Benefits of technology
This patent is about making parts that are resistant to wear and impact. These parts are made by combining a metal with a ceramic material. This combination makes the part stronger and longer-lasting, and it can withstand more damage than either material alone. This can be useful for making any part that gets a lot of use or needs to be protected from impacts. The ceramic material can be distributed throughout the part evenly or unevenly, depending on what's needed.
Problems solved by technology
While in some examples, ceramic material may be distributed uniformly throughout a component, in other examples, ceramic material may be distributed non-uniformly throughout all or part of a composite component.

Overview
[0028]As noted above, manufacturing of composite components is often difficult due to the varying material properties of the materials from which the composite component is made. This application describes composite components comprising ceramics and metal or metal alloy(s) that, together, exhibit improved resistance to wear, friction, and / or impact compared with components formed of ceramic or metal alone. This application also describes various techniques for manufacturing such composite components. By way of example and not limitation, the composite components described herein may be used in the fields of excavation, manufacturing, metallurgy, milling, material handling, transportation, construction, military applications, and the like.
[0029]In general, composite components as described in this application include a base metal and one or more ceramic materials. This application describes techniques for casting such composite components in sand and / or investment casting mo...

Abstract
Methods and processes are described that form ceramic wear surfaces on the outer surface of a cast part. A mold having a mold cavity is provided. The mold cavity may be washed using a refractory wash to provide for a smoother finish to the surface of the cast part and to maintain mold integrity. An adhesive is applied to predetermined locations in which increased wear during the use of the cast parts is anticipated to occur. Ceramic material may be applied to the predetermined locations by various means. A mask may be used to remove excess material from areas other than the predetermined locations. A molten metal is poured into the mold cavity and allowed to cool to form a cast part with a ceramic wear surface.
Description
[0001]This application is a continuation of and claims priority to U.S. patent application Ser. No. 13 / 070,418, filed on Mar. 23, 2011, the disclosure of which is incorporated by reference herein.BACKGROUND[0002]Wear or impact resistant components are desirable in a variety of industrial, commercial, and military applications. For example, mining, construction, heavy equipment, automotive, military, and other applications rely on components that are resistant to wear and impact.[0003]Recently, composite components formed of two materials having different material properties have been used. For example, a composite component may be made by combining a first material having a high hardness with a second material having a high toughness, to produce a composite component having characteristics of both materials (i.e., high hardness and toughness).[0004]However, manufacturing composite components is often challenging due to the different properties of materials used to form the composite...
