铁基合金粉是Fe.Cr.Ni为主要元素的合金粉。该合金粉韧性、塑性良好，耐腐蚀性好，在多种腐蚀性较强的介质中化学性能稳定，突出抗裂性好。在合金中加入Mo，使涂层具有较好的耐硫酸、盐酸和磷酸腐蚀性。可用于耐腐蚀、高强度、高耐磨性要求的轴类、阀类、辊类的修复和保护。如燃气涡轮喷气发动机的压气叶片，矿山耐磨板、带等。

为了提高涂层的硬度和耐磨性，可加入适量的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.
