The structural-phase composition and some properties of medium-carbon steel modified surface after cathodic plasma electrolytic nitriding in a solution of ammonium chloride and ammonia have been studied. It is shown that cathodic nitriding of a steel surface is accompanied by high-temperature oxidation with the formation of oxides FeO, Fe2O3, and Fe3O4, as well as nitrogen diffusion and quenching with the formation of FeN, Fe3N, and Fe4N phases, martensite and the retained austenite. The competing effect of surface erosion by the actions of discharges and high-temperature oxidation on the morphology and roughness of the surface was revealed. It was established that the maximum microhardness of the modified layer reaches 1040 HV, and the corrosion current density of the nitrided surface decreases by a factor of 1.5–2.4.

Quenching And Tempering

One of ways to improve properties of materials without changing the product shape toobtain the desired engineering applications is heating and cooling under effect of controlledsequence of heat treatment. The main aim of this study was to investigate the effect ofheating and cooling on the surface roughness, microstructure and some selected propertiessuch as the hardness and impact strength of Medium Carbon Steel which treated at differenttypes of heat treatment processes. Heat treatment achieved in this work was respectively,heating, quenching and tempering. The specimens were heated to 850°C and left for 45minutes inside the furnace as a holding time at that temperature, then quenching process wasperformed in four types of quenching media (still air, cold water (2°C), oil and polymersolution), respectively. Thereafter, the samples were tempered at 200°C, 400°C, and 600°Cwith one hour as a soaking time for each temperature, then were all cooled by still air. Whenthe heat treatment process was completed, the surface roughness, hardness, impact strengthand microstructure tests were performed. The results showed a change and clearimprovement of surface roughness, mechanical properties and microstructure afterquenching was achieved, as well as the change that took place due to the increasingtoughness and ductility by reducing of brittleness of samples.
