An empirical ranking of a wide range of WC-Co grades in terms of their abrasion resistance measured by the ASTM standard B 611-85 test

Dry Reciprocating Sliding Friction and Wear Response of WC–Ni Cemented Carbides

“…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].…”

“…Furthermore, hardness, toughness and strength characteristics can be tuned by adding an adequate amount of metal binder during the liquid-phase sintering process, as mentioned by e.g. [18][19][20][21][22][23]. The superior properties obtained with cobalt bound materials have made this metal the most commonly used binder.…”

Wear of Hardmetals

“…Depending on the conditions, abrasion of hardmetals normally shows a strong dependence on the hardness of the hardmetal (Gant & Gee, 2001;Herr et al, 2001, Luyckx, Sacks, & Love, 2007Quigley, Luyckz, & James, 1997). For abrasion under high stress conditions such as those experienced in the ASTM B611 test, the behavior follows an approximately log linear relationship at hardness values above about 1200 HV that can be expressed as:…”

Focused ion beam tomography of WC-Co cemented carbides

“…Refs. [4][5][6][7][8][9][10][11][12][13]). Accordingly, a reliable and precise quantitative metallographic description of hardmetals has then become a mandatory requirement.…”
