Sintered, iron-based material with improved machinability
With alloying of ZhGr1D3 material with molybdenum and sulfur by the addition to the charge of 1.5% molybdenum disulfide in place of zinc stearate lamellar sulfides and oxysulfides are formed in the structure in place of hard oxides, which provides an improvement in the machinability of the sintered material as a result of a decrease in impact loads on the cutting tool. The ZhGr1D3M1K0.5 material obtained as a result of such alloying presses better and has higher strength properties than ZhGr1D3 material obtained as a result of such alloying presses better and a higher strength properties than ZhGr1D3 material with the same level of plasticity, hardness, and corrosion resistance.
