چکیده
Abstract The boronizing kinetics of AISI 316L steel has been analyzed by employing five prediction models. boron diffusion coefficients as well the growth rate constants in FeB and Fe 2 B phases were firstly evaluated range 1123-1223 K. Afterwards, values activation energies secondly deduced adopting Arrhenius relationships.In addition, models have validated experimentally for two conditions (1170 K 1.6 h 1210 1.1 h). predicted results deemed very concordant with experiments. Furthermore, advantages limitations about applicability these also discussed.

Biomaterial Studies on AISI 316L Stainless Steel after Magnetoelectropolishing
The polarisation characteristics of the electropolishing process in a magnetic field (MEP – magnetoelectropolishing), in comparison with those obtained under standard/conventional process (EP) conditions, have been obtained. The occurrence of an EP plateau has been observed in view of the optimization of MEP process. Up-to-date stainless steel surface studies always indicated some amount of fre...
متن کاملMicro abrasion-corrosion of AISI 316L stainless steel
In this study, the synergistic effects of abrasion and corrosion on AISI 316L stainless steel have been investigated using a micro-abrasion test rig. A series of results from abrasioncorrosion tests conducted using the micro-abrasion rig are presented. AISI 316L stainless steel has been studied under both pure abrasion and abrasion-corrosion conditions simulated by either distilled water or 3.5...
متن کاملFormation of Surface Nano/Ultrafine Structure using Deep Rolling Process on the AISI 316L Stainless Steel
Austenitic stainless steels (ASSs) have an excellent corrosion resistance but relatively-low hardness and yield strength [1,2], leading to limited usage in applications that high values of hardness and wear resistance is necessary for material surface. Therefore, surface properties such as hardness must be improved using appropriate techniques. Mechanical surface treatments such as ultrasonic s...
متن کاملAn investigation on the passivation behavior of nitrogen enriched AISI 316L austenitic stainless steel
In the present work the effects of plasma nitridization on the passivation behavior of AISI 316L was investigated. To do this; nitriding treatments were carried out at 420°C for 1, 2, 4 and 16 hours. The phase composition and structure of the nitrided layer were studied by Low Angle X-ray diffraction and Scanning Electron Microscopy. The hardness of samples also was evaluated by Vickers microha...
