One of the essential goals of this work 1s to develop component designs (Including attachments) and manufacturing processes in ceramics that cost no more than the parts they replace. After several years' effort

— and many design, test, manufacture, and cost analysis iterations -- this goal still appears attainable. For example, 1t has been estimated that the cost of the crosshead wear pad at Cummins usage levels will be about one-third greater Including attachment than the current metal-based processes. However, 1f others have requirements for components of approximately this size, higher volumes could ultimately cut this cost in half

— in which case the crosshead with ceramic pad could be produced at lower cost than the original.
