Alternative technology to manufacture bimetallic products by using self-propagating high temperature synthesis

Abstract

Abstract. Electric welding is usually used for surfacing metal products. This process may be laborious and timeconsuming, which at the same time excludes welding jointing throughout the product surface. The productivity of powder tape surfacing is pretty low, up to 2.7 kg / h, with a melting rate of 13-15 min / h. The use of the selfpropagating high-temperature synthesis for producing a liquid thermite alloy aimed at further surfacing throughout the metal surface of a detail can provide a cost-effective and viable alternative technology for manufacturing bimetallic products.

Study on the Microstructure of Anti-Corrosion and Wear Resistant Coating on the Inner Wall of Equipment Pipeline and the Synthesis Mechanism of Ceramic Coating

“…In recent years, self-propagating high temperature synthesis [5][6][7] (SHS), a new surface coating technology, has become a promising material surface modification technology. Therefore, in order to solve the problem of poor bonding between the coating and copper substrate, the Al-Fe2O3 /Al NiO binary aluminothermic reaction system was used to produce ceramic composite coating on the inner wall of copper tube by centrifugal self-propagating high temperature synthesis technology.…”
