The response of the human Jurkat T cell leukemia-derived cell line (Jurkat T cells) after 24 h of in vitro exposure to a titanium substrate (12 × 12 × 1 mm³) with a bilateral rough (Ra = 2.2-3.7 μm) titanium oxide coating (rTOC) applied using the micro-arc method in a 20% orthophosphoric acid solution was studied. A 1.5-fold down-regulation of hTERT mRNA expression and decreases in CD3, CD4, CD...
Right angle magnetron sputtering (RAMS) was used to produce hydroxyapatite (HA) film coatings on pure titanium substrates and oriented silicon wafer (Si(0 0 1)) substrates with flat surfaces as well as engineered surfaces having different forms. Analyses using synchrotron XRD, AFM, XPS, FTIR and SEM with EDS showed that as-sputtered thin coatings consist of highly crystalline hydroxyapatite. Th...
The aim of the research work was to characterize soldering alloy type Bi-Ag-Ti and study direct silicon copper. Bi11Ag1.5Ti solder has a broad melting interval. Its scope depends mainly on content silver titanium. begins melt at temperature 262.5 ?C full is completed 405 ?C. microstructure consists bismuth matrix with local eutectics. crystals titanium phases as BiTi2 Bi9Ti8 are segregated in m...
The oxidation of titanium substrates in the air under laser irradiation is investigated. experimental dependence TiO2 layer thickness on number pulses subjected to comprehensive analysis. prevailing chemical and physical processes substrate surface near-surface are determined. It found that drives surface-energy induced mixing substrates. rate sharply depends temperature. This allowed detect ex...
This work aims to study the cytocompatibility of protective coatings obtained in argon and nitrogen atmospheres on a TiNi surface. Particular attention is paid comparing interaction cell culture with an uncoated sample, using for comparison number viable cells surface, phase composition, structure, wettability, surface charge topography. The Ti/Ni/Ti nanolaminate was deposited substrate by magn...
BACKGROUND Titanium is an inert metal that does not induce osteogenesis and has no antibacterial properties; it is proposed that hydroxyapatite coating can enhance its bioactivity, while zinc can contribute to antibacterial properties and improve osseointegration. AIMS A nano-sized hydroxyapatite-zinc coating was deposited on commercially pure titanium using an electro-chemical process, in or...
