金属材料和合金的许多性质,例如强度,硬度等机械性能以及物理的化学的性质与金属的导电率有相应的关系,通过导电率的测定可以知道金属杂质含量合金成份、热处理状态等。用涡流法测量导电率有着方便,灵敏,无损等优点,因此应用日趋普遍,如波音公司,道格拉斯公司以及在MIL标准中都作了明确的规定,近几年来有些兄弟厂因接受国外订货也开始应用起来。 Many properties of metal materials and alloys, such as mechanical properties such as strength and hardness, as well as physical and chemical properties, have a corresponding relationship with the conductivity of the metal, and the content of the metal impurities and the heat treatment state can be known by measuring the electrical conductivity. Eddy current measurement of conductivity with a convenient, sensitive, non-destructive, etc., so the increasingly popular applications, such as Boeing, Douglas and MIL standards have made clear that in recent years some brothers plant to accept foreign orders also started Apply it.
