Wire based on zinc and aluminum and its use in thermal spraying for corrosion protection

Abstract

The wire based on zinc and aluminum contains from 8 to 33% by weight of aluminum and up to 500 ppm of indium, in addition to zinc and the usual impurities. This wire is suitable for thermal spraying for corrosion protection, especially corrosion protection against high atmospheric humidity and high chloride ion concentrations according to DIN 50021-ss.
