Abstract
Molded green parts are fused together to form a bond or joint during the sintering process. The molded green parts are held in intimate contact with each other and sintered at temperatures sufficient to fuse the parts together. The process may entail dry fusing of part-to-part or it may include the use of a flux between the parts being fused together to enhance the bond.
Claims10
A method for co-sintering and permanently fusing together molded green parts formed from a powder injection molding composition to form a bond or joint therebetween comprising the steps of:
- a) molding at least two parts in a green state, wherein a nickel-based flux is disposed between said molded green parts in order to form a bond therebetween;
- and
- b) sintering the parts at an appropriate temperature while holding the parts in intimate contact to fuse the parts together.
