摘要
为进一步改善铁基金属结合剂的性能,以Cu-Ce合金、铁、锡、铜等为原料,采用热压烧结法制备金属结合剂,研究Cu-Ce合金对结合剂性能的影响。结果表明:随Cu-Ce合金粉质量分数的增加,铁基金属结合剂的密度、抗冲击强度均逐渐增加,而抗弯强度和洛氏硬度则表现出先增大后减小的趋势。当Cu-Ce合金的质量分数为8%时,洛氏硬度(HRB)达到最大;Cu-Ce合金的质量分数为6%时,抗弯强度最大,为518.12 MPa。在铁基金属结合剂中添加Cu-Sn合金粉会降低其各项力学性能。
To further enhance the property of Fe-based metal bond, Cu-Ce alloy, Fe, Sn and Cu used to prepare different types of metal bond by hot pressing, thus studying the effect of Cu-Ce alloy property of the bond. The results show that density and impact strength of the bond increase as content of Cu-Ce alloy increases, while the bending strength and Rockwell hardness increase and decrease. It is concluded that HRB reaches its top value when the mass fraction of Cu-Ce alloy is are on the then 8%, and that the bending strength increases to its maximum, namely 518.12 MPa when Cu-Ce mass fraction is 6 %. It is also found that adding Cu-Sn alloy reduces mechanical property of Fe-based metal bond
