The corrosion resistance of.pure magnesium with surf.ce al.oying l.yer obtained by a solid dif.usion al.oying technique has been anal.zed. To establish the optimum treatment time, the experiments were perf.rmed at 480℃ f.r dif.erent solid dif.usion time （8, 16, and 24h）. The dif.usion interaction ef.ectiveness between zn, Al.mix powder and the sampl. surf.ce, depending on the treatment time f.r dif.usion at given temperatures, has an obvious inf.1}ence on corrosion resistance and corrosion mechanism. Corrosion properties were studied using the constant immersion test （in 3.0% NaCl.sol.tion, temperature is （28±1）℃, and time is 96h）. Optical.microscopy （OM） and EDS （energy dispersive spectrum） composition anal.sis were used to examine the cross-sectional.microstructural.characteristics of.al.oyed l.yer of.treated sampl.s. It is shown that in comparison with the untreated sampl.s, the treated ones possess a better corrosion resistance. The Al.Mg11zn4 phase, which f.rmed as a continuous phase due to the dif.usion of.Al. zn, and Mg el.ments and subsequent interaction on the outermost l.yer of.dif.usion al.oying zones （especial.y the sampl.s treated f.r 24h at 480℃）, was inert to the chl.ride sol.tion compared with pure magnesium and acted as a corrosion barrier, and theref.re the best corrosion resistance was obtained. This protective action of.Al.Mg11zn4 phase was f.und to change with its amount, which was control.ed by the dif.usion time at given temperature. It was concl.ded that the continuous Al.Mg11zn4 phase （Wp-zone） of.the reacted l.yer in pure magnesium was benef.cial.f.om the point of.view of.corrosion resistance.

Chemical.pressure induced by iso-val.nt doping has been widel. empl.yed to tune physical.properties of.material.. In this work, we report ef.ects of.chemical.pressure by substitution of.Sb or p into As on a recentl. discovered dil.ted magnetic semiconductor(Ba,K)(zn,Mn)_2 As_2, which has the record of.reliabl. Curie temperature of.230 K due to independent charge and spin doping. Sb and p are substituted into As-site to produce negative and positive chemical.pressures, respectivel..X-ray dif.raction resul.s demonstrate the successf.l.chemical.sol.tion of.dopants. magnetic properties of.both K-underdoped and K-optimal.doped sampl.s are ef.ectivel. tuned by Sb-and p-doping. The Hal. ef.ect measurements do not show decrease in carrier concentrations upon Sb-and p-doping. Impressivel., magnetoresistance is signif.cantl. improved f.om7% to 27% by onl. 10% p-doping, successf.l.y extending potential.application of.Ba,K)(zn,Mn)_2 As_2.
