Fabrication of laminated mold with brazing of alloy steel by Nickel-based brazing filler metal foil made by rapidly solidification technology

摘要

Nickel-based brazing filler metals are primarily used where extreme heat and corrosion resistance is required. They are commonly used in the manufacture of jet and rocket engines, chemical processing equipment, and nuclear reactor components. Many commercial and cryogenic applications are now in service. These brazing filler metals are normally supplied as powders. Recently, flexible nickel-based amorphous brazing foil has been prepared by a rapid solidification technology. Previously there materials were mainly available only in powder or paste forms. The greatest advantage of this rapidly solidified nickel-based amorphous brazing foil is its flexibility. This flexibility allows the foil to be used on curved joints. The foil also proved to be a more effective method of applying the brazing filler metal in joints having a large area. On the other hand, the mold with complex and conformal cooling channel for plastic injection molding is very important parts for manufacturing field. So in this study, brazed joint laminated mold with complex and conformal cooling channel for plastic injection molding is fabricated by brazing technology with flexible nickel-based amorphous brazing foil made by rapid solidification technology.
