Abstract

See full text

A process of forming an erosion, oxidation, and wear resistant shot chamber, either a gooseneck or a shot sleeve, is provided. The process utilizes a self-healing erosive wear resistant coating on a liner of refractory metal to serve as the working surfaces of a shot chamber. Such a shot chamber is expected to have an improved service life for die casting of corrosive metals and alloys, including hot chamber die casting of aluminum alloys. An improved hot dipping process using stirring in the molten metal bath is also disclosed.
