Reinforcement of metal-ceramic coatings in the course of their partial fusion

Reinforcement of metal-ceramic coatings in the course of their partial fusion Factors and mechanisms responsible for the appearance of layered structures of variable cross section in protective coatings based on self-fluxing alloys were studied. A number of structural fragments of composite coatings based on safe-fluxing PG-10K-01 and PG-SR3 alloys (initial formulations and those reinforced with oxide ceramic particles), formed by sputtering in a plasma flux and then partially fused in a furnace, by a gas-oxygen flame, and with laser and electron beams, were revealed and studied. The relationships of the element distribution across the coating layer as a whole and in separate phases were determined. The effect exerted on the chemical composition and microhardness of coatings by the size, structure, and arrangement of inclusions in the coating cross section was demonstrated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Factors and mechanisms responsible for the appearance of layered structures of variable cross section in protective coatings based on self-fluxing alloys were studied. A number of structural fragments of composite coatings based on safe-fluxing PG-10K-01 and PG-SR3 alloys (initial formulations and those reinforced with oxide ceramic particles), formed by sputtering in a plasma flux and then partially fused in a furnace, by a gas-oxygen flame, and with laser and electron beams, were revealed and studied. The relationships of the element distribution across the coating layer as a whole and in separate phases were determined. The effect exerted on the chemical composition and microhardness of coatings by the size, structure, and arrangement of inclusions in the coating cross section was demonstrated.
