Abstract: The work presents the microstructure, chemical composition and mechanical properties of Inconel 686 coatings after high - temperature corrosion in environment of aggressive gases and ashes. To produce the Ni - based coatings the QS Nd:YAG laser cladding process was carried out. As the substrate used 13CrMo4-5 boilers plate steel. [..] Read more

Abstract: Inhibition of stainless and mild steel corrosion in 1 M HCl solution by 1-octyl-3-methylimidazolium bromide and 1-dodecyl-3-methylimidazolium bromide was investigated using electrochemical and weight loss methods. The qualitative surface analysis was carried out. [..] Read more

Abstract: The influence of surface preparation of steel 41Cr4 on the structure and corrosion resistance of the zinc coating has been presented in the paper. The aim of the study was to determine the method of surface preparation fittings for overhead power lines made of steel 41Cr4 guaranteed to obtain zinc coating of a required thickness and high corrosion resistance.

Abstract: Secondary phase’s precipitation is dangerous for stainless steel. The most important secondary phases for stainless steels with carbon amount higher than 0.2 % are carbides (especially M23C6). [..] Read more

Abstract: A number of modern surface processing methods use an energy flux. The examples include electro-spark deposition (ESD) and laser processing (LP). [..] Read more

Abstract: The corrosion resistance of aluminum-silicon (Al-Si) foundry alloys is a result of microstructure development influenced by melt treatment and solidification. As a part of the main eutectic (αAl + βSi), βSi particles are cathodic with respect to the αAl matrix enabling micro-galvanic couple formation and localized corrosion. [..] Read more

Abstract: The use of salt mixtures properties is considered in many future technologies, such as energy storage or medium for nuclear reactors. The key question is to choose a suitable construction material for these devices operating at high temperatures in a corrosive environment. [..] Read more

Abstract: Magnesium alloys are characterized by high corrosion rates. This undesirable phenomenon can be slowed down by corrosion inhibitors. [..] Read more

Abstract: Currently, there is increasing pressure to reduce waste generation and to use it as a secondary raw material. In the framework of this work, there are presented beginning parts of the project plan called "Research of processing of metallurgical waste, materials and by-products from metallurgical and related operations number CZ.02.1.01/0.0/0.0/17_049/0008426“.

Abstract: Crack initiation of the ferritic martensitic steel T91 and austenitic steel 316L is currently under study. This is due to the evaluation ongoing in the EC for materials compatibility in Heavy Liquid Metals (HLM) environment, and, in particular, the issue of Liquid Metal Embrittlement.Slow Strain Rate Tensile (SSRT) tests were performed with flat specimens in PbBi at 300°C with oxygen content in the range of about 10-6 wt.% down to 10-12 wt.% and, for comparison in air, up to the point of maximal stress (without or with minimum necking).

Abstract: The development of Generation IV nuclear reactors and accelerator driven systems (ADS) is supporting a wide range of work on the compatibility of stainless steels with heavy liquid metals (HLM).The austenitic steel DIN 1.4970 (also known as 15-15Ti) is being qualified for use in heavy liquid metals because of its lack of sensitivity to Liquid Metal Embrittlement. The aim of this study is to look into cracking modes and their main characteristics in order to reach a clear idea of mechanisms.Flat tensile, tapered specimens were loaded in PbBi at 300 °C with low oxygen content and, for comparison in air, up to the Ultimate Tensile Stress, UTS, point and rupture.

Abstract: HCM in Miasteczko Śląskie is the only zinc smelter in Europe which use Imperial Smelting Process technology. Paper shows ISF charging model which allows to calculate on-line current state of the furnace batch parameters. [..] Read more

Abstract: One of the currently used industrial methods of zinc and lead production is Imperial Smelting Process, based on the use of a shaft furnace. It was created for the processing of traditional minerals of both metals that form compounds with sulfur. [..] Read more

Abstract: The ferritic martensitic steel T91 is among the candidate materials for internal structural components of future Heavy Liquid Metal cooled reactors. The position of T91 on the list of the candidate materials is now being questioned due to the evidence of its sensitivity to liquid metal embrittlement (LME), mainly in PbBi eutectic. [..] Read more

Abstract: The production of iron in blast furnaces involves a number of entirely different processes such as: chemical, mechanical, and physical. The input materials often contain several negative elements, such as heavy metals. [..] Read more

Abstract: The content of the paper is a brief description of the basic characteristics of the reactive diffusion in the dissolution of solid copper in the melt of tin solder. Furthermore, it deals with the theory of growth kinetics of intermetallic phases during heat treatment, and a description of lead-free solders and related problems during soldering. [..] Read more

Abstract: Slags formed during pyrometallurgical extraction of zinc and lead contain numerous metals, and can provide a valuable source of these. Metal recovery from Zn-Pb slags can be accomplished using a pyrometallurgical method consisting in recovering materials at sufficiently high temperatures by transferring them to specific condensed phases (including metallic alloys) or the gas phase with subsequent condensation.
