Enhancement of Corrosion and Wear Resistance in Polymeric Coatings via Ce(III)‐Functionalized Ternary ZnAlCe Layered Double Hydroxides Intercalated With EDTMP

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The intricate corrosion environment necessitates the polymeric coating's adaptability to the surroundings. In this work, the integration of rare‐earth Ce(III) ions and ethylene diamine tetramethylene phosphonic acid (EDTMP) in a layered double hydroxide (LDH) material is developed to enhance the corrosion protection and anti‐wear properties of

氧化锌电阻脉冲Ⅴ-Ⅰ特性方程在避雷器中的应用

open access: yesDianci bileiqi, 2013
文献提出了一种适用于氧化锌非线性元件的特性方程和测定该方程式常数的方法,它能在电流峰值变化2~3个数量级的范围内,正确地表达电阻片的实际特性,其准确度与电流/电压测试值的准确度相当。我们用文献[1]的方法,对温州某公司的各种避雷器电阻片进行了8/20脉冲Ⅴ-Ⅰ特性方程的验证试验,试验结果证明了它的适用性,并给出了验证试验的结果,同时报道了在验证试验中所发现的以往未知的一些物理现象,据此,可以进一步提高电阻片的保护特性。
