METHODS OF REFINISHING SURFACE FEATURES IN BULK METALLIC GLASS (BMG) ARTICLES BY WELDING

摘要

The present disclosure is directed to methods of refinishing surface features in bulk metallic glass articles by welding.

主权项

1. A method of refinishing a BMG article having a surface feature, the method comprising:
applying a BMG filler material to a surface feature wherein the BMG filler material comprises an alloy composition the same as the alloy composition of the BMG article; heating the BMG filler material and a portion of the BMG article adjacent the surface feature to a temperature above the melting temperature of the BMG filler material to melt the filler material and the portion of the BMG article adjacent the surface feature; and cooling the melted BMG filler material and melted portion of the BMG article adjacent the surface feature sufficiently fast to a temperature below the glass transition temperature of the metallic glass article without inducing substantial crystallization.
