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),
