Experiment research on the thermal contact conductance during the solid plastic forming

Journal: JOURNAL OF PLASTICITY ENGINEERING

Keyword:  接触换热系数影响因素实验研究;
Abstract: 文章通过自制的接触换热系数测量设备对纯铜与3Cr2W8V合金钢、不锈钢与不锈钢间的接触换热系数进行了实验研究.分析了温度和载荷对接触换热系数的影响,并且分析了在铝合金和模具钢的接触面间加入玻璃润滑剂后对接触换热系数的影响.实验结果发现,接触换热系数与温度的关系并不是简单的正比关系,而与载荷的指数近似成正比关系,且在接触而涂上玻璃润滑剂后,接触换热系数可大大降低.
