46—000 渗透探伤装置和其他46—100 基本概念46—101 渗透探伤法Penetrant testing method又称液体渗透探伤法。借助于显示剂的作用,观察从材料或零部件表面缺陷中吸出的渗透液显示缺陷的探伤方法。使渗透液渗入被检试件表面开口的缺陷中,去掉表面过剩的渗透液,再施加显示剂,由于毛细作用,则缺陷中的渗透液就会被显示剂吸出,从而显示出缺陷的迹痕,常用于检查非铁磁性材料表面缺陷。包括着色渗透探伤法和荧光渗透探伤法。
46-000 penetrant inspection equipment and other 46-100 Basic Concepts 46-101 Penetrant testing method Penetrant testing method, also known as liquid penetrant testing. By means of the function of the display agent, the flaw detection method of the permeate liquid aspirated from the surface defects of the material or part is observed. The permeate penetrates into the defect of the surface opening of the test object, the excess permeate on the surface is removed, and then the display agent is applied. Due to the capillarity, the permeate in the defect is aspirated by the display agent to show the defects , Commonly used to check the surface defects of non-ferromagnetic materials. Including coloring penetrating flaw detection and fluorescent penetrating flaw detection method.
