Experimental Study And Results Analyzing Of Al/Municipal Solid Waste Ash Composites Materials

Chemical compatibility between matrix and reinforced phases of composites especially in liquid state processing plays a key role to determine the properties of end composite products. From the view points of lowering the preparation cost of composites and reusing resources, my experiments using grain of municipal solid waste ash (MSW) to reinforce aluminum matrix were carried out. The complex reaction equilibrium involved in the process have been approached theoretically together with different analyzing and examining measurements of XRD , SEM microstructures and properties , etc.The paper reviews different composite preparation techniques of chemical reaction. On the base of low-cost preparation matrix composites, the cost-effective processes using MSW as grain reinforced phases as raw materials as well as present chemical compatibility approaches are introduced in the paper. The analysis principles on the multi-component and multi-phase complicated systems are outlined using HSC Chemistry 5.11 thermo-chemistry databank.The Al-MSW ash composites were fabricated with P/M liquid sintering process to overcome the drawbacks of intensive reaction between metal and reinforced phases in casting routes. The raw materials of MSW ash, adopted from hangover of setting on fire of municipal life garbage. The technical parameters such as temperatures, atmosphere and reinforced phase contents are experimentally examined in the paper.As for the reactivity approach, the available database HSC Chemistry 5.11 thermo-chemistry databank is applied to detail the complex equilibrium in multi-component and multi-phase systems. With XRD and SEM characterization, the phases and morphology formed in the sintering processes are examined. As a result of Al-MSW ash composites, the optimized process control to realize the better phase and microstructure is presented.From the experimental results, the following conclusions were obtained:(1) The temperatures of sintering and the mate between Al/MSW effect on the quality of composites.(2) With the increasing of the municipal waste solid ash contents, debasing the density of aluminum matrix composites, and advancing the wear resistance and elasticity.(3) The performances of composites were stable, and composites can be used in different industries.Some capabilities of prepared Al-MSW ash composite samples are measured under the optimized process conditions. Coupled with the reported experimental results, the properties and potential applications of Al-MSW ash composite are discussed. Under the optimized process conditions, the Al-MSW ash composites can be generally used in civil industries such as automobile, parts and electric motors, etc.
