Penetrant (ndt testing)
染料渗透检测 (DPI)，也称为液体渗透检验 (LPI) 或渗透检测 (PT)，是一种应用于检测所有非多孔材料（金属、塑料和陶瓷）表面断裂缺陷的方法，该方法应用广泛、成本低廉。渗透剂适用于所有的金属材料和有色金属材料。不过对铁磁性元件，通常采用磁粉检测进行次表面探测。
A penetrant is a coating that penetrates microscopic cracks on a part for subsequent inspection.
This method is followed by an emulsion spraying cleaning process and than a developer powder process.
It is mainly used on aerospace industry to control structural part of an aircraft.
