摘要：
(Ti,V)N coatings were deposited on WC-Co substrates using the cathodic arc ion plating method. The structures and compositions were characterized by X-ray diffraction, transmission electron microscopy, and electron probe microanalysis. The (Ti,V)N coating showed a single phase cubic B1 structure with a dense columnar microstructure typical of cathodic arc ion plating. The wear-resistant properties and friction coefficients of (Ti,V)N coatings against steel were evaluated using the ball-on-disc test at elevated temperatures. (Ti,V)N had a friction coefficient of 0.51 against carbon steel at 600 degrees C, which is lower than the 0.91 friction coefficient of (Ti,Al)N. High-speed cutting performance was investigated using coated carbide endmills. (Ti,V)N coatings showed greatly improved cutting performances on low hardness carbon steels. The wear mechanism and cutting characteristics are discussed in terms of the structure and properties of the films. (c) 2005 Elsevier B.V. All rights reserved.
