Magnetic Particle Testing
Magnetic particle testing is a non-destructive testing method for detection of imperfections on or just below the surface of ferrous metals.It is a quick and reliable technique for detection and location of eg.surface cracks.
A magnetic flux is send through the material.At the location of the imperfection a leakage field is formed.This attracts metal iron dust,which is sprayed onto the surface.The length of the imperfection can be determined very reliable.Magnetic particle testing does not indicate the depth of the imperfection.Acceptance criteria define whether or not the indication is non-acceptable (a defect) or not.
Magnetic particle testing can be used for all ferrous metals,such as carbon steel,low-alloy and cast iron.The main use of Magnetic particle testing is for welds and heat affected zones.It can be applied to relatively rough and dirty surfaces but flaw sensitivity is decreased for this.Fluorescent particles can be used when maximum sensitivity is required.

磁粉探伤
磁粉探伤是一个非或略低于黑色金属表面缺陷检测的无损检测方法.这是一个用于检测和定位,例如快速,可靠的技术.表面裂纹.
阿磁通量通过发送材料.在一漏磁场形成的不完善的位置.这吸引了金属铁尘,这是表面上喷涂.不完善的长度可以决定非常可靠.磁粉检测并不表明该缺陷的深度.验收标准界定是否标志是不接受（缺陷）或不.
磁粉检测可用于所有黑色金属,如碳钢,低合金钢,铸铁等.在磁粉检测的主要用途是用于焊缝和热影响区.它可应用于相对粗糙和肮脏的表面缺陷的敏感性,但这一下降.荧光微粒时可以使用的最高灵敏度是必需的.
不是很标准.
