Tankerler, Tehlikeli Maddelerin Karayolunda Taşınmasına ilişkin Avrupa Anlaşması’na (ADR) tabiidir. Tankerlerin üretiminde AISI 304, 321 ve 316Ti kalite östenitik paslanmaz çelikleri plazma kaynak yöntemi ile birleştirilmektedir. Tankerler taşıdıkları ürünlere bağlı olarak farklı sıcaklıklar altında yüklere maruz kalmaktadır. Bu çalışmada, bölgelerinin 80°C 150°C 250°C mekanik özellikleri çekme...

In this paper we study the corrosion of AISI 304 austenitic stainless steel PEMFC bipolar plates in aqueous and room-temperature ionic-liquid electrolytes. The anodic potential thresholds and dynamics have been investigated by electrochemical (potentiodynamic and potentiostatic) and in situ spectroelectrochemical methods (visible electroreflectance and VIS-UV spectroellipsometry). We measured t...

Commercial rolled AISI 321 stainless steel samples were irradiated with Al+ ions an energy of 80 keV and fluence 1017 ion/cm2. The effect Al implantation on the chemical phase composition surface layer was studied by X-ray electron spectroscopy grazing beam mode diffraction analysis. A thin down to a depth 30 nm after consists mainly metal oxides. In near-surface layers 5 in depth, noticeable d...

Schrödinger-type wave equations with logarithmic nonlinearity occur in hydrodynamic models of Korteweg-type materials capillarity and surface tension, which can undergo liquid–solid or liquid–gas phase transitions. One the predictions theory is a periodic pattern density inhomogeneities occurring form either bubbles (topological phase), cells (non-topological phase). Such are described by solit...

Sol-Gel coatings are a good choice for protection and bioactivation of metals used as dentistry and standard surgical implant materials. These films should both prevent degradation of the substrates by wear or corrosion, and bioactivate the material for inducing the formation of a hydroxyapatite (HA) rich layer onto the material surface, thereby permitting a natural bonding to living tissues. T...

The paper presents results of research under the effect surface thermo-chemical treatment on cor-rosion resistance X6CrNiTi18-10 steel. corrosion layers stainless steel obtained as a result (boronizing process) was assessed using method progressive thinning, which consists in performing tests deeper and areas layer. This allowed for determination changes individual characteristic corro-sion par...

Complex two-component peak of anelastic mechanical losses was observed in multicomponent substitutional austenitic alloys after prior plastic deformation. In AISI 316L, AISI 316LN, AISI 310 and AISI 304 austenitic stainless steels, this peak is situated in the wide range of temperature from 200 to 400K. Characteristics of the observed peak for different thermo-mechanical treatments were studied...
