A low-cost precision casting method for titanium alloy and titanium-aluminum alloy
InactiveCN102294436AIncrease contentControl quality costFoundry mouldsFoundry coresPolyvinyl alcoholTitanium alloy
The invention relates to a method for precisely casting a titanium alloy and a titanium aluminum alloy with low cost, which relates to a method for precisely casting the titanium alloy and the titanium aluminum alloy, and solves the technical problem that cast pieces have low surface quality and internal quality in the conventional method for lowering the cost of precisely casting the titanium alloy and the titanium aluminum alloy by using electrically-fused alumina and silica sol. The method comprises the following steps of: preparing a surface layer binder from zirconium sol, silica sol, a wetting agent JFC, n-octyl alcohol, polyvinyl alcohol and latex; adding calcium carbonate, alumina, titanium dioxide and zirconia to prepare a surface layer coating; preparing a shell surface layer; preparing a shell back layer by a universal method for precisely casting the titanium alloy; dewaxing and sintering to obtain a shell; and casting the titanium alloy or the titanium aluminum alloy by using the shell so as to obtain a titanium alloy cast piece or a titanium aluminum alloy cast piece. Compared with a precise casting method by purely using a zirconium-based binder and a zirconia fireproof material, the method has the advantage that raw material cost is lowered by 30 to 70 percent and the method can be used for civil titanium alloy cast pieces and titanium aluminum alloy cast pieces for common aviation.
