Abstract
A method for forming ceramic articles for prototypes that involves the use of metal particles or metal-coated ceramic particles that are formed into ceramic articles using a laser engineered net shaping process. The metal particles or metal coating on the ceramic particles facilitates bonding between the ceramic particles to enable quick manufacture of ceramic articles using the laser engineered net shaping process. The ceramic articles may be ceramic core prototypes and may be used in a variety of different industries.
Claims9
A method for forming a ceramic article comprising the steps of:
- providing a powder comprising a ceramic powder and at least one metallic material forming a coating on the ceramic powder;
- applying a laser energy source to the powder to melt the at least one metallic material forming the coating to bond the powder and form the ceramic article;
- removing at least a portion of the at least one metallic material forming the coating;
- and
- sintering the ceramic article.
