文章主要针对金属结合剂自锐性差,树脂结合剂耐热性差的缺点,研发一种低温烧结复合型的金属-树脂结合剂。结合剂以铜粉、锡粉、锌粉、铅粉、银粉、树脂粉等为原料,先冷压成型,再热压烧结,当树脂含量为10%,温度460℃时,样条的硬度值达83.4HRB,强度值达145.5 MPa。最佳烧结工艺:温度460℃,保温时间1分钟,压力为0.5MPa。
The article mainly aims at the poor self-sharpening of the metal binder and the poor heat resistance of the resin binder, and has developed a low-temperature sintered composite metal-resin binder. The binder is copper powder, tin powder, zinc powder, lead powder, silver powder, resin powder and the like, and is first cold-formed and then hot-pressed. When the resin content is 10% and the temperature is 460 ° C, Reaching 83.4HRB, the intensity value reached 145.5 MPa. The best sintering process: temperature 460 ℃, holding time 1 minute, the pressure is 0.5MPa.
