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.
