Four model plasma coatings obtained with selected parameters and precursors (acetylene, acrylic acid, and maleic anhydride) were developed for the preparation of adhesive joints of a metal/elastomer assembly. One of these layers, pulsed wave (PW), is thin and highly functionalized, while another continuous wave (CW) coated with the same thickness is less functionalized but crosslinked. The other two layers (CW × 2, CW + PW), twice as thick compared with PW and CW, show the same chemical criteria. The adhesion strength of prepared assemblies is increasing, but mostly depends on the precursor type. Moreover, such model layers allow to study the adhesion mechanism between the metal and the elastomer. The thermodynamic adhesion, that is, surface energy closer to the elastomer one, appears to prevail.

用于增强金属/弹性体组件粘合力的等离子体聚合物

开发了使用选定参数和前体（乙炔、丙烯酸和马来酸酐）获得的四种模型等离子涂层，用于制备金属/弹性体组件的粘合接头。其中一层脉冲波 (PW) 很薄且高度功能化，而另一层涂覆有相同厚度的连续波 (CW) 功能化程度较低但已交联。其他两层 (CW × 2, CW + PW) 的厚度是 PW 和 CW 的两倍，显示出相同的化学标准。准备好的组件的粘合强度正在增加，但主要取决于前体类型。此外，这种模型层允许研究金属和弹性体之间的粘附机制。热力学粘附，即更接近弹性体的表面能，似乎占主导地位。
