Abstract

The authors address to the issue of mainstream directions and application fields of nanostructured coated electrodes and flux cored wires, their distinctive advantages and shortcomings. Some consideration is given to use of refractory nanoparticles and their influence on the structure and properties of metal when welding and surfacing with flux cored wires and coated electrodes. The results of research carried out in this sphere are analyzed.

Highlights

  • The beginning of the 21st century is distinguished by the rapid development of nanotechnologies and nano-materials, which are used in the most important fields of human activity and in all advanced economies of the world

  • The importance of nanotechnologies and nano-materials is highlighted by such contributions to this field as a great number of scientific papers, whose authors deal with the specifics of nano-materials, the intensity of adopting fundamental and applied engineering products, and the growing amount of investments

  • The number of scientific papers focused on nano-materials and nano-technologies is quite impressive, since approximately 15-25.000 articles, whose authors address to this range of problems, have been published over the last few years; it is definitely a very significant factor [1]

Summary

Introduction

The beginning of the 21st century is distinguished by the rapid development of nanotechnologies and nano-materials, which are used in the most important fields of human activity and in all advanced economies of the world. The importance of nanotechnologies and nano-materials is highlighted by such contributions to this field as a great number of scientific papers, whose authors deal with the specifics of nano-materials, the intensity of adopting fundamental and applied engineering products, and the growing amount of investments. These activities will be amongst the basic factors of defense, scientific and economic development of the countries in the decades [1].
