摘要
采用粉末冶金工艺替代机械加工工艺,通过分析产品结构,精选材料配方,优化控制模具模架设计、温模压制成形、高温烧结、精密整形及达克罗等工艺,制备出了高质量的ABS感应齿圈成品零件,并对其进行力学性能测试。结果显示,材料组份为Fe–0.8Ni–3Co–0.2P的ABS粉末冶金感应齿圈成品密度为7.15 g·cm^-3,表面硬度HRB 55,抗拉强度421 MPa,饱和磁感应强度1.12 T,中性盐雾试验240 h无锈蚀。结果表明,ABS粉末冶金感应齿圈技术性能指标完全满足新能源汽车制动控制系统应用要求,用户装机使用运行效果良好。
Instead of the mechanical processing technology,the high quality ABS induction gear ring parts were manufactured by powder metallurgy technology through studying the product structure,optimizing the material constitute,and controlling the mold design,thermoforming,high temperature sintering,precision shaping,and Dacromet technology.The mechanical properties of the ABS powder metallurgy induction gear ring were tested.In the results,the Fe–0.8Ni–3Co–0.2P ABS powder metallurgy induction gear ring products show the density of 7.15 g·cm^-3,the surface hardness of HRB 55,the tensile strength of 421 MPa,the saturation flux density of 1.12 T,and no corrosion for 240 h in the neutral salt spray test.The performance index of ABS powder metallurgy induction gear ring fully meets the application requirements of the new energy vehicles,showing the good operation effect.
