Ferro Silicon Zirconium For Wear-resistant Parts
Ferrosilicone-zirconium alloy is a special metal material composed of iron, silicon and zirconium. This alloy has excellent wear resistance and is widely used in the manufacture of wear-resistant parts, such as bearings, gears, guides and so on. The following will explain the various aspects of why iron silicon zirconium alloy is suitable for making wear resistant parts.
Description
Description
Ferrosilicone-zirconium alloy is composed of iron, silicon and zirconium, of which iron is the main element, accounting for the majority of the alloy. Silicon and zirconium are alloying elements in the alloy. Their addition can improve the hardness and wear resistance of the alloy.
The addition of silicon can form Fe3Si phase and FeSi2 phase in the alloy, which can improve the hardness and strength of the alloy. The addition of zirconium can form compounds such as ZrC, which have high hardness and wear resistance and can effectively improve the wear resistance of the alloy.
The microstructure of Fe-Si-Zr alloy is mainly composed of iron matrix, silicide and carbide. The iron matrix is the most important component in the alloy and has good toughness and strength. Silicide and carbide are distributed in iron matrix, which have high hardness and wear resistance, and are the main source of wear resistance in the alloy.
The silicification mainly consists of two phases, Fe3Si and FeSi2, whose hardness is 2000-2200HV and 1200-1500HV respectively. The carbides are mainly ZrC and Fe3C phases with hardness of 2200-2600HV and 1800-2000HV respectively. These phases with high hardness distribute uniformly in the alloy, which can effectively improve the wear resistance of the alloy.

Ferrosilicon zirconium alloy has excellent mechanical properties, with high hardness, strength and toughness. Alloy hardness is high because of the addition of silicide and carbide, these phases are very hard.
The high strength of the alloy is due to the good strength of the iron matrix, and the silicide and carbide can also increase the strength of the alloy.
The good toughness of the alloy is because the iron matrix can absorb and disperse the stress, so as to avoid the fracture of the alloy. These excellent mechanical properties make ferrosilicon zirconium alloy very suitable for the manufacture of wear-resistant parts.
