Corrosion behavior of ion nitrided stainless steels (SS) containing Mo was investigated by electrochemical methods. The morphologies of ion nitrided stainless steel were analyzed using optical microscopy and scanning electron microscopy (SEM). Pitting corrosion resistance is improved remarkably in the case...
If necessary, Al2O3 layers 5 are formed on the surfaces, respectively, by further exerting heating under an oxidizing atmosphere. By this method, the corrosion resisting Mo member can be produced.YAMADA HIROSHIYAHAGI SHINICHIRO
Seawater corrosion-resistant welding procedure of 00Cr18Ni14Mo2Cu2 austenitic stainless steel was studied. By improvement of welding procedure, width of heat-affected zone (HAZ) was reduced, difference of chemical constitution between HAZ and fusion zone(FZ) was minished, metallurgical structure of...
(3)腐蚀(corrosion)是指金属在其周围环境的作用下引起的破坏或变质现像。从不同角度,曾对腐蚀下过不同的定义,如: 1)材料因与环境反应而引起的损坏或变质; 2)除了单纯机械破坏之外的一切破坏; 3) 冶金的逆过程 4)材料与环境的有害反应 0cr16ni5Mo是一种马氏体/铁素体的不锈钢。 一、0cr16ni5Mo对应牌...
Corrosion behaviour 1. Introduction Titanium (Ti) alloys have been widely employed in the marine, biomechanics, desalination of seawater, offshore drilling and chemical industry, due to their desirable properties of high strength to weight ratio, great biocompatibility and excellent corrosion resistance ...
For use in making components which are required to have a very high resistance to uniform corrosion and against pitting and crevice corrosion under very highly corrosive conditions encountered in up to date chemical process technology and environmental protection technology, for instance, in flue gas ...
The results of this testing indicate that it is unlikely to stress corrosion crack this alloy in presence of chlorides at temperatures in the range of atmospheric boiling (≈100°C). At temperatures greater than 120°C cracking can be initiated depending on the chloride content of the ...
A process and an alloy are provided for producing high strength material having good ductility to provide a high strength, corrosion resistant alloy including the steps of (1) preparing a body of material having a composition consisting essentially of by weight, about 13% to 18% chromium, about...
The corrosion resistance of commercial austenitic alloys in the Fe-Cr-Ni-Mo system in marine environments has been reviewed. The types of corrosion examined include intergranular corrosion, stress-corrosion cracking, corrosion fatigue, pitting, crevice corrosion, galvanic corrosion, cavitation damage, and...
A comparison has been made of the corrosion fatigue behaviour of a low-alloy rotor steel in aqueous and hydrogen environments. Cracks were grown under conditions of constant alternating stress intensity and stress ratio, and fatigue crack growth rates were determined as a function of temperature, cy...
