Fig. 1From: Improved Bond Strength of Cyanoacrylate Adhesives Through Nanostructured Chromium Adhesion LayersSEM images of bonding surfaces. SEM images of the substrates used for lap shear bonds with a the surface of an unmodified HDPE substrate, with a high-magnification inset where the scale bar is 5 μm, and b a prepared surface of 304 stainless steel, with a high-magnification inset where the scale bar is 5 μm. The HDPE surface has been prepared with 5 nm of gold deposited for SEM imagingBack to article page
