The paper proposes a new technology for fluid production intensification, in particular
hydrocarbons, which is implemented via significant increasing of the local wellbore diameter …

Drilling volumes should be increased in order to increase hydrocarbon production, but this is
impossible without the usage of high-quality drilling tools made of modern structural …

The special features of thick combined electrospark coatings (СESC) formed on cylindrical
12Kh18N10T stainless steel samples are analyzed. The samples were carbonized with the …

The work presents an analytical study of" crosshead-slide rail" wear effect on stress state of
a double piston pump's rod. The authors proposed an engineering model of pump's rod …

The analysis of manufacturing defects of functional surfaces showed that traditional
technologies do not provide a sufficient level of quality required for their manufacture …

This article deals with improving the wear resistance of multilayer coatings as a fundamental
problem in metal surface treatment, strengthening elements of cutting tools, and ensuring …

The work presented in this paper is devoted to the formation of thick-layer wear-resistant
coatings by technologies based on electrospark alloying, an example of essential …

The reasons for reducing the durability of sliding bearings and the factors formed both at the
stage of their manufacture and during operation are considered. Taking into account the …

The quality parameters of surface layers synthesised using electrospark alloying (ESA)
technology were analysed in this paper. The main focus was on the influence of equipment …

There is proposed a new process for nitrocarburizing steel parts by the method of
electrospark alloying (ESA), which includes applying a paste-like nitrogenous component to …
