铁谱技术是20世纪70年代发明的一种新的机械磨损测试方法。它能从油样中将微粒分离出来，并按照微粒的大小排列在基片上，既能读出大小微粒的相对浓度，也能对微粒的物理性能作出进一步分析
Ferrography is a new method of measuring mechanical wear invented in 1970s. It can separate the particles from the oil sample and arrange them on the substrate according to the size of the particles. It can not only read the relative concentration of the particles, but also make further analysis of the physical properties of the particles.
油样铁谱分析能提供磨损残渣的数量、粒度、形态和成分四种参数，通过研究即可掌握有关的磨损情况。铁谱分析技术所使用的分析仪有铁谱分析仪和直读式铁谱仪等。
Ferrographic analysis of oil samples can provide four parameters of the amount, size, morphology and composition of wear residue, and the wear situation can be grasped through research. The analyzer used in ferrography analysis technology includes ferrography analyzer and direct reading ferrography analyzer.
