    摘要： Processes and systems for formation of high voltage, anodic oxide on a valve metal anode. The processes generally includes immersing a valve metal anode in an electrolyte forming bath comprised of a formation electrolyte, performing an anodization step; and maintaining or regulating the temperature of the formation electrolyte accurately at a temperature at or below 40° C. during the anodization step. The anodization firstly under constant current until a target potential is reached and secondly under constant potential at the target potential until the current falls below a predetermined termination current level. The systems generally include a tank configured to receive one or more anodes in an electrolyte forming bath comprised of a formation electrolyte; and a subsystem for cooling and maintaining the formation electrolyte at the desire processing temperature. The systems may further include electronic controls for monitoring and adjusting system or process parameters.

    摘要翻译： 在阀金属阳极上形成高电压，阳极氧化物的工艺和系统。 该方法通常包括将阀金属阳极浸入由地层电解质组成的电解质形成浴中，进行阳极氧化步骤; 并且在阳极氧化步骤期间，在等于或低于40℃的温度下，精确地维持或调节地层电解质的温度。 首先在恒定电流下进行阳极氧化，直至目标电位达到目标电位，其次在目标电位下达到恒定电位，直至电流下降到预定的终止电流水平以下。 所述系统通常包括：配置成在包含地层电解质的电解质形成浴中接收一个或多个阳极的罐; 以及用于在所需加工温度下冷却和保持地层电解质的子系统。 该系统可以进一步包括用于监视和调整系统或过程参数的电子控制。
