CrxNy coatings prepared by magnetron sputtering method
Original language description
Chromium nitride coatings were deposited by reactive magnetron sputtering onto substrates made from Cr-ledeburitic steel 1.2379. Microstructures, phase constitution, mechanical and tribological properties of CrN-coatings were investigated. It has been found that the deposition at given combination of parameters gave dense, fine-grained coatings, having columnar structure and very smooth surface. The coatings were formed from Cr2N when low N-2 : Ar ratio has been used while they contained CrN at higher nitrogen input into the processing chamber. The Young's modulus of the coatings was influenced only slightly by the deposition conditions. On the other hand, the hardness of the CrN was higher than that of the Cr2N. The adhesion of the CrN is better thanthat of Cr2N. The principal explanation is that the Cr2N is brittle in nature and exhibits a strong tendency to cracking and spallation when normally loaded. Generally, the friction coefficient measured against 100Cr6 ball bearing steel w
