| Abstract: |
A significant group of steel-making process parts is exposed to high contact pressure, shock abrasive wear and elevated temperature. Besides, high productivity of repair is necessary because of part's large sizes.
Analysis of coating metallographic investigations, wear and corrosion test results, full-scale tests shows that successful restoration of base share of these parts is possible by High Velocity Air Fuel Process (HVAF). It excels alternatives (HVOF, Detonation Spraying, Plasma Spraying, Cold Spraying) at productivity noticeably. At the same time production costs are 2-2.5 times less.
Examples of typical steel-making process parts which were HVAF restored at Joint Stock Company
