本文测定了不同初始温度的al2o3陶瓷在室温水浴淬火后的表面传热系数。采用多点测温技术和反热传导法，测定了该系数随水淬过程中陶瓷表面温度的变化规律。结果表明，表面换热系数不仅与淬火初始温度及其在淬火介质中的演变有关，还与试样尺寸有关。此外，对以往传热与热应力研究中传统方法将表面传热系数作为材料与淬火介质的联合常数的合理性进行了简要讨论。
In this paper, we determined the surface heat transfer coefficient of Al2O3ceramics quenched from different initial temperatures into a water bath at room temperature. By using the multipoint temperature measurement technique and the inverse heat conduction method, this coefficient was measured as function of surface temperature of the ceramics during the water quench. The obtained results indicate that the surface heat transfer coefficient largely depends not only on the initial quenching temperature and their evolution in quenching media but also on the sizes of tested specimens. In addition, brief discussion was completed on the rationality of the traditionally used approach, which considers the surface heat transfer coefficient as a joint constant of materials and quenching media, in previous studies on heat transfer and thermal stresses.
