做淬透性试验,如何在试样上按标准要求的距离打出准确的硬度值,这一问题一直困绕着每一个试验工作者.经过实践,本人总结出一种简单、实用的划线法.现介绍给广大力学同仁.首先取一张纸,按标准要求的距离即1.5mm,3mm和5mm等在纸上画出,随后拿一张复写纸,放到需要打硬度的平面上,用圆珠笔或划针,按规定的距离复印到试样上即可.而后按规定的复印点进行试验.效果很好.

To do the hardenability test, how to make accurate hardness value according to the required standard distance, this problem has been trapped around every experimenter.After practice, I concluded a simple and practical method of marking Now introduced to the majority of my colleagues in mechanics.First take a piece of paper, according to the standard requirements of the distance that is 1.5mm, 3mm and 5mm drawn on the paper, then take a carbon paper, put the need to fight the hardness of the plane with a ballpoint pen Or stitches, according to the provisions of the distance to the sample can be copied. And then according to the provisions of the copy point test. Good effect.
