Densiform process gives PM parts high fatigue strength.(PROCESS TECHNOLOGY)
Advanced Materials & Processes, August, 2006
Densiform is a powder metallurgy (PM) process that provides a full-density layer on critical surfaces up to 1 mm deep into the part, and an overall component density above 92% theoretical, reports Plansee Mitsubishi Global Sinter Group, Detroit, Mich. Complete elimination of surface porosity is said to enable performance similar to that of wrought steel in contact fatigue and rolling fatigue properties In the Densiform process, a sintered preform is produced by bonding the powder, compacting the preform, and final sintering.
