Abstract
- The thermal contact conductance of metallic interfaces depends upon the thickness of vapor deposited multiple-layered coatings. A study of aluminum 6061-T6 with indium coatings shows that the conductance enhancement factor approaches a maximum asymptotically for an optimum coating thickness. Oxidation and thermal cycling cause poor layer adhesion in multiple layer coatings. This results in very low conductance enhancement factor, as compared to a single layer coating of the same thickness. A theoretical study predicts the maximum level of enhancement.
