Vapor phase codeposition of Cr and Si on Nb-base in situ composites by pack cementation process

引用

Progress in Natural Science:Materials International 2013年第2期23卷 198-204页

作者： Bifei yuan yang Li Min Qiao Chungen Zhou School of Materials Science and Engineering Beijing University of Aeronautics and Astronautics

In order to identify suitable halide activators and pack compositions for codepositing Cr and Si to form diffusion coatings on Nb-base in situ composites by the pack cementation process, thermochemical calculation was taken to analyze the vapor pressure of halide species generated at high temperatures. Nh4Cl, NaF and CrCl3·6h2O were selected as the halide salts. The results of thermochemical calculations suggested that the pack powder mixtures, which contained Cr, Si, halide salts and Al2O3, may be activated by Nh4Cl and NaF. According to the thermochemical calculations, the pack powder mixture of 12Cr-6Si-5Nh4Cl-77Al2O3 (wt%) activated by Nh4Cl was formulated and coating deposition experiments were carried out at 1200 and 1300℃. With adequate control of pack compositions and deposition conditions, it was found that codeposition of Cr and Si could indeed be achieved at these temperatures. The coating has a three-layer structure, of which was mainly composed of Cr2(Nb,X) (X represents Ti and hf elements), Nb5Si3 and (Nb,Cr)3Si. Then the kinetics of coating growth process affected by temperature was studied. The experimental results of the oxidation showed that the coating can efficiently prevent substrate from oxidizing.

Expression of the inactive ZmMEK1 induces salicylic acid accumulation and salicylic acid-dependent leaf senescence

Journal of Integrative Plant Biology 2016年第8期58卷 724-736页

作者： yuan Li Ying Chang Chongchong Zhao hailian yang Dongtao Ren State Key Laboratory of Plant Physiology and Biochemistry College of Biological Sciences China Agricultural University

Leaf senescence is the final leaf developmental process that is regulated by both intracellular factors and environmental conditions. The mitogen-activated protein kinase（MAPK） signaling cascades have been shown to play important roles in regulating leaf senescence; however, the component（s） downstream of the MAPK cascades in regulating leaf senescence are not fully understood. here we showed that the transcriptions of Zm MEK1, Zm SIMK1, and Zm MPK3 were induced during dark-induced maize leaf ***, in-gel kinase analysis revealed the 42 k Da MAPK was activated. Zm MEK1 interacted with Zm SIMK1 in yeast and maize mesophyll protoplasts and Zm SIMK1 was activated by Zm MEK1 in vitro. Expression of a dominant negative mutant of Zm MEK1 in Arabidopsis transgenic plants induced salicylic acid（SA） accumulation and SA-dependent leaf *** MEK1 interacted with Arabidopsis MPK4 in yeast and high-Im pact activated MPK4 in vitro. SA treatment accelerated darkinduced maize leaf senescence. Moreover, blockage of MAPK signaling increased endogenous SA accumulation in maize leaves. These findings suggest that Zm MEK1-Zm SIMK1 cascade and its modulating SA levels play important roles in regulating leaf senescence.
