Increase of pollution in recent years, requires monitoring of the corrosion behavior of artistic bronzes coated with syntetic patina, in urban atmosphere. This present work aims to investigate the corrosion rezistance ...

This paper presents the influence of adding materials (micros glass spheres) in a matrix of PBT on several mechanical properties: elasticity modulus, stress at break , elongation at break, energy at break. The mechanical ...

Properties of refing slags belonging to the system CaO-MgO-Al2O3-SiO2 are important in simultaneous or succesive refinig treatment processes in the ladle and other refing metalurgical reactors. The efficiency of treatments ...

This paper is a study on the problem of using ultrasound in the treatment of raw water. It highlights the effect of ultrasounds produced by the experimental sonic ultrasound generator through the physico-chemical analysis ...

The paper presents results of a study undertaken to implement the dental casting technique of small parts characterized by extremely complex drawings of surfaces and thicknesses reduced specific objects. During the study ...

The characterization of iron ore particles is of vital importance for the study of mineral composition. The specific surface area of iron ore particles can be measured by laser diffraction, and mathematical models (based ...

In this paper we show an integrate system of water management and an efficient solution that is a floating dock, placed in the harbour area. Water quality is one of the most important elements for life support and ...

The need to develop products with special characteristics and high mechanical properties led to the introduction of plastic deformation of semifinished materials. Special purpose products are produced from slabs, ...

The goal of this document is to promote a sequence of bulk-deformation processes able to produce ultrafine grain and also nanostructured wires with adequate length to be interesting for processing in metallurgical industry. ...

In this paper is a study of the influence of steam treatment on sintered P/M steels, for three different types of powder. The abrasive wear of steam-treated sintered iron is analysed by abrasion tests. The specimens were ...
