[14A-T2-04] Effect of Powder Metallurgy Raw Material Powder and Lubricant on Surface Condition
キーワード：Lubricant, surface texture, pores,
The relationship between the physical properties and the density of sintered materials has been known until now. In general, the required functions are being met by increasing the density of the sintered material. Powder metallurgy is characterized by the creation of pores on the surface and inside of the material, and are mainly caused by the burning of lubricant during the sintering process. Up to now, there has been little mention of parameters other than the area ratio of pores that are related to density. So this time, we observed how the raw iron powder and lubricant affect the surface condition of the sintered body.
