Abstract: The influence of the nature of organic additives on the rate of low-temperature chemical deposition of nickel is studied. The class of organic compounds allowing to obtain adhesion coating of chemical nickel was revealed. [..] Read more

Abstract: Geo-components are manufactured from steel, galvanized steel and polymers commonly take the form of reinforcing meshes, straps or strips for high quality erosion and sediment control systems. Prediction of durability of zinc/zinc alloyed coatings can be done on the basis of knowledge of their thickness and zinc/zinc alloyed corrosion rate in soil. [..] Read more

Abstract: Magnesium and its alloys are considered for specific applications in medicine such as fixation devices, screws and stents. However, release of hydrogen gas, pH increase and premature failure of the mechanical integrity of implant material are considered as the main limitations. [..] Read more

Abstract: Acoustic emission (AE) has been used to study magnesium alloys for many years. The advantage of AE is getting the data from the entire volume with high time resolution. [..] Read more

Abstract: The article presents the results of corrosion tests of multi-groove pads made with the MIG method on a C45E steel substrate. The process of welding the multi-groove pads was carried out with constant parameters of the pad-welding process (i.e. [..] Read more

Abstract: To describe a surface morphology of textured polymer coatings, the model of polymer chains attached to spherical granules was developed. By means of the model, we revealed the influence of coating density on its surface morphology. [..] Read more

Abstract: Bioactive coatings can be divided into two main groups - organic and inorganic coatings. Hydroxyapatite (HA) is well known as one of inorganic part of mammal’s bone structure and is highly recommended for use in implantology. [..] Read more

Abstract: In this study, the impact of corrosion in S400 grade of reinforcing steel bar as for the mechanical performance on seismic loads (low-cycle fatigue LCF) was investigated. The mechanical performance and life expectancy of S400 grade of reinforcing steel bar on seismic loads was evaluated based on the strength degradation (reduction of maximum strength) during its loading time period, under corrosion or not circumstances.

Abstract: This paper assesses the possibilities of graphitic cast iron parts and components of hydraulic turbines. The experimental program evaluated the behavior of spheroidal and vermicular graphite under conditions which simulated challenging work environment hydraulic machines. [..] Read more

Abstract: The paper describes the corrosion resistance comparison of hot-dip zinc galvanized cast iron with flake graphite in relations to bronze. The practical application of investigated cast iron is planned as a materials for fitting elements working in corroding medium of sea water. [..] Read more

Abstract: Stainless steels are promising materials for fuel cell bipolar plates. It meets high demands for bipolar plates, good thermal and electrical conductivity, low cost, good mechanical properties. [..] Read more

Abstract: The specific feature of modern Russian paintwork material (PWM) market is an import share rise along with foreign manufactures extensive expansion. Russian market range of PWM contents above 3000 items, considering both PWM being used in household and foreign products. [..] Read more

Abstract: Corrosion - mechanical damage of the economizer pipe of the biomass boiler was analysed. Macroscopic, microscopic and SEM-EDX analysis were used for the analysis of steel samples. [..] Read more

Abstract: Recently, as an alternative to chromate protective layers at aluminum and its alloys, worldwide are used nanoscale adhesive coatings, obtained from hexafluorozirconic and hexafluorotitanic acids. The present study is devoted to the technology of development of these coatings.The process of deposition of titanium, zirconium-containing coatings at aluminum alloy 5556 is developed. [..] Read more

Abstract: The disadvantage of magnesium alloys is their low corrosion resistance due to high electronegativity. One of the most effective methods to improve the corrosion resistance of magnesium alloys is to form a conversion adhesive coating on their surface, followed by applying paintwork materials. [..] Read more

Abstract: The aim of this study is to compare the corrosion resistance of anodic oxidation coatings on Al2024 alloy. Due to its composition with a high content of alloying elements (mainly Cu), anodization of this alloy is one of the difficult ones compared to most other alloys or pure aluminium. [..] Read more

Abstract: In recent years, there has been an increased interest in technologies for the production of titanium ceramic materials with properties, the level of which in terms of price-quality ratio exceeds the level of similar materials based on other metals. The strength of the bond with the metal in modern titanium ceramic products corresponds to the level of cermet systems based on noble metals or alloys without them. [..] Read more

Abstract: This poster focuses on the characterization of chloride migration from the environment into different types of concrete. Chloride diffusion into reinforced concrete plays an important role in the degradation of reinforced concrete structures. [..] Read more

Abstract: Nowadays, implants are predominantly made of metallic materials that have two main problems. The first resides in the modulus of elasticity being higher than the one of the human bone (10-20 GPa), resulting in stress shielding and subsequent implant failure. [..] Read more
