An innovative study: Developing of a continuous coating method for steel sheets or plates
AbstractInnovation is the application of an idea, item or a new process to the real life for income. In coating sector, it is possible to talk about some new and innovative processes for different kind of parts, especially for small parts. However, the subject of coating for steel sheets or plates having large surfaces with Fe-based alloys, especially for resistance to wear, is still open for investigation. For coating of large steel surfaces, common method is welding using different kind of electrodes. However, coating with welding has some disadvantages such as; dependent on electrodes, low coating rate, high surface roughness and so on. However, in the continuous coating method that was invented under this study has more advantages. In the experimental study, st 37 steel plates having dimensions of 4 x 800 x 800 mm were coated using continuous coating method with three different kinds of Fe-based alloys, austenitic manganese steel, high chromiumhigh carbon alloy and nodular cast iron, with the thickness of 4 mm. After coating process, microstructural investigation was conducted using optical and scanning electron microscope (SEM) with EDS analysis and microhardness measurements were obtained from coating to substrate. The results showed that there is a good bond between substrate and coting layers and the continuous coating method is much more suitable for coating the surfaces of large sheets or plates safely and economically.
