ABSTRACT:
Undercarriage assembly components of track-type machines having a PTA welded wear-resistant coating and methods for forming such coated undercarriage assembly components are disclosed. Bodies of the undercarriage assembly components, formed of an iron-based alloy, have a material PTA welded on a surface or into an undercut or channel of the iron-based alloy. A heat treatment of the formed component further hardens the body. The portion of the outer surface of the undercarriage assembly components having the wear-resistant coating corresponds to a wear surface of the component during operation of the endless track of the track-type vehicle.
