Electric arc spraying with dual wires is an economical coating process. The electrode fluctuation of titanium and aluminum wires was investigated to prepare intermetallic compound coatings. The combination of Ti-cathode and Al-anode leads to arc instability owing to unbalanced melting rates at electrode tips. Therefore, higher m.p. material can be used as the anode, while lower m.p. material can be used as the cathode for obtaining of better droplet dispersion from the corresponding wires, resulting in better preparation of compound coatings. Wire arc spraying provides a new attractive process for preparation of intermetallic compounds or alloys. The compounds are mainly prepared during the droplet deformation process on the substrate.
