Rock breaking has always been a challenging problem that must be solved in projects such
as excavating mountains, drilling wells, and constructing railways. Among the rock-breaking …

Machining cemented carbide coating on workpiece surface can effectively improve wear
resistance of friction pair and reduce frictional coefficient and frictional wear. Through the …

An analysis of common reinforcement methods of machine parts and theoretical bases for
the selection of their chemical composition were carried out. Prospects for using flux-cored …

In this article, an analytical approach to the study of the behavior of functionally graded FG
coatings under local load is developed. The method is suitable for coatings with a specific …

Optimization of drilling processes for oil and gas and geothermal wells requires the effective
use of mechanical energy for the destruction of rocks. When constructing a well, an …

In the long-term use of high manganese steels, it is not desirable to achieve wear resistance
by austenite deformation strengthening alone. The wear resistance of high manganese steel …

A new hardfacing alloy within the Fe-Ti-Nb-Mo-VC alloying system was utilized to restore the
working surfaces of cone crusher rotors using Flux-Cored Arc Welding (FCAW). TiC, NbC …

The size effect of impact abrasive particles on wear and surface hardening behavior of high-
manganese steel was studied. Impact wear tests were carried out on MLD-10 tester with …

In the conditions of an energy crisis, an important issue is the increase in energy efficiency
and productivity of welding and hardfacing processes. The article substantiates the …

Shot peening technology is usually employed to improve the ability of mechanical parts to
resist failure due to fatigue and wear. It is often used to strengthen the surface of a target, but …
