Tribologie (technologie)Index. décimale : 668.4 Plastiques, vinyles Résumé : The adhesion tendency of the polymers polyoxymethylene , polyamide 6.6 and polyether ether ketone against hard coatings to protect molds in polymer processing was evaluated by a combination of tribological tests, investigations of wear tracks and measurements of the coatings’ surface energies. It was found that a low surface roughness and a low surface energy of the coating are beneficial to reduce friction and adhesion tendency. Among the coating materials investigated, CrN seems to be the most promising candidate for the protection of molds for polymer processing.

Revêtement métalliqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Coatings of CrN and CrC were deposited on a YT14 cemented carbide cutting tool using cathodic arc ion plating (CAIP). The surface and interface morphologies of the as-obtained CrN and CrC coatings were analyzed using a field emission scanning electron microscope. The heights, particle diameters and power spectral densities of CrN and CrC coatings were analyzed using atomic force microscopy and the correlated parameters of roughness were obtained. The results show that the roughness of the CrN and CrC coatings is 81.7 × 10−3 and 70.2 × 10−3 nm, respectively, and CAIP has little effect on the CrN and CrC coating roughness. The height of the peak values of CrN and CrC coatings is 0.498 and 0.502 nm, respectively, and the reduction friction of the CrN coating was slightly better than that of the CrC coating. The average particle diameter of the CrN and CrC coatings is 6.575 × 102 and 7.678 × 102 nm, respectively, and the particles are uniformly distributed with no large-scale fluctuations. The power between the cursors of the CrN and CrC coatings is 1.44 × 10−2 and 9 × 10−3 nm2, respectively, with the power spectral density of the CrN coating being the dominant frequency.
