Research abstract

MOST ELECTROPOLISHING TREATMENTS FOR STAINLESS STEELS EMPLOY MULTIPLE OPEN MILDLY ACIDIC VESSELS. CONCERNS REGARDING FUMES AND CARRYOVER OF MORE AGGRESSIVE ACIDS MAKE COMMERCIAL TREATMENT FOR TITANIUM UNAVAILABLE. AN AUTOMATED ENCLOSED SINGLE TANK ELECTROPOLISHING MACHINE PROVIDES AN ENVIRONMENTALLY FRIENDLY METHOD FOR TITANIUM. WORKPIECES ARE PLACED IN A DRY VACUUM-TIGHT CHAMBER AND NECESSARY FLUIDS ARE SUCKED IN. ELECTROLYTES AND RINSE FLUID STORAGE CANISTERS ARE SEALED AND RINSE FLUIDS ARE CONTINUOUSLY DEACTIVATED. ALL SERVICING IS THROUGH REMOVAL AND REPLACEMENT OF SEALED TANKS. DETAILED LAYOUTS HAVE BEEN REVIEWED BY PROSPECTIVE USERS. A MAJOR MEDICAL IMPLANT MANUFACTURER AND THE TITANIUM DEVELOPMENT ASSOCIATION HAVE EXPRESSED THEIR SUPPORT AND OFFERED TECHNICAL ASSISTANCE. RESEARCH INCLUDES CONSTRUCTION OF A WORKING MODEL AND THE VERIFICATION OF PROCEDURES. IT ALSO INCLUDES METALLURGICAL CHARACTERIZATION OF ELECTROPOLISHED TITANIUM AND ZIRCONIUM SAMPLES.
