Rather than coating a high-melting-point refractory metal onto copper, they have made a Refractory Metal Coated Copper foil, applied as a clad layer through plasma transferred arc melting
. This method clads virtually any metal to another metal independent of their diversity in properties, and provides corrosion and wear resistance, hardness and coefficient of friction for a variety of aerospace, defense and transportation applications.
Since the arc melting
process is a dynamic stochastic process, it is difficult to make a precise deterministic model for an arc furnace load.

Furnace Scrap Volatile Organic Chemicals Preheater (VOC)--98% reduction by weight or <20 ppmv as propane at outlet.
Army ARDEC RDAR-MEE, Materials Manufacturing and Prototype Technology Division, Picatinny Arsenal, N.J., American Engineering & Manufacturing, Amherst, Ohio, and Advanced Design Industries Inc., Sheffield Village, Ohio, are made with a plasma arc melting
furnace technology that has been adapted to a continuous process.
A source of advanced industrial arc melting
of molybdenum includes the individual experiments carried out in 1943 to explain the possibilities of arc vacuum melting of molybdenum using alternating current (4) which laid foundations to the development of the process of production of molybdenum in the form of larger blanks than those produced at that time by powder metallurgy processes thus expanding the area of application of molybdenum as the structural material.
The continuous arc melting
concept is driven by the central cathode (graphite electrode) inside the inner vessel and the corresponding conductive bottom anode.
The advantages of electron beam remelting of molybdenum were utilised in comparison with vacuum arc remelting, the possibility of remelting the metal in any form (briquettes, powder, shavings), whereas in arc melting
it is necessary to prepare a consumable electrode .
It utilizes nobake molding and arc melting
, and performs heat-treating and patternmaking in-house.
Recalls Consultant Roy Lobenhofer, who worked at Clow and several other iron foundries in melt control and metallurgy: "During those days, ACIPCO installed a large cupola, Caterpillar's Mapleton Foundry put in a large induction shop and John Deere's East Moline foundry went to electric arc melting
, so you can see that there was a clear choice of what was best."
