Abstract
Abstract THE JOINING IN ELECTRICAL CONNECTION UNDER CORROSIVE CONDITIONS OF A PART MADE OF TITANIUM AND A PART MADE OF STEEL BY THE USE OF ENGAGING THREADS OR LUGS IS DIFFICULT. HOWEVER IF EACH PART IS FIRST COATED WITH A LAYER OF SOFTER BUT COMPATIBLE NON-OXIDIZING METAL, THEN THE TWO PARTS CAN BE JOINED TOGETHER IN A TIGHT ELECTRICAL/MECHANICAL JOINT. A TYPICAL SYSTEM IS A PLATINUM COATING FOR TITANIUM AND EITHER SILVER OR NICKEL UNDER COPPER FOR STEEL.
