Abrasive Wear of Digger Tooth Steel - CORE
The influence of silicon carbide SiC abrasive particles of 20, 30, 40, 50 and60μm size on carburized digger tooth steel was studied. Four types of steel, withdifferent hardness, were tested at two constant linear sliding speeds and undervarious loads of 10, 20, 30, 40 and 50N. Tests were carried out for sliding time of0.5, 1.0, 1.5, 2.0 and 2 ......
Materials selection to excavator teeth in mining industry ...
Tooth wear is tracked over a 6-day period and wear rate statistics are computed for 6 teeth. This validates the system and provides an example of how wear patterns can be recorded and analysed by ...
Abrasion, Wear Life, Costs Factor in the Hard Facing ...
What do buckets, teeth, moldboards, dozer blades, shears, and even grousers all have in common? Contact with the ground is only partially correct. They all contact the ground with possible abrasion, and it’s the level of abrasion, the desired wear life, and the cost of new ground-engaging tools that determine whether hard facing is a maintenance option. Hard facing is the application, by ......
Abrasive wear of alloys for ground engaging tools - CORE
Abrasive wear of alloys for ground engaging tools . ... The work highlights wear mechanisms of excavator digger teeth and its laboratory recreation using tumbler and scratch tests. Martensitic steels found to be better for coal mining whereas bainite showed higher wear resistance for iron ore mining as it involves impact.<br /...
Abrasion-induced microstructural changes during low stress ...
Wear, 151 (1991) 1-12 1 Abrasion-induced microstructural changes during low stress abrasion of a plain carbon (0.5% C) steel B. K. Prasad and S. V. Prasad* Regional Research Laboratory, CSIR, Bhopal 462 026 (MP) (India) (Received April 9, 1990; revised and accepted June 5, 1991) Abstract A plain carbon (0.5% C) steel was subjected to various heat treatment cycles to produce a variety of ......
How to choose the right excavator teeth - eiengineering ...
Wear life of excavator teeth are impacted differently by various materials. Sand is extremely abrasive, rock, dirt and other materials being excavated or loaded will impact on its wear life depending on their quartz content. The greater the wear surface, the longer the teeth will last before replacement.
Carbidic Austempered Ductile Iron (CADI™) - Applied Process
CADI™ is utilized where abrasion (wear) resistance is of primary concern. It is more wear resistant than Grade 1600 (GR 5) ADI, less expensive and tougher than many abrasion resistant irons and can replace Mn steel at an equal or lower cost. Typical applications of CADI™ include: Rasp Bars; Wear Plates; Plow Points; Digger Teeth; Tip Holders...

US3912338A - Wear resistant grouser bar - Google Patents
A steel bar for welding to an endless track to impart wear resistance to the track while, also, improving the grip of the endless track on the ground in which the bar is constructed to extend transversely to the endless track and is formed at the base for being welded to the track while the outer edge is provided with hardfacing in the form, especially, of cemented hard carbide inserts which ...
 Ball Cratering or Micro-Abrasion Wear Testing of Coatings
Abrasive wear occurs when material is removed from the surface of a component by a ... such as the wear of digger teeth when working in gravel. It can also occur with two smooth ... gouges. If the component is made from a ductile material, such as steel, the wear debris can be spiral in shape, similar to machining swarf. For very hard materials ......
