实验表明，用PVD法制备的氮化铬和碳氮化铬多层膜的耐磨性均高于各相。采用阴极弧蒸发法制备了CrN/CrCN多层膜，由7个模组组成，每个模厚约400 nm，分别代表了不同模数下CrN和CrCN层的厚度比。以0.1微米厚的铬层作为底层，用划痕试验和洛氏硬度和洛氏试验测定了涂层的附着力，测定了用于木材的硬度、应力和摩擦磨损系数。对干木进行了工业铣削试验多层CrN/CrCN涂层刀具与木材表面的结合力较好(约115N)，磨损率较低。与未涂层刀具相比，多层CrN/CrCN涂层刀具提高了木材表面的质量(C)2010 Elsevier B V版权所有
The performed experiments revealed that the anti-wear resistance of chromium nitride and chromium carbonitride multilayer coatings obtained by the PVD method was higher than each of the phases separatelyThe CrN/CrCN coatings were obtained using cathodic arc evaporation They consisted of seven modules each approximately 400 nm thick characterised by different thickness ratio of the CrN and CrCN layers in the modulus A layer of chromium 0 1 mu m thick was used as a sublayer The adhesion of the coatings was determined using scratch test and Rockwell test Hardness and stress as well as friction and wear coefficients when used to work timber were determined Industrial milling tests of dry wood were carried out The results of above measurements showed that the best useful properties were observed when the thickness ratio in coatings module was 2 1 which could be attributed to its very good adhesion to the substrate (about 115 N) and low wear rate The tools with multilayer CrN/CrCN coatings improve the quality of the treated wood surface in comparison with uncoated knives (C) 2010 Elsevier B V All rights reserved
