10 PM-AG101P POWMET SILVER POWDER 925 FOR PLM, µm PARTICLE SIZE POWDER HANDLING Precious metal powders are sensitive to the uptake of humidity which may lead to powder particle agglomeration and subsequent degradation of powder flow. The powder is therefore packaged under dry protective gas in sealed cans. The cans should be opened and the powder should be processed only in rooms with humidity control. PLM PROCESS PARAMETERS Parameters will vary depending especially on laser melting equipment. Please follow the process parameters recommended by your equipment supplier for metals with high conductivity and high reflectivity. Specialists from Legor Group are available for consultancy on optimum support structures and process parameters depending on equipment as well as geometry (wall thickness) and design of the items. POST TREATMENT No particular stress-relief heat treatment is required before or after removing the parts from the PLM platform. However, a simple age-hardening treatment is recommended for strengthening the parts and for increasing the wear resistance and long term surface quality and luster of the finished parts. In fact a significant age-hardening effect to a final hardness of 140 HV can be obtained by means of a heattreatment at 300 C for 60 min in air. Different to age-hardening from a slowly cooled as-cast state, there is no need for a homogenization treatment preceding the age-hardening treatment: the age-hardening effect is simply obtained directly from the PLM state.
