本研究采用高速火焰喷涂(HVOF)沉积技术,将碳化钒(VC)和铜镍铬(CuNiCr)复合涂层应用于SS316不锈钢上,以解决不锈钢在海洋环境中的腐蚀问题。在室温环境下,在3.5%氯化钠溶液中进行电化学腐蚀,通过扫描电子显微镜(SEM)和能量色散光谱(EDS)对有涂层和未覆涂层样品的表面形貌进行检测。结果表明,涂层内由铜(Cu)、镍(Ni)和铬(Cr)组成的金属间黏合剂在氯化钠介质的影响下发生变质,从而导致出现衬底间的局部点蚀现象。有趣的是,在涂层配方中加入碳化钒(VC)显著地增强了表面的耐腐蚀性能,从而阻止了密闭腐蚀凹坑的出现。在不同类的涂层中,加入VC的效果最好,最小的腐蚀速率为72.38×10^(-3)mm/a,相比之下,SS316基底的腐蚀速率最快。

Among many factors known to alter the outcomes of T cell receptor(TCR)-induced proximal signaling,the role of human germline variants in dictating the individuality of the anti-tumor CD8 T cell response has remained challenging to ***,we describe a convenient strategy for molecular and functional characterization of phosphotyrosine-altering non-synonymous single nucleotide variations(pTyr-SNVs)that directly impact TCR-induced proximal phosphotyrosine motif-based signaling *** devise an experimental co-cultivation set-up comprising a C57BL/6 mouse-derived metastatic melanoma cell line engineered to constitutively present ovalbumin(OVA)antigens and retrovirally engineered syngeneic major histocompatibility complex(MHC)Class I restricted OVA TCR-transgenic CD8 T cells(OT-I).Using the synthetic version of pTyr-SNV rs1178800678-G/T-encoding integrin alpha 4(ITGA4)p.S1027I variant as a prototype,we show that under identical TCR stimulation conditions,genetically determined membrane-proximal immunoreceptor tyrosin activation motif(ITAM)results in increased tyrosine phosphorylation of 70 kDa zeta-chain-associated protein(ZAP70)and the levels of cytotoxic effector molecule granzyme B(GZMB),which in turn result in enhanced cytotoxic activity against metastatic melanoma cell *** strategy paves the way for rapid molecular and functional characterization of anti-tumor immune response-linked germline pTyr-SNVs so as to improve our understanding of the genetic basis of individual-to-individual differences in anti-tumor CD8 T cell response.
