    • A method is provided for enhancing corrosion resistance of a metal surface that includes the step of forming a sol-gel coating in which nanostructured zinc phosphate (Zn3(PO4)2) and zinc oxide (ZnO) phases are present in the mixture. The method may include the steps of mixing an organosilane, organometallic, organic acid, water, and alcohol, and allowing the components of the mixture to partially hydrolyze, followed by adding at least one component having zinc functionality and at least one component having phosphate functionality to the partially hydrolyzed mixture, wherein the zinc component and phosphate component are added in a molar ratio of from about 1.5:1 to about 5:1 (Zn:PO4). The resulting mixture can be applied as a coating to a metal surface to improve the corrosion resistance of the metal and to enhance the adhesion of resinous materials to the metal surface.

    • Methods, systems, and articles of manufacture consistent with the present invention provide for determining the environmental resistance of a wire insulation. The broadband impedance of the wire is obtained before and after the wire is exposed to an environmental condition. The real and imaginary components of the dielectric functions are then extracted from the broadband impedances. A tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire prior to exposure is compared to a tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire after to exposure. The two tangents are then compared to determine the environmental resistant of the insulation.
    • 与本发明一致的方法,系统和制品提供确定电线绝缘体的耐环境性。 在电线暴露于环境条件之前和之后获得电线的宽带阻抗。 然后从宽带阻抗中提取介电函数的实部和虚部。 将暴露之前的线的介电函数的虚分量与实分量的比值的切线与曝光后的线的介电函数的虚分量与实分量的比的切线进行比较。 然后将两个切线进行比较,以确定绝缘体的耐环境性。
