Metallic-Ceramic Combination of HVOF Deposited Layers for Corrosion Protection Applications

Abstract:

Article Preview

The paper presents some preliminary results regarding the combining of metallic, Cr3C2-20(Ni 20Cr) and ceramic (TiO2) HVOF deposition of layers for corrosion protection applications. The deposited layers morphology was investigated by SEM and optical microscopy. The corrosion protection efficiency of the deposited layers was evaluated in 0.3M NaCl solution. The maximum corrosion protection efficiency was determined for the combination of layers using the carbide as the first layer although the inverse deposition order showed a small decrease. Depending on the main application (corrosion versus wear) one or the other are recommended.
