Abstract
The possibility of activated sintering by combined use of two activating additions is studied by experiment and demonstrated. The combined effect of two types of additives is studied: additives participating catalytically during gas phase generation, i.e., a carbon donor (Na2CO3 or BaCO3), and micro-additions of surface-active element (B). It is established that both combined additives (Na2CO3 + B or BaCO3 + B) accelerate PM alloy Fe–5%Si–1%C sintering considerably. The effect of combined additives is stronger than the effect of the additive components.
