穿梭传热是影响斯特林发动机性能的主要原因之一。这项研究是关于减少穿梭热传递涂层置换。在伽马型斯特林发动机的置换器上涂覆一层氧化钇稳定的氧化锆（YSZ），通过比较涂覆和未涂覆置换器的发动机转速-功率和转速-扭矩特性，评价涂层对发动机性能的影响。获得了700、800和900°C加热器温度的特性。在加热器温度的每个阶段，充气压力范围为1至3.5巴，增量为0.5巴。在900°C加热器温度和3巴充气压力下，涂覆前轴功率为34.9W，涂覆后功率增加至43.8W，这对应于25%的增量。施加到发动机上的温度没有对涂层造成任何损坏。版权所有© 2008约翰威利父子有限公司。
The shuttle heat transfer is one of the reasons reducing the performance of Stirling engines. This study is concerned with the reduction in shuttle heat transfer by coating the displacer. The displacer of a gamma type Stirling engine was coated with a layer of yttria‐stabilized zirconia (YSZ), and the effect of the coating on the engine performance was evaluated by comparing speed‐power and speed‐torque characteristics of the engine with coated and uncoated displacers. Characteristics were obtained for 700, 800 and 900°C heater temperatures. At each stage of the heater temperature, the charge pressure ranged from 1 to 3.5 bars with 0.5 bar increments. At 900°C heater temperature and 3 bars charge pressure, the shaft power before coating was 34.9 W, after coating the power increased to 43.8 W, which corresponds to a 25% increment. The temperature applied to the engine did not cause any damage on the coating layer. Copyright © 2008 John Wiley & Sons, Ltd.
