感应熔敷WC/Ni基复合涂层的组织和性能

采用高频感应熔敷技术，以Ni60A自熔合金粉末、微纳米碳化钨粉末为原料，在16Mn钢表面制备出以微纳米WC颗粒为增强相的Ni基金属陶瓷涂层，并测试了涂层的显微硬度。利用磨擦磨损试验机，以45#钢为对磨偶件，评价了涂层的滑动干磨擦性能。实验结果表明：涂层的硬度为890～910,磨擦系数为0．3-0．4，耐磨性比16Mn钢提高4倍以上。     

Pilot Study on Nanofiltration Combined with Ozonation and GAC for Advanced Drinking Water Treatment

IntroductionThe conventional process for surface water treatment,which consists of flocculation, sedimentation and filtrationcurrently, had been applied inproducingdrinkingwater formany years. Although this process can remove turbidityand bacteria in surface water effectively, only about from20% to 30% of natural organic matter ( NOM) can beeliminated. When the purified water is disinfected bychlorination, these NOMs may react with chlorine. As aresult some dis…

Temperature effects on surface activity and application in oxidation of toluene derivatives of CTAB-SDS with KMnO4

The γ_cmc values of CTAB-SDS decrease from 63.67 mN/m at 10‡C to 36.38 mN/m at 90‡C, slightly lower than those of either CTAB or SDS. Correspondingly, the CMC of CTAB-SDS decreases almost by half. The increase of surface activity of CTAB-SDS can be attributed to the relatively weak electrostatic interaction at high temperature, which is supported by the increase of solubility of CTAB-SDS with rise in temperature. Catalytic effect on oxidation of toluene derivatives with potassium permanganate follows the order CTAB-SDS > SDS > CTAB. This is not caused by the dissociative effect of CTAB-SDS with low surface activity at low temperature, as seen from the fact that almost all oxidative products can be retrieved for different toluene derivatives and surfactants by mimicking the conditions of reaction. In the emulsifications of toluene derivatives at 90‡C, the time that turbid water layers of surfactant solutions take to become clear is the same as that of the catalytic effect on oxidation of toluene derivatives. Thus, it can be inferred that surfactants can improve the oxidation yields of toluene derivatives by increasing the contact between two reacting phases.     

An Efficient Selective Oxidation of Alcohols with Potassium Permanganate Adsorbed on Aluminum Silicate under Solvent-free Conditions and Shaking
