Abstract

<p>Metal spray is beginning to come into use as a means of extending the life of steel bridges by preventing corrosion. A combined cycle test parameterizing the type of spray metal, scratch depth, surface preparation grade and the spray method was carried out to evaluate the effect of scratch caused during construction, the effect of the coating methods of the sprayed metal surface and the effect of spray methods. The test showed that the spray method, scratch depth and coating method affect durability, that coating on the spray metal surface can have adverse effects on durability and that even simple touch-up coating can be highly effective as a repair method.</p>
