Copper plating was performed on nickel substrate by means of the potentiostatic electrodeposition method from a sulphate electrolyte solution. The copper coatings morphology was studied by means of the optical and ...

The steel production is one of the major sources of heavy metals emissions to the environment. There are several possibilities for prevention and minimization of these pollutants. Emission reduction measures focus on ...

The performance of any solar energy system depends very much on the availability of solar radiation and the orientation of solar collectors. Solar collectors need to be inclined at the optimum angle to maximize the ...

The paper presents the casting art of bells, their spiritual significance, as well as their evolution over time. The bells may be made of both metallic or/and nonmetallic materials, of various shapes and sizes. While ...

The paper presents the results of the analyses conducted using the SEM-EDX and micro-FTIR co-assisted techniques, on several metallic artefacts unearthed during the excavations at the (L)Ibida archaeological site in Slava ...

The fretting corrosion behaviour of untreated Ti-6Al-4V alloy in artificial saliva solution was evaluated based on the change in open circuit potential (OCP) measured as a function of time. Fretting corrosion experiments ...

This paper presents researches made on a system of monitoring and other parallel systems for diagnose used in a cold rolling mill. The first system (with specific measurement sensors) is an online vibration monitoring ...

Hard coatings are often used for mechanical properties such as wear and friction resistance. The corrosion behaviour may also be an important criterion for industrial applications of these coatings. In this paper, the ...

The experimental research was at the basis of the hot immersion coating technology with Sn-Pb alloy of the steel bands presented in the study. The characterization of these layers was achieved through microscopic analyses ...

In this paper is a study the influence of the material and heat treatment on the changes of the fine structure parameters of the superficial layer of triboelements during the first cycles of rolling contact process. The ...
