Producing Bimetals by Direct Melting of the Bronze Machining Chips into Steel Supports

Abstract

The bimetals can satisfy some requests of the working conditions impossible to be obtained using one single metallic material. The bimetallic pieces are obtained by the different production methods by covering of a steel support with the nonferrous alloys layers. The possibility of bimetals producing by direct melting of the bronze machining chips into steel support is considered in this work. In this way the superior valorisation of the metallic scraps for obtaining bimetallic steel-ronze parts was studied. The recycling of the metallic wastes as final products with added value is possible to be achieved. In this paper the flow sheet for the bimetal manufacturing through this method was showed. Also the parameters that influenced the quality of bimetal were analysed. The quality of the bimetal was analysed in term of contact zone quality. The interface zone of two alloys was investigated through the methods of metallographic and microscopic analyses.
