Excavator bucket tooth wear analysis

Excavators used in mining industry have bucket teeth usually made up of hard alloys. In order to improve the anti-wear properties of these alloys coatings are provided. The purpose of the present work is to make the deformation analysis of the bucket teeth. It was observed that maximum stress occurred at the fixed joint of teeth and tongue, while the maximum wear takes place at the tip of tooth. The abrasive nature of soil is one of the reason of tip wear.
