A theoretical approach to the rational choice of technological combinations that allow create optimal structures on surface steel products can effectively resist wear and fatigue is considered. An example a highly efficient combined process including laser alloying nitriding given. The application principles structural theory strength makes it possible purposefully form complex multifactorial p...

The ion nitriding behavior of AISI 316L austenite stainless steel was investigated at different times (2 h, 4 and 9 h) temperatures (450 °C, 500 550 °C). structural characterization has been assessed by several considerations which can be listed: (i) the evaluation phase distribution through Rietveld analysis X-ray diffraction patterns accompanying peak fitting process, (ii) hardness profile re...

Active Screen Plasma Nitriding (ASPN) is a well-established technique used for the surface modification of materials, the result of which is often a product with enhanced functional performance. Here we report the modification of the chemical and mechanical properties of ultra-high molecular weight poly(ethylene) (UHMWPE) using 80:20 (v/v) N2/H2 ASPN, followed by growth of 3T3 fibroblasts on th...

The results of modifying the surface austenitic stainless steel by anodic plasma electrolytic treatment are presented. Surface was carried out in aqueous electrolytes based on ammonium chloride (10%) with addition ammonia (5%) as a source nitrogen (for nitriding), boric acid (3%) boron boriding) or glycerin carbon carburizing). Morphology, roughness, phase composition and microhardness diffusio...

The aim of this work was to study the microstructure and friction coefficient hybrid surface layers, produced by a controlled gas nitriding laser modification. Nitriding is well-known technique thermo-chemical treatment, applied in order produce layers improved hardness wear resistance. phase composition growth kinetics diffusion layer can be using with changeable potential. 42CrMo4 steel treat...
