Restoration of surfaces of metal products by plasma spraying of powder materials

The results of improvement of the technology of machine parts restoration by applying composite coatings are considered. A new powder composition for plasma spraying is created, which includes hard chromium-nickel alloys, ironbased alloys and aluminum powder. Measurements of hardness, wear resistance and impact strength have confirmed the high quality and reliability of the coatings, the developed composition surpasses existing analogues. Certain technological modes are suitable for restoring worn surfaces of agricultural machinery parts.
