【摘要】 为了评价涂料的绝热性能，利用自制装置测定了不同浇注速度和不同浇注时间条件下涂层的温度变化，从而计算出涂料的热物性，为复杂薄壁铝合金铸件的生产提供了科学依据更多还原

【Abstract】 A test device was developed to assess the insulating properties of coatings in this paper.It can be used to test the temperature varies of coating layers under different pouring speed and time,and the thermal property parameters can be calculated out,which can be applied to the production of complex,thin wall aluminium castings.更多还原
