The aim of the current work was to analyse impact salt bath nitriding on behavior tribological characteristics and surface microstructures AISI 316L stainless steels. Nitriding carried out at 580°C for 10 h. tribological, structural before after compared. microstructures, characteristics, as well its hardness, were investigated using optical microscopy (OM), X-ray diffractometer (XRD), profilom...

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 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...

In this paper, we report the numerical calculations for a thermo-optical model and the temperature sensitivity of a fiber Bragg grating (FBG) sensor. The thermally-induced behaviors of a FBG sensor in the gas nitriding process were analyzed for temperatures ranging from 100–650 ◦C. The FBG consisted of properly chosen photosensitive fiber materials with an optimized thermo-optic coefficient. Th...

31CrMoV9 and 34CrAlMo5 are high-performance steels used in many industrial applications which machines components exposed to high surface stresses dynamic loads. Depending on the customer needs, these first machined CNC then their surfaces hardened by nitriding. After nitriding, grinding is needed reduce roughness values of product according demand or need production. Grinding a chip removal pr...
