摘　　要：Ti-1023钛合金整体框部件为Z形截面件,存在成形难度大、高温氧化严重、锻造温度范围窄、锻造变形抗力高、流动粘滞等问题,而现有钛合金防护润滑剂均难以满足要求。本文通过不同组分配比防护润滑剂的试烧,性能测试及工艺验证等试验,研制了适用于Ti-1023钛合金薄壁整体框部件等温超塑性锻造新型锻造防护润滑剂。该防护润滑剂配比为硼砂∶GL09∶粘结剂∶TiC=20∶80∶100∶8～10,涂敷厚度为0.08～0.14 mm。实践表明,新型防护润滑剂具有较好的防护润滑效果及长效工作能力。Ti-1023 is difficult to form components with Z sections due to the severe high-temperature oxidation,the narrow range of forging temperature and high deformation resistance,as well as viscous flow.The existed protective lubricants can not meet the requirement.The glass-base protective lubricant for the isothermal super plastic forging of Ti-1023 titanium alloy was investigated through heating tests,properties tests and technology tests.The proportion of this new protective lubricant includes∶borax∶GL09∶binder distributor∶TiC=20∶80∶100∶8-10;the coating thickness is 0.08-0.14 mm.The experiment illustrates that the new lubricant has beneficial effects of protection and long working capabilities.
