Description:

A new method of applying thin, electrically conductive films to a substrate as a replacement for continuous strip electroplating (CSEP) is desirable from an environmental standpoint as a means of limiting chemical and metallic contamination of wastewater and the economic costs of treatment.

AVCA Corporation has done preliminary design work on a method and apparatus for generating thin films by levita- tion of electrically conductive materials in an electromag- netic containment device and transfers them to a ferrous substrate passing under the device on a continuous basis as a replacement for CSEP.

A question that must be answered before further develop- ment of the levitation portion of the design takes place is the quality of the bond achieved by the direct application of a liquid metal to a relatively cold ferrous substrate. Prelimi- nary research indicates that such bonds are worthwhile

AVCA Corporation has designed a supplemental process of enhancing these, bonds that can be dovetailed into the levitation portion of its design that involves reliquefaction of the film while subjecting the substrate to a strong magnetostrictive effect.

This research proposal involves the construction of a bench top device for testing the magnetostrictive interaction and - for modelling the entire process for the purpose of deter- mining instrumentation requirements.
