摘　　要：为了给钛合金的模锻工艺制定提供理论依据，利用稳态法在自制的接触热阻测量装置上研究了玻璃润滑剂对TA15钛合金与模具用K403镍基高温合金界面接触热阻的影响。结果表明：在TA15和K403合金接触面间加入玻璃润滑剂可显著增大两者间的接触热阻；当界面平均温度不超过636℃，玻璃润滑剂厚度在0．06～0．96mm范围内时，TA15与K403合金界面接触热阻与玻璃润滑剂厚度大致呈线性关系；TA15与K403合金的界面接触热阻随着温度的升高及压力的增大而减小。In order to provide theoretical basis for the forging process of Ti alloy, an experimental study for examining thermal contact resistance（Rt）of TA15 （Ti alloy）/glass lubrication/K403 （Ni base alloy） joint was carried out by using steady heat flow method with a set of self-developed thermal contact resistance experimental system. The results show that glass lubrication had a great adiabatic characteristic. R, was linear with the thickness of glass lubrication when the thickness of glass lubrication changed from 0. 06 to 0. 96 mm and the temperature of the joint was below 636 ℃. Rt of TA15/glass lubrication/K403 decreased with increasing pressure and temperature
