“…Hardness of matrix in the high energy CIAT showed negative effect on the wear resistance of materials. Increasing matrix hardness of dual phase composite increased the CIAT wear rate that is in opposite with the experimental results in the pure abrasion environment [23][24][25], because the wear mechanisms in the high abrasive energy impact-abrasion conditions is the suffer damage to the carbides phase as a result of fracture of the carbides through the high impact stress [5,6]. The cracked carbides are then more susceptible to removal by the subsequent abrasion action.…”

Carbide-matrix hardfacings reinforced with spherical and angular particles of different size and density have been investigated about correlation of their specific material parameters-especially matrix hardness and microstructure parameters-with the wear rates in continuous impact abrasion test (CIAT). For this study, 12 different hardfacings have been characterized by the quantitative metallographic method for determination of specific structural parameters, such as the mean carbide diameter, carbide area fraction, and a distribution parameter of inter-particle distances (L IPD ). Results showed the high influence of the matrix hardness on the CIAT wear resistance followed by effect of the mean particle size. The length of inter-particle distance (L IPD ) has exhibited stronger additional effect on CIAT wear rate than carbide area fraction, whereas particle form (spherical or angular) showed no significant differences.

“…Basically, most of wear data was produced by two research groups: the US Bureau of Mines (closed in March 1996) in EUA (Blickensderfer et al, 1985;Tylczak et al, 1999;Hawk et al, 1999), and Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia (Sare et al, 1980;Sare and Arnold, 1989;Sare and Constantine, 1991;Sare and Arnold, 1995;Sare and Constantine, 1997).…”

The use of a gouging abrasion test to evaluate the wear of jaw crushers is revised in terms of its procedures, considering the effects of the most significant variables, such as the minimum amount of crushed material and the minimum opening between the jaws during the crushing cycle (minimum discharge aperture). A correlation between the work hardening of jaws and the amount of crushed material is presented. The wear of stationary and movable jaws is compared, being the results dependent on the jaw's material and the discharge aperture. The abrasiveness of several rocks was evaluated, showing a good correlation with their Mohs hardness.

“…The definition of a proper abrasive wear test process is a difficult task, because of the utilized hard and sharp abrasives; the test equipment is also strongly exposed to wear. Testing and comparing different hardfacing layers in the field is a long lasting process [13]. To reduce field trials and to obtain meaningful results on the wear resistance of such hard layers, several methods have been established in the last decades [14,15].…”

The aim of this study is to investigate the abrasive wear loss as well as the wear mechanisms of hardfacing layers with and without tungsten carbides (WC) included in the matrix in different friction wheel test (FWT) configurations. The FWT setup is varied in regard to the materials of the rotating wheels, whereat steel and rubber materials are utilized to achieve varying wear mechanisms as representative conditions for stone milling as well as low density wood cutting processes. Coatings including fine particles of WC highlight the highest resistance against abrasive wear in rubber wheel testing condition, at which microcutting acts as the dominant effect. In comparison to the hardfacings without WC, the mean material loss majorly decreases by about 75%. On the contrary, the mean material loss of fine WC reinforced coatings increases up to 93% compared to the condition without WC if a steel wheel is utilized as rotating counterpart. Thereby, the coatings with comparably coarse WC reveal the minimum material loss with a decrease over 70% compared to the condition without WC. In conclusion, the inclusion of WC in hardfacing coatings significantly increases the wear resistance. The experimental wear test results highlight the fact that in order to achieve the optimal wear resistance the material characteristics of the hardfacings need to be properly defined considering the predominant wear mechanisms under inservice conditions.
