A carbide insert having fracture orienting grooves and a method for forming a cutting element for an earthworking machine. The carbide insert is placed in a groove formed on the cutting edge of the cutting element and there maintained by deforming walls of the cutting element into intimate contact with the carbide insert.

Earthworking machine cutting element having carbide insert and method

A method for forming a blade adapted to be attached to an earthworking vehicle and the resultant wear resistant blade has a wear surface assembly which includes a carbide insert sandwiched between a steel plate and a composite material within a pocket on the front surface of the blade spaced from the blade cutting edge.

Method for forming wear surfaces and the resulting part

A method for forming a wear surface on a metal substrate has a slurry which includes wear resistant particles, powdered steel, and binder system positioned on the metal substrate by retaining walls for a time sufficient for drying the slurry and forming a composite material of preselected thickness 'T'. The retaining walls are then removed and the substrate and the composite material are heated and passed through a rolling mill compressing the composite material.
