Abstract :
An excavator (dredging machine) is a
hydraulic type heavy machinery operated by humans to
dredge which is generally used continuously in large
scale mining operations. However, in the process, the
gear dredges on the engine will experience severe
erosion. The aim of this work is to improve the service
life of the excavator's dredging gear to reduce the free
time needed to periodically return the dredging gear in
excavation. This objective is carried out by coating the
dredge gear excavator (with high-tension steel) with
four wear-resistant alloys with manual arc welding.
Comparative wear is tested on regular teeth and coated
excavators are carried out in the field and laboratory
(ASTM G-99),
