Abstract
A tough, wear resistant body is provided. The body includes hard carbide particles embedded in and bonded with a first casted ferrous matrix material such as steel or cast iron. The body may be embedded in and bonded with a second steel matrix to form a wear resistant composite. The second steel matrix has a melting point at least 200 degrees F. greater than the melting point of the first ferrous matrix, thereby facilitating a metallurgical bond between the surface of the wear resistant body and the second steel matrix. The composite structure is particularly suitable for earthmoving and other severe mechanical applications.
