摘要
本文将 Talysurf 6型表面形貌测量系统应用于金属断口的几何量测量中.在该系统上采用针描法测量金属断口表面,得到代表断口表面轮廓的模拟信号,应用计算机,计算断口表面的高度参数.根据体视学原理。对大量数据进行处理,获得金属断口的真实表面积.这种方法比定量金相法中估计 K 值求真实表面积的方法更为科学、合理.因此,针描法可以做为断口定量分析的一种有效方法.
The surface texture measuring system,Talysurf 6,which is used to measure the sur- face quality of a work piece,is applied in quantitative analysis of metal fracture.Metal fracture surface is measured by a stylus of Talysurf 6 to obtain the modeling signal of surface profile.With a computer the height parameters can be made out directly.Moreo- ver,according to stereology principle,the data can be processed and the true area of frac- ture surface can be obtained.It is more scientific and satisfactory than the method of quantitative metallography by which a K Value is estimated.Therefore,the stylus method can be also taken for an effective quantitative analysis method of fracture surface.
