摘要

利用图像分析软件对粉末冶金工艺烧结合金在流化床渗碳过程中的孔隙率进行了研究，并与传统的孔隙率测量方法进行了比较。孔隙率是材料中空隙率的量度。总孔隙率的定义是孔隙空间的体积与材料的总体积之比，以百分比表示。数字图像和计算机软件的发展为粉末冶金材料孔隙率的测定提供了一种新的、合适的方法。

Determination of Porosity in Fluidized-Bed Carburized P/M Compacts Using an Image Software Analysis

The aim of this research was to study the porosity in carburizing in fluidized-bed on sintered alloys produced by powder metallurgy route using an image analysis software and to compare the obtained results with the conventional method for porosity measurements. Porosity is a measure of the void fraction in a material. The total porosity is defined by the ratio of the volume of void space to the total bulk volume of the material, expressed as a percentage. Development of digital images and computer software lead to a new and suitable method to determine the porosity of powder metallurgy materials.
