摘要：

In this study, we explore the use of atmospheric pressure plasmas for enhancing the adhesion of SiC surfaces using a urethane adhesive, as an alternative to grit blasting Surface analysis showed that He-O-2 plasma treatments resulted in a hydrophilic Surface mostly by producing SiOx. Four point bending tests and bonding pull tests were carried out on control, grit-blasted, and plasma-treated surfaces. Grit-blasted samples showed enhanced bonding but also a decrease in flexural strength. Plasma treated samples did not affect the flexural strength of the material and showed an increase in bonding strength. These results suggest that atmospheric pressure plasma treatment of ceramic materials, is an effective alternative to grit blasting for adhesion enhancement.
