aisi 431 nitrated

1. Introduction - Hindawi

Concerning that both AISI 304 and 316 were nitrated in same conditions, more high hardness values in AISI 304 samples depth are observed. Besides, higher values were obtained in samples with plasma nitriding processes, probably due to the applied process temperature (plasma, T = 430°C; gaseous and liquid, T = 570°C).

Wear performance of DLC coating on plasma nitrided

Mar 01, 2019 · The hardness, microstructure, and adhesion of coatings are also studied. In this research, the wear behavior of various substrates of Astaloy Mo with different densities and cooling rates is investigated. Before the tests, these substrates were plasma nitrated and then a DLC coating was deposited on the nitrided layer. 2.

  • AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsAcknowledgmentsThe nitriding behavior of austenitic stainless steels (AISI 304 and 316) was studied by different cold work degree (0% (after heat treated), 10%, 20%, 30%, and 40%) before nitride processing. The microstructure, layer thickness, hardness, and chemical microcomposition were evaluated employing optical microscopy, Vickers hardness, and scanning electron microscopy techniques (WDS microanalysis). The initial cold work (previous plastic deformations) in both AISI 304 and 306 austenitic 420 Martensitic Stainless Steel Bar Interlloy 420 has a corrosion resistance similar to 410 grade, better than 416 grade, but lower than 431 grade, also lower than most of the 400 series ferritic stainless steels and all
