DESIGN A TECHNICAL PROCESS OF THERMAL SPRAY APPLIED TO THE CRANKSHAFT REHABILITATION OF SHIP

Abstract

The metal spraying was discovered very early. The important uses of this method are the processing and restoration of damaged machinery-parts that are corrosion or incorrect. Material which only needs a small amount compared to the whole of new parts that must be reproduced, used in the restoration. In some cases, restoration of the machinery-parts will have quality and the long-life higher than the new parts. This report presents a study that is about the design of combust-spaying and the heat treatment process.
