Abstract

本发明公开一种铜包铁(Fe-20wt%Cu)基刹车材料的制备工艺,从提高基体强度和刹车性能的角度考虑,以铜包铁(Fe-20wt%Cu)粉为基体添加润滑组元MoS2和片状石墨、摩擦组元SiC、强化组元Al和Ni,合金组元Mn和Cr,通过感应加热烧结和燃烧反应合成方法制备出了铜包铁(Fe-20wt%Cu)基刹车材料,具体工艺步骤如下:钢背加工;称量粉末;混料;压制;烧结;冷却;试样清洗;性能测试;基体晶粒越细小刹车材料的抗压强度越高,孔隙率越小刹车材料的抗压强度越高,磨损率越小;本发明所述的铜包铁(Fe-20wt%Cu)基刹车材料制备方法工艺合理、易于控制,制备的刹车材料具有热强度高、摩擦系数稳定、磨损率小和成本低的特点。
The invention discloses a preparation technology of a Fe-20wt%Cu based brake material. In consideration of the improvement of the base strength and the brake performance, Fe-20wt%Cu powder is adopted as a base and is added with a lubricating component containing MoS2 and flake graphite, a friction component SiC, a reinforcing component containing Al and Ni and an alloy component containing Mn and Cr, and the Fe-20wt%Cu based brake material is prepared through the induction heating sintering and combustion reaction synthesis method. The preparation technology comprises the following specific steps: steel backing processing, powder weighing, mixing, pressing, sintering, cooling, sample cleaning, and property testing. The smaller the crystal particles of the base are, the higher the compressive strength of the brake material is; the smaller the porosity is, the higher the compressive strength of the brake material is, and the smaller the wear rate is. The preparation method of the Fe-20wt%Cu based brake material is reasonable in process and easy to control, and the prepared brake material has the characteristics of high thermal intensity, stable friction coefficient, small wear rate and low cost.
