Conventionally processed powder metallurgy materials often exhibit open microporosity at the surface. While it is a natural part of the process, this microporosity can affect the measurement of surface finishes. To cover this and other issues that arise from measuring the surface finish of powder metallurgy, ASTM International Committee B09 on Metal Powders and Metal Powder Products has developed…
