The paper is dedicated to the life prolongation of tools designed for deep-hole drilling. Among available methods, an ion implantation process was used improve durability tungsten carbide (WC)-Co guide pads. Nitrogen fluencies 3 × 1017 cm−2, 4 cm−2 and 5 were applied, scanning electron microscope (SEM) observations, energy dispersive spectroscopy (EDS) analyses, X-ray photoelectron (XPS) Secondary Ion Mass Spectrometry (SIMS) measurements performed both nonimplanted implanted tools. tests...
Orbital angular momentum (OAM) of light appears when the phase an electromagnetic wavefront winds around its direction propagation, also known as optical vorticity. Contrary to binary-valued photon spin, integer-valued vortex charge is unbounded with many advantages in communication and trapping enhancing capacity data encoding multiplexing. Singular optoelectronic chiroptic quantum technologies rely on development coherent compact sources well-defined reconfigurable OAM. We propose...

This work explores an effect of nitrogen ion implantation on the life time WC-Co tools used in particleboard milling. Nitrogen ions with different energy 5, 50, and 500 keV fluence 1e17 5e17 cm−2 were implanted into surface commercially available composite indexable knives, using implanters mass-separated beams. Both untreated modified samples subjected to microstructural durability tests. Microstructural tests involved observation, determination nature wear cracks, element depth profiles,...
The paper presents the preliminary results of cellulose modification by ion implantation. Three types ions were implanted, i.e., copper, zinc and silver with fluences 5 × 1014 1015 cm−2, respectively. acceleration voltage implanted was 30 kV. penetration depth profiles showed differences, especially in Cu Ag cases, due to different beams these elements. implantation clearly changed wettability material surface direction hydrophobicity. impact on growth mold fungi also noticeable. Only had a...
The paper presents the effect of nitrogen ion implantation on tool life tools commonly used in furniture industry for drilling particleboards. Nitrogen ions with different accelerating voltages 25, 40, 55, and 70 kV a fluence 5 × 1017 cm-2 were implanted into surface commercially available high-speed steel (HSS) drills, using implanters without mass-separated beams. tests carried out computerized numerical control (CNC) machining center industry. Based measurements direct wear indicator (W),...
