摘要：
Ceramic orthopedic implants may have one or more dense inner layers and one or more porous outer layers. Methods for manufacturing the implants may include one or more stages during which the dense inner layer(s) are partially compressed. At least one porous outer layer may include coating particles that are present at a surface of one or more inner layer(s) while pressure is applied to attach the coating particles to the inner layer(s) and to further compress one or more of the inner layer(s). Various layers may be formed until an implant, or other device, is formed having the desired density gradient and/or other properties, as disclosed herein.
