聚晶金刚石复合片钎焊基础研究

Indexed by:Journal Article

Date of Publication:2005-08-30

Journal:金刚石与磨料磨具工程

Included Journals:Scopus、ISTIC、PKU

Issue:4

Page Number:25-28

ISSN:1006-852X

Key Words:PCD复合片;钎焊;硬质合金

Abstract:通过对聚晶金刚石(PCD)复合片的热稳定性研究,总结出其钎焊的安全温度:在空气气氛下,钎焊SYNDITE PCD复合片时,CTB002的钎焊安全温度应低于650℃,CTB010应低于670℃,CTB025应低于720℃.在钎焊安全温度范围内通过四种钎料(编号1#-4#)对硬质合金的润湿性试验,优选出PCD复合片与硬质合金之间实施钎焊的最佳钎料为3#(Ag50%,Cu 15.5%,Zn 15.5%,Ni+Co 3%,Cd 16%),其他钎料对硬质合金的润湿性明显低于3#.另外通过分析硬质合金中不同成分(碳化物WC、TiC、TaC、NbC和粘结剂Co)的钎焊性能,总结出钎焊PCD复合片应选用Co含量高的WC基硬质合金.
