Abstract: PURPOSE:To improve wear resistance by sintering the layers of the 1st and 2nd alloy powder sheets contg. respectively specific weight % of an acrylic binder, Fe-Cr alloy powder and eutectic alloy powder at a prescribed temp. on the surface of a metallic base body. CONSTITUTION:The 1st alloy powder sheet contg. 94-99% Fe-Cr alloy powder and 6-1% acrylic binder and the 2nd alloy powder sheet contg. 94-99% eutectic alloy powder and 6-1% acrylic tacky binder are formed by pressing, coating, etc. on the surface of a metallic base body. The sheets are then heated and sintered in a non-oxidative atmosphere kept at the temp. higher than the solidus line temp. of the eutectic alloy and lower than the solidus line temp. of the Fe-Cr alloy. The eutectic alloy component infiltrating into the pores of the Fe-Cr alloy layer reacts with Fe-Cr to create composite carbide which contributes to an increase in wear resistance. The eutectic alloy entering the pores decreases considerably the shrinkage of the sheet.

IPC: H01M4/84
Filed: 1991-02-28
Abstract: PURPOSE:To prevent a gate for molten metal supply from being choked up by solidifying substances of the molten metal to increase the number of cast products by forming a recessed part in the reverse direction side to the rotary direction of a rotary casting mold relative to the gate for molten metal supply. CONSTITUTION:A rotary casting mold 10 rotates in the direction of an arrow F around a driving shaft 11 as a center by a driving motor. A recessed part 7 is formed in the bottom wall part 20e of a molten metal supplying part 20 in the reverse direction to the rotary direction F of the casting mold 10 relative to a gate 50. The recessed part 7 is so formed as to open to a contacting surface 20f along the gate 50. The molten metal enters the recessed part 7 and solidifies inside and the recessed part prevents solidified substances 60 from moving. The solidified substances 60 are not conveyed to the gate 50 side and remain near the recessed part 7 even when the casting mold 10 rotates continuously. Consequently, molten lead alloy is prevented from flowing in the grooved part 10c which is in the reverse direction to the rotary direction F of the casting mold 10.
