Abstract
Injection molding has important advantages over other methods for the production of advanced ceramic parts with complex shapes. In this work, low-pressure injection molding was used to produce helical ceramic springs using two different kinds of molds. The ceramic powders used were submicrometer-sized alumina and partially stabilized zirconia. Sintered alumina and zirconia springs were obtained free of defects, with densities from 96% to 99% of the theoretical value. In preliminary mechanical tests, these ceramic springs supported axial deformations up to 10% before failure.
期刊介绍：
The International Journal of Applied Ceramic Technology publishes cutting edge applied research and development work focused on commercialization of engineered ceramics, products and processes. The publication also explores the barriers to commercialization, design and testing, environmental health issues, international standardization activities, databases, and cost models. Designed to get high quality information to end-users quickly, the peer process is led by an editorial board of experts from industry, government, and universities. Each issue focuses on a high-interest, high-impact topic plus includes a range of papers detailing applications of ceramics. Papers on all aspects of applied ceramics are welcome including those in the following areas:
Nanotechnology applications;
Ceramic Armor;
Ceramic and Technology for Energy Applications (e.g., Fuel Cells, Batteries, Solar, Thermoelectric, and HT Superconductors);
