| Abstract:In order to improve the surface wear resistance of cast iron cylinder head, research was carried out on the optimization of cladding material system, the influence of tempering temperature on the hardness of cladding layer, the optimization of cladding processing parameters and the control technology of cracks and blowholes. Finally, the cladding layer which meets with the technical requirements was obtained. It lays a technical foundation for the further application of surface cladding additive technology to the surface of wear-resistant cast iron parts. |
| Key words: surface cladding additive technology wear-resistant cast iron part |
