Modeling of Fracture Toughness of Electroless Nickel (EN) Coatings K. Zangeneh1,F.Ashrafizadeh3,S.M. Monir-vaghefi3 (1.Department Of Engineering, Islamic Azad University-Saveh Branch, Saveh 39187...:In the present reserch, a model has been proposed for estimate fracture toughness of Nickel-phosphorus (EN)layers. For this purpose, high phosphorus (9%) EN coatings with thicknesses of 6, 12, 24, 36......
(MAB) and nickel-aluminum bronze (NAB) alloys have high mechanical properties and erosion-corrosion resistance to seawater [1,2]. These alloys are often used in marine industries. Although MAB and NAB... the nickel-aluminum bronze underlay deposit (Fig. 4(e)). The SEM images of welds are shown in Fig. 5. The high cooling rate and low alloying content of weld A produced the martensitic β phase......
