水淬試樣在190的時效溫度下有最高的阻尼性能,通過與爐冷試樣的阻尼性能(五種熱處理制度爐冷試樣的阻尼性能較高)對比發現,在溫度低於120 、高於290范圍,水淬試樣在190時效溫度下的阻尼性能均高於爐冷試樣的阻尼性能,在120 290之間,它的阻尼性能低於爐冷試樣的阻尼性能,而此溫度區間正好是位錯內耗峰出現的溫度范圍。Practice heating test of spread sample has been underway and contrasted with traditional electric furnace. production technology, structure and property of the coating have been studied in order to search for a. new technology method with not only enhancing thermal conductivity of coating but also dropping its electrical conductivity and reducing its production cost
