Abstract
High-grade iron S27 alloy and cermet S27 + 50 vol % TiC are sprayed in Ar-N2 plasma with local protection from the air with a nozzle application. Under S27 alloy spraying, the oxygen content in the coating increases from 0.32 to 0.98%, the nitrogen content increases from 0.038 to 0.15%, and the carbon content is reduced from 4.26 to 3.47%. In the cermet coatings, the oxygen content increases from 0.56 to 1.96%, the nitrogen content increases from 0.068 to 0.64%, and the carbon content is reduced from 10.5 to 8.19%. Changes in the structure and microhardness of the materials investigated depend on the C, O, and N content and the rate of consolidation of sprayed particles.
