Wear Behavior of Hardfacings Excavator Bucket Teeth Wear Resistance Enhancement Via Hardfacing

New developments in the field of continuously operating earth moving equipment demand a new way of improving wear resistances of these equipment parts which directly involved with different types of sand and rocks during their operation in harsh field environment. Wear caused by the impact and abrasion action of hard particles is a major problem in many industrial applications and particularly in the area of earth moving machinery. This book, therefore, provides the solution to enhance the useful life of the excavator bucket teeth in order to decrease the idle time required to reinstate the teeth periodically during working. The objective was carried out by means of hardfacings, where the effect of the hardfacings on the extent of wear and the wear characteristics of the excavator bucket teeth were examined. The wear rates of hardfaced teeth were significantly lower than those of un-hardfaced teeth, indicating the great improvement in wear resistance provided by the hardfacings.
