Zusammenfassung: | In the present work formation of welded layer by using powder of cheap elements was investigated. Chromium and ferrosilicon were chosen for this purpose. These elements dissolve in the ferrite and increase it strength and hardenability. Because of metal high heat conductivity the layer becomes hardened after welding. So full heat treatment isn't necessary, and for the stress relieving low annealing can be used. For minimising of wear, graphite powder was added to the deposit powder. Carbon with above mentioned elements makes up carbides. That's the reason why deposit layer become high wear resistant. Thickness of deposited layer 2 - 2.5 mm doesn't change the geometrical parameters of initial component or detail. |
