Fretting Damage

Electroless plating technology used to alleviate fretting damage of titanium alloy was studied, Ni-Tl-B coatings were prepared, process optimization was worked out by the orthogonal table, deposition rate and solution consumption per hour and the initial friction coefficient and the bearing cycles under a low friction coefficient were chose as the index to calculate the range according to the economical efficiency and the application of coating under the surface morphology analysis and the fretting friction coefficient test, optimum process was finally worked out. Surface morphology was analyzed by TM-1000 scanning electron microscope and the fretting friction coefficient was tested by the DELTALAB-NENE fretting wear tester. The results shows that the surface morphology of the Ni-Tl-B coating are all typical cell structure which will be slightly different when the process changes and the optimum Ni-Tl-B coating has outstanding fretting damage resistance.

Remediation Process

Abstract A full-cycle water remediation process has been developed by expanding the capacity of an existing water treatment technology that uses combined ozonation and ultrafiltration membrane processes. The developed water reclamation process treated the effluent of a full-scale wastewater treatment plant in Canada that uses biological treatment processes to treat municipal wastewater, and reduced the colour, turbidity, suspended solids, iron and pathogen content of the effluent. The removal of hardness from the wastewater effluent was accomplished by the precipitation process. The use of lime (0.2 g/L) in the presence of NaOH operating at pH 11 showed the best results, reducing the water hardness by 89.1%. The advanced treatment capability of ozonation (8–10% w/w) and polyvinylidene fluoride (PVDF) hollow fiber ultrafiltration (UF) membrane produced a reliable source of water for municipal, industrial and agricultural use. The developed process offers important environmental benefits by reducing the diversion of water from sensitive ecosystems, decreasing wastewater discharge and preventing pollution.

Soil And Water

In the last decades increased global environmental concerns to water and soils pollution. The main concerns are related to the contamination of the ecosystem, food security, and human health since many of the contaminants present in soil and water (residues of pesticides and antibiotics, genes of resistance to antibiotics, and heavy metals) are absorbed by plants and enter the food chain. Remediation of the contaminated water and soil to ensure sustainable water supply and food production is urgently needed. The use of biochar can have a positive effect on this remediation process. There are several studies that demonstrate the biochar’s ability to block/reduce the contaminating effect of pesticides, antibiotic residues, antibiotic resistance genes, and heavy metals. The objective of this chapter is to carry out a comprehensive review of the effect of using biochar on the availability/transmission of these contaminants to the soil and food supply chain.
