Increasing of operational properties, especially wear-resistant surface of industrial components may be achieved by modifying the surface layers of nano forms through the providing of nanopowders into the molten pool at electric-arc surfacing and coating during thermal spraying.
Entering within the local areas of the surface portions considerable additional energy allows the creation of conditions for phase and structural changes in the material and in the case of special operating environments - and modify the chemical composition of the surface layer of the material . The additional energy is accomplished using a pulsed arc that is formed between one of the electrodes of the main flow of the plasma generator and the surface of the product.
The base energetic characteristics of plasmatrons on complicated gases mixtures are researched; experimental researches of the role of electromagnetic fields on the formation gas-powders streams in the processes of plasma spraying are fixed; working models of equipment are developed; influence of regime parameters on the results of the quantity of plasma coatings from the materials different physical nature is studied; the main peculiarities of coatings are pointed out; technological recommendations on application of magnetic controlling of formation plasma coatings are proposed
