Study on Preparation, SLS and Post-Process of ZrO Coated Powder

A novel method named dissolution-precipitation process was used to prepare zirconia (ZrO2) ceramic composite powder. Nylon 12 was used as a binder to be coated on the surface of ZrO2 powder. The coated powder obtained by dissolution-precipitation process is more uniform and suitable for selective la...
