“…Indeed, the wear resistance of WC based cemented Fig. 8 Secondary electron images at magnifications 2,000 (a) and 10,000 (b) of wear debris derived from grade-C cemented carbide, slid against WC-Co pins carbides generally increases with improved hardness and/or reduced carbide grain size and decreased binder volume fraction [4,[15][16][17][18][19][20][21][22][23]. One method for grain size refinement is the addition of small amounts of grain growth inhibitor, such as Cr 3 C 2 and/or VC, during liquid phase sintering [39,40].…”

“…Despite competition from pure engineering ceramics, WC cemented carbides are widely employed in tribological applications such as cutting tools [3][4][5], metal forming [6], mining [7], drilling [8] and machining [9,10], and even in the domain of aerospace [11,12]. An expanding trend in the development of these materials is grain size refinement towards nanometric scale and more narrow grain size distributions, which is found to result in higher hardness and improved wear resistance [13][14][15][16][17].…”

“…The dominant wear mechanism was adhesive and delamination wear. 10 The friction coefficient of WC-Co and (W, Ti)C-Ni coatings against 1044 grade steel varies in the range of 0.3-0.5 and 0.3-0.6, respectively, under sliding velocity of 4 ms −1 and normal load of 4.9 N. 11 Cadenas et al observed that the lubricated wear rate of AISI 1043 steel is 50-300 times as high as that of the WC-Co plasma sprayed coatings. 12 In one of our recent work, the fretting wear properties of TiCN-WC-Ni cermet with varying WC content (0-25 wt.%) is studied and the observed friction value varies within the range of 0.3-0.38.…”

“…112, bajo estas condiciones de ensayo, todos los materiales presentan una elevada resistencia al desgaste. Todas las tasas de desgaste se encuentran en el orden de 10 -7 mm 3 / N.m. La resistencia al desgaste de los materiales es considerada una función del tamaño de grano de WC, el contenido y distribución de la matriz de Co y la fuerza adhesiva entre la matriz y los granos de Co [7,21,126].…”
