Abstract
Plasma transferred arc welding (PTA) is used to produce coating for wear resistance application in earth moving equipment. The coating is designed to have balanced toughness and hardness, optimal microstructure to perform in the wear modes the components are subject to. 4~ 6 times improvement in wear life compared with hardened steel was achieved as demonstrated in dry sand/rubber wheel test and Caterpillar proprietary abrasion wear test
