Use of pulsed spray airflow for electric arc spraying of different types of wires

The object of research is the control process formation a spraying air flow and transfer particles liquid metal from electrodes during arc spraying. One problem areas oxidation sprayed by oxygen their transportation to surface. This leads sufficiently large amount oxides chemical elements, which significantly deteriorate adhesion strength burn out alloying elements that are necessary obtain wear-resistant corrosion-resistant coating. suitability durability coatings use depends on substrate. In course study, methods were used determine coating base – Steffens method for studying microstructure taken as basis. data was processed dependencies plotted. proposed makes it possible improve quality resulting in terms such an indicator improvements composition. And also influence composition controlling molten using pulsating flow. obtained results approbation allow us consider effective, evidenced coatings. due fact correctness formulation solution provided adequate results. contrast existing methods, one harmful involved coating, layer with required performance characteristics. allows its without significant capital costs. addition, issues resource energy saving being addressed, since burnout decreases consumption metallization decreases. To solve this problem, simple design pulsator proposed, provides ability spray adjusting level overlapping holes.
