摘要： A method of anodizing includes immersing an aluminum alloy workpiece in a phosphoric acid anodizing solution and applying a voltage to form a porous oxide layer on the workpiece. The workpiece is then removed from the phosphoric acid anodizing solution and immersed in a controlled anodizing solution. A voltage is applied to form a dense oxide layer under the porous oxide layer. Dissolution of the porous oxide layer is controlled during the formation of the dense oxide layer by using tartaric acid in the controlled acid solution such that the thickness of the porous oxide layer is substantially equivalent before and after the formation of the dense oxide layer. The duplex anodized layer can be further sealed by soaking in a sealing solution to protect the porous oxide layer from hydrolytic decomposition, to improve corrosion protection, and to enhance the bonding with other structural components through adhesives.
摘要翻译：阳极氧化的方法包括将铝合金工件浸入磷酸阳极氧化溶液中并施加电压以在工件上形成多孔氧化物层。然后将工件从磷酸阳极氧化溶液中取出并浸入受控阳极氧化溶液中。施加电压以在多孔氧化物层下形成致密氧化物层。通过在控制的酸溶液中使用酒石酸，在形成致密氧化物层的过程中控制多孔氧化物层的溶解，使得多孔氧化物层的厚度在形成致密氧化物层之前和之后基本相同。双面阳极氧化层可以通过浸泡在密封溶液中进一步密封，以保护多孔氧化物层免于水解分解，改善腐蚀保护，并通过粘合剂增强与其它结构组分的粘结。

摘要： A flow battery includes a cell that has first and second flow fields spaced apart from each other and an electrolyte separator layer. A supply/storage system is external of the cell and includes first and second vessels fluidly connected with the first and second flow fields, and first and second pumps configured to selectively move first and second fluid electrolytes between the vessels and the first and second flow fields. The flow fields each have an electrochemically active zone that is configured to receive flow of the fluid electrolytes. The electrochemically active zone has a total open volume that is a function of at least one of a power parameter of the flow battery, a time parameter of the pumps and a concentration parameter of the fluid electrolytes.

摘要： A cooling system includes an electrocaloric element (12) having a liquid crystal elastomer or a liquid form liquid crystal retained in an elastomeric polymer matrix. A pair of electrodes (14.16) is disposed on opposite surfaces of the electrocaloric element. A first thermal flow path (18) is disposed between the electrocaloric element and a heat sink (17). A second thermal flow path (22) is disposed between the electrocaloric element and a heat source (20). The system also includes a controller (24) configured to control electrical current to the electrodes and to selectively direct transfer of heat energy from the electrocaloric element to the heat sink along the first thermal flow path or from the heat source to the electrocaloric element along the second thermal flow path.
