 Full text | Abstract: Continuous hard protective layers on soft substrates working under elastic deformation conditions are prone to uncontrolled cracking and detaching from the substrate during bending and straining. Implementation of a noncontinuous hard pattern deposited on the surface allows such an antiwear layer to freely deform with the substrate. The idea was demonstrated for patterns made of regularly spaced, micrometer range sized nanocomposite islands. The nanocomposite used consisted of an epoxy resin matrix and superhard silicon carbide nanoparticles as a reinforcing component. Good dispersion of nanoparticles in the matrix was verified by means of atomic force microscopy. The significant improvement in wear resistance was measured under an applied load in the millinewton range using a custom-made microtribometer, and in the newton range using ball-on-disk apparatus. Such a system can be applied in textile machines and elastic yarn tensioners for damping the longitudinal component of vibrations, largely influencing the quality of the fabric obtained. the sp |
