摘要
简要地介绍了单个颗粒间的附着力与粉体层抗拉强度之间的关系，对粉体附着力测试的原理、方法和几种常用的测试装置进行了分析比较，并通过实例说明了粉体拉伸试验装置的应用。
In this paper,the relation between adhesion of powder parical and tensile strength of powder layer are first introduced simply. The principle,method of test powder adhesion,and several commonly used test instruments are then compared and analysed. Finally,the applications of powder tensile test instruments are explained by some practical examples.
