一种基体表面的固体润滑复合涂层及其制备方法

, 2017
本发明提供一种基体表面的固体润滑复合涂层。该复合涂层是由硬质相纳米晶CrC与润滑相a-C组成，形成CrC-a-C复合涂层，不仅保持了CrC硬质涂层高硬度、低磨损的特点，同时具有a-C材料优异的自润滑特性。本发明采用多弧离子镀技术，以金属Cr为靶材，以高纯Ar为工作气体，C2H2为反应气体，在基体表面沉积该CrC-a-C复合涂层，能够通过控制Cr靶电流与反应气体C2H2流量而调控复合涂层中CrC相与a-C相的含量。该复合涂层的硬度高达31GPa，磨损率达10-16m3-N·m量级 ...

半湿润区长期施肥对土壤结构体分形特征的影响

, 2007
利用黄土高原南部半湿润地区长达25年田间肥料定位试验0—20 cm土层土样,研究了长期不同施肥模式与土壤结构体大小、结构体分形特征与土壤肥力的相互关系。结果表明,长期不同施肥模式下土垫旱耕人为土结构体分形特征存在一定差异:7种施肥处理土壤结构体分形维数分布在2.43882~.6363之间,其中以化肥+厩肥处理土壤结构体分形维数最大,不施肥土壤结构体分形维数最低,说明化肥与有机肥长期配施对土壤团聚体结构分布影响较大。相关分析发现,土壤结构体分形维数与52~mm团聚体间具有极显著的正相关关系(r=

生物炭对矿区不同压实度土壤水分入渗和蒸发的影响

Shuitu Baochi Xuebao
目的探究水稻秸秆生物炭对矿区压实土壤水分入渗和蒸发特征的影响，为秸秆废弃物的资源化利用和矿区土壤修复提供依据。方法在模拟1.2、1.3、1.4、1.5、1.6 g/cm3（T1.2~T1.6）压实处理下，设置4种生物炭施量（0、2%、4%、6%）进行室内土柱模拟试验。结果1）不同施用量生物炭均减缓不同压实土壤湿润锋向下运移速率，土壤水分累积入渗量随生物炭施用量的增加呈先增加后减少趋势。2%施量处理均增加不同压实处理的累积入渗量，其中T1.2、T1.3、T1.5和T1.6时 ...
