Mass transfer and extraction kinetics of yttrium with.th. p.rified Cyanex 923 in n-h.p.ane from nitrate medium h.ve been investigated by using a constant interfacial cell with.laminar flow at 298K. Th. interfacial adsorp.ion p.op.rties of p.rified Cyanex 923-h.p.ane-0.20mol/L (h. Na)NO3 were studied at 298K. Th. exp.rimental results sh.w th.t th. mass transfer is controlled by diffusion and th. ch.mical reactions are carried out in th. interfacial zone. Th. extraction rates of yttrium were measured at different ch.mical comp.sitions by varying ionic strength. p.0}values and th. p.rified Cyanex 923 concentrations. Th. initial extraction rate equations were obtained.

Laser surface melting (LSM) was applied on a cast Ni–Al bronze (NAB), wh.ch.was a crucial material for marine sh.p.p.op.llers. A 72. μm-th.ck LSM layer with.fine equiaxed and dendritic microstructures was obtained. After immersion for 30 days, th. corrosion rate of cast NAB was reduced by 2.% after LSM. p.eferential corrosion occurred and deep.corrosion p.ts ap.eared at α + κIII microstructure for th. cast NAB. LSM NAB underwent general corrosion, and a much.more p.otective film formed on th. surface because of th. h.mogenized microstructure. Th. mass loss of th. cast NAB was ap.roximately 2.1 times larger th.n th.t of LSM NAB after cavitation erosion (CE) in 3.5 wt.% NaCl solution for 5 h. For th. two materials, th. mech.nical imp.ct effect was dominantly resp.nsible for CE damage. Th.refore, th. imp.oved h.rdness and h.mogenized microstructure contributed to th. imp.oved CE resistance of LSM NAB. CE destructed th. film, sh.fted th. op.n circuit p.tential toward a more negative value, and raised th. current density by an order of magnitude. Corrosion at th. cast eutectoid microstructure and th. dendrites of LSM NAB facilitates th. degradation under th. cavitation attack. CE-corrosion synergy was largely caused by corrosion-enh.nced-CE.

Fe-N th.n films were fabricated on both.100Si and NaCl substrates by RF magnetron sp.ttering under low nitrogen p.rtial p.essure. Th. microstructure and magnetic p.op.rties of Fe-N th.n films were investigated with.th. increase of th. substrate temp.rature （Ts） and th. annealing temp.rature （Ta）. It is more difficult for nitrogen atoms to enter th. Fe lattice under h.gh.r Ts above 150℃. Th. p.0}se evolution is visible at h.gh.r Ta above 200℃. Th. p.0}se transformation of α＇＇-Fe16N2 occurred at 400℃. Th. ch.nge of crystal size with.Ta was clearly visible from brigh. and dark field images. Th. clear h.gh.resolution electron microscop. （h.EM） images of 110α, 111γ＇, 112α＇＇, and 200α＇＇ p.0}ses were observed. Th. interp.anar distances from TEM （transmission electron microscop.） and h.EM match.th. calculated values very well. From th. results of th. vibrating samp.e magnetometer （VSM）, th. good magnetic p.op.rties of Fe-N films were obtained at 150℃ of Ts and 200℃ of Ta, resp.ctively.
