Abstract: A method for bonding two glassy metal pieces, includes: (a) disposing the glassy metal pieces in an environment such that the surrounding of the glassy metal pieces is heated to a working temperature within a common supercooled liquid region of the glassy metal pieces; and (b) pressing one of the glassy metal pieces against the other of the glassy metal pieces under an elevated pressure while maintaining the working temperature for a suitable period of time so as to subject the glassy metal pieces to undergo solid state diffusion at an interface therebetween.

Abstract: A process for removing paint by high pressure waterjet blasting of painted surfaces wherein the waterjet comprises a ferrofluid or other liquid containing tiny magnetic particles suspended therein. The particles may be in colloidal suspension or be suspended by agitation and are preferably polymer coated. The liquid-magnetic particle mixture lends itself to electromagnetic process control, run-off maintenance and waste processing capabilities. Thereby, the process can employ process control and waste remediation options.
