On the machinability of ceramic compacts

摘要

Conventional machining of compacted ceramic per- forms can be a cost-effective method of making small production runs of complex-shaped engineering cera- mics. This paper discusses the factors influencing chip- ping resistance and edge retention for two spray-dried zirconia powders. The chipping resistance did not deteriorate significantly, neither did the swarf size change after pre-sintering the components at tempera- tures up to 1000 deg.C despite a twenty-fold increase in compact strength.
