In the oil sands industry a single ultra-class shovel tip can lose more than 35kg of steel mass in one operating day. Equipment downtime is significantly increased with frequent stoppages to replace worn shovel teeth. This leads to a substantial loss in shovel availability and utilization, as well as a considerable increase in consumable cost.This paper develops a means to predict the wear performance...
The technological evolution of more efficient natural gas-fuelled large bore engines aggravates the load situation within the engine and thus as well the tribological system valve spindle/seat ring. As a result of these changes, valve recession increases and component lifetime decreases, i.e. higher failure rates and more frequent service intervals. The tribological issues can be traced back to the...
Wear is a multi-faceted phenomenon that occurs through a number of mechanisms. Surface mining operations are principally impacted by abrasive wear during the excavation process. Equipment downtime due to ground engaging tool (GET) abrasive wear significantly affects production of a mining operation. In comparison to the ASTM G65 constant load abrasion test, an equally simple cyclic load test has been...
