Study on Corrosion Resistance of Zinc or Aluminium Electric Arc-Sprayed Coatings

The corrosion resistance performance of zinc or aluminium sprayed coatings, especially that of electric arc-sprayed ones, is studied. It is verified that. The adhesive strength of Al arc-sprayed coating is better than that of flame-sprayed one, and the arc-spiayed coating after the porosity-sealed treatment has much better corrosion resistance than the flame-sprayed one.
