The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下,3Cr13基体合金的磨损机理为显微切削和变形磨损;低体积分数的复合材料磨损机制以变形磨损为主,兼有少量的切削磨损机制;高体积分数的复合材料磨损机制以变形磨损为主,兼有应力疲劳磨损和脆性相剥落磨损;在油润滑摩擦条件下,3Cr13基体合金的磨损以磨粒磨损为主;低体积分数的复合材料磨损为磨粒磨损和疲劳磨损;高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。

When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.

结果表明:通过控制制备条件可获得具有纳米结构的钛阳极涂层;当Sn的摩尔分数为83%时,涂层主要为金红石相的O2固溶体;当Sn的摩尔分数为44%时,涂层中金红石相O2固溶体和萤石结构的O2固溶体共存;当Sn的摩尔分数为17%时,涂层由萤石结构的O2固溶体组成;高于450 ℃退火时,含83%Sn的涂层中出现CeO2相,而在含83%Ce的涂层中没有出现SnO2相,表明在相同的溶质浓度下,萤石结构的O2固溶体比锡基金红石相O2固溶体具有更好的热稳定性;而涂层中的SnO2具有明显改善涂层分散性的作用。

To ensure an optimal separation, three fractions should be collected: the limonene fraction, an intermediate fraction that forms during the rapid increase in temperature after collection of the limonene fraction, and the carvone fraction.

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明,渗滤液中Cu大部分为腐殖质络合态,并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变;Zn则主要表现为与S~(2-)的络合,其络合程度随模拟填埋场内还原性环境形成而加剧,生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。
