Effect of Different Plasticizers on Technological Properties of a Powder Mixture of SP60KhN4D2M Steel

The effect of different plasticizers (zinc stearate, iron stearate, nickel stearate, dextrin, urea, dry paraffin, atomized bronze powder mixed with ethanol, etc.) on technological properties of powder mixtures is studied. It is established that powder mixtures compacted under a pressure of 700 MPa possess the best co-mpactibility. The following powder mixtures have the best technological properties: PL-N4D2M-RV (P-L‑8) + 0.6% C + 1.5% FKhS15 + 0.1% nickel stearate; PL-N4D2M-RV (PL-8) + 0.6% C + 1.5% FKhS15 + 0.5% bronze.
