Powder Metallurgy Additive-Fe₃P
Promote sintering, accelerate the sintering process
FeP18 can be used in the manufacture of requirements for high hardness, high strength, good plasticity, good toughness, late plastic is not brittle fracture and airtight performance of good powder metallurgy products. Such as valve ducts, automotive ABS brake induction gear ring.
Promote sintering, accelerate the sintering process, and form eutectic reactions when Fe and FeP are sintered.
Fe-Fe3P-L(P), the liquid phase of P with the liquid phase in the gross under the action of suction brought around the iron particles, and soon diffused into the r-Fe, after cooling and melted in the α-Fe(P), so that the product is strengthened.
Activation sintering plays the role of solid solution strengthening, increasing the surface tension of the pores, so that the pores were a spherical state, play a role in filling closed pores, improve the density of products, improve product strength while improving product plasticity and toughness, can improve product airtightness performance.
The soft magnetic material can improve the product resistance, reduce the eddy current effect, and produce heat generation.
Fe-P iron-based products, in the P content of 0.45%,sintering strength can reach,300N/mm2 δ=3-5% ak=40J,δb=400N/mm2 ak=20-40J in the Fe-P-C system.
