Abstract
Remanufacturing technology has a wide range of applications in the repair of scrapped parts with a certain remaining service life. In this work, a scrapped crankshaft fabricated from nodular cast iron that had failed from working surface wear was remanufactured via a plasma cladding process. Taking into account the wear amount on the working surface and the characteristics of nodular cast iron, in this article, cladding layer parameters were designed and two types cladding powders, Fe-based and Ni-based, were prepared, respectively, to perform the cladding experiment. After examining different process parameters, relatively smooth cladding layers were obtained using four powders. The cladding experiment results showed that the powder No. 3 exhibited superior qualities when combined with proper processing parameters. When applying powder No. 3 to the main journal of crankshaft, a higher quality of cladding layer was achieved.
