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

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.
