Research on the Optimization of Process Parameters for ZL205A Additive Remanufacturing
In order to solve the problems of cumbersome,high cost,and long cycle repair process for damaged ZL205A aluminum alloy components in ships.The key process parameters for arc additive remanufacturing of ZL205A aluminum alloy were carried out.A comprehensive analysis was conducted on the effects of single-path and single-layer welds of aspect ratio and dilution rate,microhardness and its XRD patterns,frictional performance,electrochemical performance,interlayer cooling time of sigle-path and multi-layer welds,and overlap rate of single-layer and multiple-path welds.The optimal process parameters combination such as welding speed,wire feeding,dry elongation,interlayer waiting time,and overlap rate were obtained.And sample tests were conducted to verify the results.The research results can provide theoretical basis and technical guarantee for high-quality and rapid repair of marine equipment.
