Abrasive wear performance of carbide composites

Wear mechanisms in abrasion and erosion of WC/Co and related hardmetals

“…In addition, the growth of cracks between one WC grain and the next breaks down the strong WC inter-grain network or skeleton in the material leading to a general weakening of the structure and increasing the likelihood of breakaway of WC grains. This process of build up of plastic strain in the WC grains, followed by fracture and breakup is consistent with the observation by Klaasen and Kubarsepp that XRD measurements confirmed that increased plastic strain was present in worn samples of WC/Co hardmetals [40].…”

Mapping of impact-abrasive wear performance of WC–Co cemented carbides

“…The properties of the conventional cemented carbides had been intensively studied [1][2][3][4][5][6][7][8][9][10][11][12]21,23,38,52,53] and are not provided here. The nomenclature of the hardmetal grades follows the designation of WC grain size (fine, medium, and coarse).…”

“…Wear rate graphs of cemented carbides are available and illustrate the general trends [9][10][11][12]21,23,41,52,53]. In paper [23] the most often used grades with 5-15 wt% Co content were omitted and the wear data were absent.…”

Performance of Ceramic-Metal Composites as Potential Tool Materials for Friction Stir Welding of Aluminium, Copper and Stainless Steel

“…Abrasion, adhesion as well as diffusion-controlled wear are the expected wear mechanisms. Previous research [26][27][28] has shown that at a similar volume fraction of carbides the TiC-based cermets, independent of their binder composition and structure in abrasive-erosion and in the abrasive wear conditions, are at a disadvantage in relation to the WC-based hardmetals. However, cermets with a steel binder are at an advantage over cermets with a NiMo-binder (at room temperature).…”
