The corrosion rate and corrosion attack characteristics were determined for thirteen commercially available materials exposed in a geothermal production well for three months. The materials included carbon steels, Cr-Mo alloy steels, martensitic and ferritic stainless steels, high-nickel alloys, and titanium. The environment at the 1800 ft (600 ...
In the present study, the microstructure, mechanical property, castability, corrosion behavior and in vitro cytocompatibility of binary Ti-2X alloys with various alloying elements, including Ag, Bi, Ga, Ge, Hf, In, Mo, Nb, Sn and Zr, were systematically investigated, in order to assess their potenti …

The corrosion inhibition effect of Sida cordifolia extract, a perennial subshrub of the mallow family Malvaceae, has been examined on mild steel corrosion in 0.5 M H2SO4 by using weight loss ...
The three important factors in seawater corrosion include chloride concentration, oxygen and temperature. When it comes to corrosion engineering, seawater is one of the most important environments to discuss. This may be especially true when it comes to pipelines, which crisscross the ocean carrying oil and gas worldwide—and which, of course ...
The results of the screening tests of the aluminide coating are promising but its behaviour in the long-term will be analysed in LIFUS II during and at the end of the experimental campaign. Dissolution effect will be monitored on-line by Al analysis on the melt sampled before and after the cold trap.
However, because immunotherapy drugs are newer, there is not as much information about long-term effects of exposure. To be safe, many experts recommend treating immunotherapy drugs as hazardous and taking the same precautions. This is especially true when immunotherapy drugs are given to treat cancer in combination with other drugs that are ...
The effect of different organic inhibitors on the corrosion rate of Cu in 0.01 M FeCl 3 solution was investigated using potentiodynamic polarization tests (Fig. 3a).
In the present study, the microstructure, mechanical property, castability, corrosion behavior and in vitro cytocompatibility of binary Ti-2X alloys with various alloying elements, including Ag, Bi, Ga, Ge, Hf, In, Mo, Nb, Sn and Zr, were systematically investigated, in order to assess their potential applications in dental field.
1. Introduction. Physical, chemical and/or electrochemical annihilation of a material by its atmosphere is termed corrosion [].Corrosion is initiated due to electrons' movement from one material to another or a receiver material [].The corrosion of iron, de-alloying of aluminum, rusting of steels, pitting of alloys and stainless steels in salt containing media and …

As indicated in the last column of Table 1, the usefulness and applicability of the various standard test methods varies.Also, in assessing the test results it is necessary to compare the types of accelerated corrosion …
Comprehensive screening of corrosion inhibitors. ... (Fig. 3B) after 3, 7, 14 and 30 days' immersion at 37 °C in SBF were in line with the conclusion drawn in the above electrochemical tests. The two coated samples have a lower corrosion rate than that of the substrate. ... Evaluation of the anti-corrosive effect of acid pickling and sol ...
As indicated in the last column of Table 1, the usefulness and applicability of the various standard test methods varies.Also, in assessing the test results it is necessary to compare the types of accelerated corrosion attack with those caused by natural/outdoor environments [].This aspect is particularly relevant to exfoliation corrosion testing of Al–Li alloys, for which …
Purpose – Rapid manufacture‐produced cobalt chromium alloys are beginning to be used in dentistry but there are few published results relating to their properties. The purpose of this paper is to determine the corrosion resistance of a rapid manufacture‐produced dental alloy and compare it to a standard dental casting alloy. Design/methodology/approach – In …
Pinnock, T., Voordouw, J. & Voordouw, G. Use of carbon steel ball bearings to determine the effect of biocides and corrosion inhibitors on microbiologically influenced corrosion under flow conditions.
The objectives of this work are to determine the emulsion tendency of VCI at varying concentrations, and the effect of VCI dosage on corrosion of X65 carbon steel exposed to top as well as bottom ...

This study examined the effect of corrosion on mechanical properties of welded carbon steel pipe in district heating water. To evaluate the corrosion properties, potentiodynamic tests were conducted and a galvanostatic test was used to accelerate corrosion. Tensile tests and microstructure observations were performed to figure out the …
53. o All reactors were filled with oil tested according to ASTM D 1275 and the result was "non corrosive". o After appoximately 6 month in service some units of North/South line filled with oil "A" presented corrosive sulfur when tested with the same method. o Units filled with oil "B" did not test positive for corrosive sulfur ...
Published online 2018 Nov 9. ... Out of the four biocides tested, the inhibition effect of BAC against IS5 corrosion was most effective out of the all biocides tested because of the lowest anodic and cathodic reaction rates as well as the smallest corrosion current density. The inhibition effect of GLUT was smallest, as both the anodic and ...
CORROSION INHIBITOR SELECTION STRATEGY FOR OILFIELD PIPELINES 2.5 The "bubble test" is a simple sparged beaker test which can be set up reasonably quickly and so it is ideal for rapidly carrying out a large number of tests such as, for example, in the first stage of corrosion inhibitor selection, or for screening a wide range of field ...
AISI H13 die steel specimens were subjected to heating at 1020 °C followed by oil quenching and double tempering at 520 °C. Subsequently, these specimens were subjected to deep cryogenic treatment at −185 °C in liquid nitrogen environment for 16 h and then subjected to soft tempering at 100 °C once the specimens attained room temperature. …
The article, "External and Internal Corrosion Detection Sensors for Oil and Gas Pipelines Using Fiber Optics," written by Dr. Nader Vahdati and company in 2018, presents a detailed study on the technology provided by Fiber Bragg Grating, which is based on the use of a permanent magnet.
