WebJul 25, 2024 · The mechanical theory focuses on interlocking between adhesive and a rough substrate surface. Again good wetting is required, or surface roughening is likely to lead to poor bond strength. It has been shown to apply to some surfaces rough on a macroscale as well as to microfibrous and microporous surfaces, such as anodized aluminum. WebDec 11, 2013 · Mechanical Interlocking: The mechanical interlocking theory of adhesion states that good adhesion occurs only when an adhesive penetrates into the pores, holes and crevices and other irregularities of … WebAug 14, 2024 · Several studies have been carried out in an effort to overcome the adherence challenge. The studies have shown that the roughness of the surface has an effect on adhesion force. Adhesion of the polymers to rough surfaces is based on the mechanical interlocking theory.
