The oil and gas pipe systems are a crucial part of the infrastructure. The structural integrity of
pipes is diminishing as a result of environmental damage. In recent years, the oil and gas …

Growing demand for efficient, high-resolution surface processing has led to the emergence
of a rich variety of plasma-based technologies underpinned by an equally wide range of …

Mechanical manufacturing processes aim to transform metallic materials into mechanical
parts and components. In these processes, tools are used for cutting, punching and …

Here, pulsed plasma nitriding of AISI-316L austenite stainless steel is conducted in a narrow
range of temperature 510-550° C and simultaneous combination of expanded austenite …

The paper concerns the effect of annealing time and temperature on the properties of the
nitride layer on X37CrMoV51 tool steel used in the extrusion aluminium industry. Samples …

Microalloyed steels have been studied not only by the advent of the pre-salt, but also by the
continuous search for improvement of their tribological properties. In this work, the influence …

Despite the AISI 304 stainless steel has high corrosion/oxidation resistance, its tribological
properties are poor, being one of the barriers for use in severe wear applications. Thus …

Plasma nitriding is a plasma-activated thermochemical method widely used to increase the
fatigue strength, hardness and wear resistance of low-alloy steels. In this work, a new …

Centrifugal pumps are prevalent for many different applications in the industrial or other
sectors. The paper reviews the literature available on the improvement of efficiency of …
