| Abstract: | Using Mo,Nb and Si elemental powders as raw materials,refractory metal silicide alloys(Mo1-xNbx)5Si3(x=0,0.2,0.4) were designed and fabricated by hot-pressing sintering technology.Both the corrosion behavior of(Mo1-xNbx)5Si3 intermetallic alloys in 1 mol/L HCl solusion and the effect of Nb content in alloys on the structure and corrosion resistance of the alloys were investigated by polarization curve and immersion corrosion.The results show that the grain size decreases,relative density and organization un... |
