Response of AISI 420 stainless steel to plasma nitriding at anodic (ground) potential was studied. • Edge effect did not appear on the nitrided sample. • Microstructure and properties of nitrided layer were comparable with conventional or active screen plasma nitriding.
The deep-rolling, mechanical surface treatment was modified by applying heat during operation on the martensitic stainless steel AISI 420. Fatigue performance of the high-temperature deep-rolled condition was investigated and compared with the non-surface-treated and room-temperature deep-rolled conditions. Thermal and mechanical …
Electrochemical corrosion behavior of untreated and carburized AISI 420 steel samples were studied using potentiodynamic polarization technique. Cyclic potentiodynamic polarization curves were recorded according to the ASTM G61 [50] standard, which is recommended for evaluating the pitting corrosion tendency of materials …
Short time intervals of cooling can lead to heat accumulation resulting in discoloration of AISI 420 (X20Cr13) stainless steel parts. Discoloration occurs due to the formation of oxide layers,
Corrosion resistance of plasma carburized AISI 420 martensitic stainless steel was evaluated by cyclic polarization test in 3.5% NaCl solution. Two distinct treatment groups were studied with the purpose of evaluating the influence of the carburizing temperature and time on the corrosion behavior of treated material (one at 350–500 C …
The influence of low temperature plasma nitriding on the wear and corrosion resistance of AISI 420 martensitic stainless steel was investigated. Plasma nitriding experiments were carried out with DC-pulsed plasma in 25% N 2 + 75% H 2 atmosphere at 350 °C, 450 °C and 550 °C for 15 h.

Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …
In this research work, low-temperature carburizing of AISI 420 martensitic stainless steel was conducted at 460 °C for different amounts of time using an acetone source. The microstructure and phase structure of the carburized layers were characterized by optical microscope and X-ray diffraction. The properties of the carburized layers were …

Figure 2 (a) shows the XRD patterns of AISI 420 specimens nitrided at different temperatures. It can be seen that no precipitation of CrN phase was found in all specimens. The XRD patterns of the untreated specimen shows the standard α′ phase peaks (JCPDS file 44–1292). phase peaks (JCPDS file 44–1292).
