英国最近采用了一种新的检查非磁性材料表面上裂痕的方法,这方法是利用一种带有萤光性墨水,它的效果比以前所用的“白粉吸附试验法”改进很多,实际上这个新方法就是从“白粉吸附试验法”的基础上发展出来的,不过它不用矿物油而用一种特殊的,里面曾加过一种含有萤光性颜料的液质介体,当我们用了吴 The United Kingdom has recently adopted a new method of inspecting cracks on the surface of non-magnetic materials. This method utilizes a fluorescent ink. Its effect is much better than the previously used “white powder adsorption test method”. The new method was developed based on the “Powder Adsorption Test Method,” but it uses a special kind of liquid mediator that contains fluorescent pigments instead of mineral oil when we used it. Wu
