铅铸铁、高磷铸铁和石墨生长铸铁等。但是,这些产品几乎都只是经机械加工后使用的。日本科学技术研究所对铸铁的特性加以剖析,研制成现在的所谓“石墨面金属”。石墨面金属,就是把铸铁机械加工后,用酸将滑 Today, cast iron used for various sliding parts includes vanadium cast iron, bismuth cast iron, antimony cast iron, nickel-chromium abrasion-resistant cast iron, boron cast iron, lead cast iron, high phosphorus cast iron and graphite cast iron. However, almost all of these products are used after machining. Japan Institute of Science and Technology analysis of the characteristics of cast iron, developed into the so-called “graphite surface metal.” Graphite surface metal, that is, cast iron machining, the acid will slip
