A microblasting treatment carried out on CrN coated samples was studied to investigate the induced effect on corrosion and wear resistance. CrN coating was deposited through Cathodic Arc Evaporation technique on quenched and tempered steel. The properties of the coating were studied by hardness measurements, scratch, potentiodynamic, and pin-on-disk tests. The results show that microblasting reduces the corrosion resistance while improving the wear behavior.

Crn Coatings

TiN/CrN nanoscale multilayered coatings have been deposited using cathodic arc evaporation system. The coatings were deposited using one Ti target and one Cr target with a fixed power output in the processes, whilst the bi-layer thickness was varied by rotation of the substrate holder to obtain different nanoscale multilayered period thickness. The texture structure, residual stress and nanoscale multilayer thickness of the coatings were determined by X-ray diffraction using both Bragg-Brentano and glancing angle parallel beam geometries. Hardness and adhesion strength of the coatings were measured by Vicker's and Rockwell-C indentation methods. It has been found that the structural and mechanical properties of the films were correlated with nanoscale bi-layer thickness and crystalline texture. The maximum hardness of nanolayered TiN/CrN multilayer coatings was approximately 28 GPa, which the bi-layer thickness was 4 nm.

Protective coatings with different compositions of Fe, Cr, and Al were deposited by cathodic arc evaporation method on fragments of Zr1Nb alloy fuel claddings. The influence of the composition and structural state of the developed coatings on their physical and mechanical properties (microhardness, resistance to corrosion and cavitation and abrasive wear) has been studied. It is shown that the optimal combination of mechanical properties and high resistance to oxidation from a series of studied coatings FeCr, FeCrAl, and CrAl have coatings of the FeCrAl system with a concentration of Cr ~ 22 at.% and Al ~ 14.3 at.%. It was found that protective coatings such as FeCr, FeCrAl, and CrAl with a thickness of ~ 12 μm significantly increase the resistance to oxidation and prevent the destruction of fuel claddings under oxidation in air at a temperature of 1150 °C for 1 h.

Crn Coatings

TiAlN, and TiAlN/CrN nanolayered coatings were synthesized by cathodic-arc evaporation with plasma enhanced duct equipment. Chromium and TiAl (50/50 at %) alloy cathodes were used for the deposition of TiAlN/CrN coatings. The effects of bilayer thickness and chromium content on the microstructure and mechanical properties of TiAlN/CrN nanolayered coatings were studied. The preferred orientation was changed from (200) in TiAlN monolayered coatings to (111) plane in the multilayered TiAlN/CrN coatings. The multilayered TiAlN/CrN coating with periodic thickness of 20 nm and the smallest crystallite size of 28 nm exhibited the highest hardness of 39 GPa. The multilayered TiAlN/CrN coatings also showed the best adhesion strength using scratch tests. It has been found that the structural and mechanical properties of the films were correlated with the addition of chromium and nanolayer thickness.
