Abstract
Official abstract text for this publication.
A powder feed for injection molding process includes a first metal powder, and a second metal powder. The first metal powder and the second metal powder are mixed together evenly. The second metal powder has a mass percentage of about less than 10% of a total mass of the powder feed for injection molding process. The first metal powder is resistant to the corrosion by a chemical reagent, and the second metal powder is corrodible in the chemical reagent.
First claim
Opening claim text (preview).
What is claimed is: 1 . A powder feed for injection molding process, comprising: a first metal powder, and a second metal powder, wherein the first metal powder and the second metal powder are mixed together evenly; the second metal powder has a mass percentage of about less than 10% of a total mass of the powder feed for injection molding process; the first metal powder is resistant to the corrosion by a chemical reagent, and the second metal powder is corrodible in the chemical reagent. 2 . The powder feed for injection molding process of claim 1 , wherein the first metal powder is stainless steel metal powder. 3 . The powder feed for injection molding process of claim 2 , wherein the stainless steel metal powder is at least one of 17-4 PH, 316L and SKD61. 4 . The powder feed for injection molding process of claim 1 , wherein particles of the first metal powder are micron-sized. 5 . The powder feed for injection molding process of claim 1 , wherein the second metal powder is at least one of a carbon-based iron powder and a low carbon steel-based alloy powder. 6 . The powder feed for injection molding process of claim 5 , wherein the second metal powder is G1010, a carbon-based iron powder. 7 . The powder feed for injection molding process of claim 1 , wherein particles of the second metal powder are micron-sized. 8 . The powder feed for injection molding process of claim 1 , wherein the injection molding feed further comprises a binder, the first metal powder, the second metal powder, and the binder are mixed together evenly 9 . The powder feed for injection molding process of claim 8 , wherein the binder has a mass percentage of about less than 10% of the total mass of the powder feed for injection molding process.
