Combustion joining of refractory materials
This paper overviews heterogeneous exothermic reactive systems as they apply to the joining of materials. Techniques that are investigated fall under two general schemes: so-called Volume Combustion Synthesis (VCS) and Self-Propagating High-Temperature Synthesis (SHS). Within the VCS scheme, applications that are considered include Reactive Joining (RJ), Reactive Resistance Welding (RRW), and S...
متن کاملCeramic/metal joining for structures and materials
The paper presents a discussion of the various types of ceramic joining within a conceptual framework based on the fundamentals of wetting, adhesion, and the thermodynamics of interfacial reactions. Examples are given of solid state diffusion bonding of Pt to alumina and brazing of AlN. Most ceramic-metal bonding is conducted at high temperatures, where chemical reaction is to be expected. The ...
متن کاملSTUDY OF JOINING MECHANISM (S) IN BRASS/STEEL/BRASS SANDWICH MATERIALS PREPARED BY SCRATCH BRUSHING METHOD
In this research, the mechanism of joining three sheets of metals, i.e. brass-steel-brass, by cold roll welding process has been studied. For this purpose, the two surfaces of steel sheets were roughened with stainless steel wire brush by different amounts, then the brass sheets were put on both sides of the steel sheets, before they were subjected to cold roll process. During rolling, peaks of...
متن کاملThe Importance of Materials Design in ESP and EST
University students in Iran need English to reinforce their specialist knowledge in order to meet their academic needs and not to be isolated from technological advances. The architecture students at the university level in Iran are no exception. Bearing this in mind, the present research intends to address itself to the following questions: 1) what are the problems in materials design in ESP...
متن کاملCombustion joining of refractory materials: Carbon–carbon composites
Refractory materials such as carbon possess properties that make joining them difficult. In this work, bonding of a carbon–carbon composite is achieved by employing self-sustained, oxygen-free, high-temperature combustion reactions. The effects of several parameters, such as the composition of the reaction media, and the values of the applied current and pressure, on the mechanical strength of ...
