粉末冶金制品(硬质合金、过滤器除外)表面粗糙度评定方法分析

DISCUSSION ON METHODS FOR EVALUATING SURFACE ROUGHNESS OF P/M PRODUCTS (EXCLUDING CEMENTED CARBIDE AND FILTER)

表面粗糙度是反映粉末冶金制品(硬质合金、过滤器除外)质量的重要指标之一。现有的国标GB1031-83不适合粉末冶金制品表面粗糙度的评定。本文介绍了使用斧刃形触针测头定量评定粉末冶金制品表面粗糙度的方法。

Surface roughness is an important index showing the quality of P/M products(excluding cemented carbide and filter). The present paper gives a special description about how to guantitatively evaluate surface roughness of P/M products with testing head of axe edge form.
