“…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 contributions of these research groups promoted a consolidation of an ASTM standard for a gouging abrasion test using jaw crushers, edited for first time in 1997 and reapproved in 2002, 2007 and finally in 2013. More recently, a research group from Chalmers University (Lindqvist and Evertsson, 2003) studied the wear of jaw crushers, but their goal was to transfer a developed wear model for cone crushers.…”

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.

“…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]. One of the most common approach is the usage of a friction wheel test (FWT), known from the normalized standard tests after [16] with wet slurry and steel wheel and [17] with dry sand and rubber wheel.…”

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.

“…These standards state that the results must not be extrapolated to service conditions and only they are valid for comparative purposes [22,23]. The test selection is one of the major problems for the analysis of wear behavior, it is questionable the correlation between different procedures [24,25]. Therefore, it is interesting to use different wear tests using conditions test as similar as possible.…”

Mixtures of AISI M2 high speed steel and vanadium carbide (3, 6 or 10 wt.%) were prepared by powder metallurgy and sintered by concentrated solar energy (CSE). Two different powerful solar furnaces were employed to sinter the parts and the results were compared with those obtained by conventional powder metallurgy using a tubular electric furnace. CSE allowed significant reduction of processing times and high heating rates. The wear resistance of compacts was studied by using rotating pin-on-disk and linearly reciprocating ball-on-flat methods. Wear mechanisms were investigated by means of scanning electron microscopy (SEM) observations and chemical inspections of the microstructures of the samples. Better wear properties than those obtained by conventional powder metallurgy were achieved. The refinement of the microstructure and the formation of carbonitrides were the reasons for this.
