| Abstract: |
| Three types coating that had fine cavitaion erosion resistance,derived from NiCr feedstock,were fabricated on abnormity bent surface of aluminum alloy workpieces using air plasma spraying(APS)with and without cooling by gasified CO2and high velocity oxy-fuel(HVOF). The combination between coatings and substrate, and the composition, microharness and porosity of the coatings were reviewed. The obtained results shows that HVOF sprayed coating has bad combination with substrate where the flame can't vertically sprayed on; APS sprayed coating without cooling by gasified CO2curls and has distinct crack; APS sprayed coating cooled by gasified CO2has good combination with substrate in anyplace and has not crack. It can be concluded that APS is an effective method to produce functional coatings on aluminum abnormal bent surface at present. |
