铁谱技术诞生于70年代初,首先被用于飞机发动机的健康诊断,到80年代初,已被用于民用工业。铁谱技术所用的仪器有分析式铁谱仪、铁谱显微镜和读数方便的直读式铁谱仪。分析式铁谱仪是利用高强度磁场,使带有磨屑的润滑油或液压油在沿倾斜放置的玻璃片上流过,由于该玻璃片置于磁场上方,在磁场力、重力、油内摩擦力的共同作用下,铁磁性磨屑有规律地在玻璃片上沉积,构成谱片。利用铁谱显微镜(或电子显微镜)可对谱片上的磨屑进行观察,根据它们的形状、大小可判断机器部件的磨损类型和磨损程度。同时,通过装置在显微镜上的光密度计对谱片上不同位置处的磨屑覆盖面积进行读数。根据分析式铁谱仪的磁场分布和铁磁性磨屑在磁场中被磁化的程度,大颗粒的磨屑首
Ferrography was born in the early 1970s and was first used for the health diagnosis of aircraft engines. By the early 1980s, ferrography was used in the civilian industry. Instruments used in ferrography are analytical spectrometers, ferrographs, and direct-reading spectrometers that are easy to read. Analytical iron spectrometer is the use of high-intensity magnetic field, so that with wear debris lubricating oil or hydraulic oil flow along the inclined glass sheet placed on the magnetic field above the magnetic field, gravity, oil friction The combined effect of force, ferromagnetic wear debris regularly deposited on the glass to form a spectrum. Ferrographs (or electron microscopy) can be used to observe debris on the wafers, and their shape and size determine the type of wear and tear on the machined parts. At the same time, the debris coverage area at different locations on the wafer was read by a microscope mounted densitometer. According to the analysis of the magnetic field distribution of iron spectrometer and ferromagnetic wear debris in the magnetic field is magnetized to the extent of large particles Debris
