Recent applications of microwaves in materials joining and surface coatings

The conventional methods of manufacturing and materials processing are getting obsolete owing to the higher energy consumptions, large processing times and poor characteristics of processed components. The limitations of conventional processing techniques for processing of large varieties of advanced materials which includes metal matrix composites, ceramics, cermets, metallic alloys, functionally graded materials and fiber-reinforced plastics forced researchers to find alternative and novel methods of manufacturing and material processing, which can overcome the limitations of conventional methods. Hence, it is mandatory to develop a new concept for processing advanced materials, which can provide better mechanical properties, reduced defects and economic advantages in terms of power and time savings. Microwave material processing emerged as one of the novel methods of material processing which can satisfy the present requirements and can yield a better product at reduced costs and processing time. This article discusses some of the novel recent applications of microwaves in the area of manufacturing.
