Effect of Chromium carbide to microhardness and life time of the screw blade during PTA welding Durmat 506 powder alloys Abstract: Nowaday, the welding process which creates a hard surface and improves the abrasion resistance of the hammer mill is an urgent requirement. Microstructure and microhardness are influence to abrasion resistance and impact of the weld. There are factors determine to life time of hammer mill. In this paper, the microstructure, hardness and abrasion resistance, which will be analyzed and evaluated the surface quality of hammer mills in the bricks and tiles. The PTA (Plasma Transferred Arc) welding process by Durmat 506 powder alloys was used to surface of the hammer. Metallography method was used to analyzed microstructure, microhardness and abrasion tested by theory and experimental. Keywords: Microstructures, microhardness, PTA, welding hardsurfacing, abrasion. |
