鐵基合金粉是Fe.Cr.Ni為主要元素的合金粉。該合金粉韌性、塑性良好，耐腐蝕性好，在多種腐蝕性較強的介質中化學性能穩(wěn)定，突出抗裂性好。在合金中加入Mo，使涂層具有較好的耐硫酸、鹽酸和磷酸腐蝕性。可用于耐腐蝕、高強度、高耐磨性要求的軸類、閥類、輥類的修復和保護。如燃氣渦輪噴氣發(fā)動機的壓氣葉片，礦山耐磨板、帶等。

為了提高涂層的硬度和耐磨性，可加入適量的B和Si。

Main elements in iron base alloy powder. For iron, Chromium, nickel, the alloy ductile, plasticity is good, good patience corrosion. In a variety of highly corrosive medium chemical performance is stable, highlight the crack resistance is good resistance to sulfuric acid, hydrochloric acid and phosphoric acid corrosion. Can be used for corrosion resistance, high wear resistance requirements of axial, valve type, roller of repair and protection. Such as gas turbine jet enging air blade, Mining wear, resisting plate, belt etc. ???

In order to improve the coating hardness and abrasion resistance can be added to fitness B and Si.
