摘要：

ISO Standard 23519:2010 defines the surface roughness of sintered metal parts: Rk and Rpk, and it intends to provide relevant surface roughness data regardless of porosity,- however the data reliability tends to be insufficient in practice. The following parameters might influence the surface roughness data in accordance with the standard such as; measuring probe, instruments, filters, and others. The effect of such parameters was investigated and compared with an optical method using white light interferometry. 3 different measuring instruments were used. The measured surfaces of specimens having density of 6.4, 6.8 and 7.2 are punch facing side. In this study, details of the results are presented. ©2025 Japan Society of Powder and Powder Metallurgy.
