Repairing cracked aluminum plates by aluminum patch using diffusion method

摘要: The aim of this work is to scrutinize the importance diffusion bonding temperature, pressure and time on repair a cracked aluminum plate while maximum tensile strength under quasi-static loading has been investigated. method was used connect patches central mode I cracks in thin plates. Here, process repairing pieces made or alloys involved chemical mechanical step remove oxide press patch piece temperature difference at certain time. repaired underwent tolerable amount force obtained different situations. Having assigned five temperatures, 300, 400, 500, 550 600 C, as well four test times 30, 60, 120 180 min pressures 10, 20, 50, 80 110 bar, we utilized fractional factorial design approach perform 40 tests there seen 10 mm initial crack samples. Experimental results showed that optimum connection resulted °C bars within where tolerated by vs. unrepaired increased 92 %. Therefore, having weighed using bonding, suggest type can be proper cheap alternative composite adhesive patches.
