镍铝合金丝是电弧喷涂最好的打底丝材 ,利用合金丝中镍、铝元素与氧发生放热反应 ,提高了飞行粒子的温度 ,从而达到较高的结合强度。电弧喷涂镍铝合金丝扩大了电弧喷涂的应用领域 ,在修复轴类、大面积构件的防护、零部件的修复与强化、装饰等方面起到关键的作用
Nickel-aluminum alloy wire is the best base material for arc spraying, which utilizes the exothermic reaction of nickel and aluminum elements with oxygen in the alloy wire to increase the temperature of the flying particles so as to achieve higher bonding strength. Arc-sprayed nickel-aluminum alloy wire expands the field of application of arc spraying and plays a key role in repairing shafts, protecting large-area components, repairing and reinforcing parts, and so on
