In this study, iron-lubricant mixed powders were made with the dry mixing device to give mechanical energy and plasma (NC method) and ball mill (BM method), and the effects of mixing method on adhesion state of lubricant, powder characteristics, ejection force, green density and green strength were investigated. As the result, in the NC method, the lubricant evenly bonded the surface of iron powder, and it was effective for lowering of ejection force and improvement of green density. In the BM method, the lubricant bonded on the craters of iron powder, and it was effective for improvement of powder characteristics and green density.
