摘要： PROBLEM TO BE SOLVED: To provide a method of producing an iron based powdery mixture for powder metallurgy in which the segregation of additives such as a lubricant, graphite powder and copper powder and the occurrence of dust are reduced, the change in fluidity with the lapse of time is reduced, and the variation of apparent density is extremely little. SOLUTION: Fatty acid which is liquid at an ordinary temperature is added to iron based powder, and primary mixing is performed. Powder for an alloy and metallic soap are added thereto, and secondary mixing is performed. The temperature is raised in the process of the secondary mixing or after the secondary mixing to produce a co-melt of the fatty acid and the metallic soap. Next, cooling is performed while conducting third mixing, and the co-melt is cooled to solidify. The powder for an alloy is stuck to the surfaces of the iron based powder particles by the bonding force of the co-melt. Metallic soap or wax, and an antistatic agent of 0.01 to 0.1 wt.% are added at the cooling, and fourth mixing is performed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an iron-based powdery mixture with which machinability of a sintered compact can be improved without bringing about deterioration in its mechanical properties. SOLUTION: The iron-based powdery mixture is obtained by mixing iron-based powder with powder for alloy, powder for improving machinability and further, a lubricant. As the powder for improving machinability, manganese sulfide powder with the average particle diameter of 1 to 60 μm and/or calcium fluoride powder with the average particle diameter of 1 to 60 μm is used. The powder for improving machinability is comprised by 0.1 to 1.5 mass% to the total content of the iron-based powder, the powder for alloy and the powder for improving machinability. Further, the powder for improving machinability has a grain size distribution similar to the grain size distribution of holes in an iron-based sintered compact obtained by subjecting an iron-based powdery mixture mixed with iron-based powder, powder for alloy and a lubricant to pressure-compacting and sintering. In this way, the holes in the sintered compact can be reduced, intermittent impact to a tool is reduced, and the service life of the tool is prolonged. Further, a part or the whole of the iron-base powder can be used as the iron-based powder applying a segregation-preventive treatment, in which the powder for alloy and/or the powder for improving the machinability, are stuck on the surface with a binder.
