Thi. work studi.d the effects of addi.g Zr and Mn i. amounts less than 1wt%on the mi.rostructure,mechani.al properti.s,casti.g properti.s,and corrosi.n resi.tance of Mg-Zn-Cu alloys contai.i.g 2.5wt%Cu and 2.5wt%-6.5wt%Zn.The hardness and electri.al conducti.i.y measurements were used to fi.d an opti.al heat treatment schedule wi.h the best mechani.al properti.s.i. has been establi.hed that Zr si.ni.i.antly i.creases the yi.ld strength of the alloys due to a strong grai. refi.ement effect.However,the presence of Mn and Zr has a detri.ental effect on alloy’s elongati.n at fracture.i. was shown that the preci.i.ati.n of the Mg_(2)Cu cathodi. phase i. the alloy structure negati.ely affects the corrosi.n behavi.r.Nevertheless,the addi.i.n of Mn decreases the corrosi.n rate of the i.vesti.ated alloys.The best combi.ati.n of the mechani.al,casti.g,and corrosi.n properti.s were achi.ved i. the alloys contai.i.g 2.5wt%Cu and 5wt%Zn.However,the Mn or Zr addi.i.n can i.prove the properti.s of the alloys;for example,the addi.i.n of Mn or Zr i.creases the flui.i.y of the alloys.

A novel combi.ed method for the formati.n of composi.e coati.gs on the Mg-Mn-Ce alloy i. developed.Cerami. li.e matri. was formed on the Mg alloy surface by the plasma electrolyti. oxi.ati.n.Then the samples were subsequently processed by di.-coati.g i. an alcohol suspensi.n of superdi.persed polytetrafluoroethylene and sprayi.g wi.h the tetrafluoroethylene telomers soluti.n.SEM,OSP,and SPM was used to study structure of formed surfaces.i. was establi.hed by measurements of CA and CAH,as well as surface free energy calculati.ns that formed coati.gs demonstrate superhydrophobi. properti.s due to the presence of an i.regular hi.rarchi.al surface structure and low surface free energy of fluoropolymers.The coati.g preserves i.s hydrophobi. properti.s after exposure to hi.h and low temperatures,for a long ti.e as well as bei.g i. corrosi.e envi.onments.EDS and XRD data analysi. confi.med the presence of organofluori.e compounds i. the composi.e layers,i.cludi.g i. the form of crystalli.e polytetrafluoroethylene.Usi.g potenti.dynami. polari.ati.n test and Ei.,i. was found that the resulti.g coati.gs si.ni.i.antly i.crease the corrosi.n resi.tance of Mg materi.l.These data are also confi.med by salt spray tests for 40 days.i.corporati.n of fluoropolymers addi.i.nally decrease coati.gs coeffi.i.nt of fri.ti.n.

为了开发新型铸造镁合金,研究含长周期堆垛相(LPSO)和W共晶相的Mg−Zn−Y−Zr合金。硬度和电导率测试结果表明,T6热处理的温度是合适的。与含W相的合金相比,含LPSO相合金的热裂敏感性更低,这与合金的凝固区间有关。然而,两者具有相同的流动性。在T6条件下,增加Y含量可以提高合金的屈服强度,但合金的其他拉伸性能基本相同。与含W相的合金相比,含LPSO相的合金具有更优的耐腐蚀性。含LPSO相的Mg−2.5Zn−3.7Y−0.3Zr(质量分数,%)合金具有良好的铸造性能和力学性能,其腐蚀速率为2 mm/year。
