The Study of Electroless Ni-P Coating on Aluminum Tyre Mold

Abstract:

In order to improve the service life of the aluminum tyre mold, AC7A aluminum alloy was processed by electroless Ni-P plating under orthogonal experiment. The coating was characterized by Scanning Electron Microscopy (SEM) ,Energy Dispersive Spectrometer (EDS) and X-ray Diffractometer (XRD).The experimental results showed that the electroless Ni-P coating on aluminum alloy was amorphous structure, with high hardness and good corrosion resistance; the structure became crystal structure after heat treatment, and the hardness of the coating was improved, could catch HV828; the thickness of the coating was 28μm. The results showed that the hardness and thickness of the coating meet the requirement of the AC7A aluminum alloy tyre mold, and the service life of the aluminum tyre mold were improved.
