A series of Ti/Ti-diamond-like carbon (Ti-DLC) films was deposited onto monocrystalline Si substrates by dual-magnetron sputtering. The mechanical properties, chemical composition, and microstructure the were investigated Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), diffraction (XRD), nanoindentation. biocompatibility Ti-DLC evaluated via cell viability testing. TiC phase formed at a Ti content 4.43 atom %, surface roughness gradually...
To extend the service life of 316L stainless steel components in harsh environments, this study utilized laser cladding technology to enhance hardness, wear resistance, and corrosion resistance surface. Nickel-based cobalt-based layers were prepared on surface steel, microstructure phases analyzed using scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, photoelectron spectroscopy. In addition, hardness substrate was tested with a microhardness tester, frictional...
Abstract The ester base oil of dioctyl adipate (DOA) was oxidized in an oven at 200 °C for 30 h, and variations the physicochemical tribological properties were studied. To investigate thermal-oxidation mechanism, products analyzed by gas chromatography–mass spectrometry (GC−MS), process simulated using visual reactive force field molecular dynamics (ReaxFF MD). results indicated that total acid number (TAN) increased significantly because presence 14% carboxylic acids low weight monoesters....
A high-performance liquid chromatography method coupled with photo array diode detector has been developed and validated for simultaneous quantification of 11 active alkaloids in Rhizoma Coptidis (R.C.). The analysis was performed on a Benetnach-C18 column (250 × 4.6 mm, i.d., 5 μm) using binary gradient elution 30 mmol/L ammonium bicarbonate water containing 0.7% ammonia solution 0.1% triethylamine (A) acetonitrile (B) at flow rate 1 mL/min, temperature 35°C UV detection 275 nm. All...
Abstract This paper aims to develop a chromium‐free chemical conversion coating with good corrosion resistance. A novel was prepared on 6061 aluminum alloy by dipping in the treatment solution containing titanium/zirconium based‐ions and sodium metaphosphate cerium nitrate hexahydrate as additives. The morphology composition of coatings were observed scanning electron microscopy energy dispersive X‐ray spectroscopy. microarea structure at different formation stages analyzed probe...
Purpose This paper aims to investigate the tribological behavior and online infrared spectra of three types lubricating oils containing dinonyl diphenylamine (DNDA) antioxidant, which are mineral oil (MO), poly alpha olefin (PAO) trimethylolpropane trioleate (TMPTO), during friction process at high temperature (temperature rising first isothermal holding afterwards). Design/methodology/approach A platform low speed four-ball tribometer equipped with a controller combined spectrometer was...
Purpose This paper aims to focus the synchronous chemical conversion technology–based titanium/zirconium composite on 6061, 7075 aluminum alloys and galvanized steel. Design/methodology/approach The effects of pH, temperature, reaction time other process parameters corrosion resistance three metal surface coatings were investigated by copper sulfate drop electrochemical performance tests under a certain content H2TiF6 H2ZrF6. morphology element distribution coating analyzed scanning electron...
Although the application of electrical neuromodulation has yielded promising results, further studies such as optimising operational parameters are necessary. Due to fact that most commercially available stimulators not suitable for animal experiments in terms size, weight and structure, a programmable implantable neurostimulator treating chronic disorders freely behaving small animals is developed this reported study. This stimulator was compatible with different applications reserved ports...
Although the reason is not clear, mileage commonly recommended as an indicator to evaluate oil drain interval of a car. This paper tries investigate whether most suitable based on scientific experiments and data analysis method. Three civilian cars motor oils (contained mineral oil, semisynthetic synthetic oil) were subjected road tests under urban traffic condition. The real-time driving parameters comprising speed, mileage, idle time, engine operation number starts obtained by on-board...
Abstract As oxidation stability of engine oil was hard to evaluate in field, this paper tried propose a field test method determine the onset temperature (OOT) gasoline oil. A theoretical model grey average value spot image and OOT established by using method, processing, Pressure Differential Scanning Calorimetery method. The sample unknown taken processing obtain value. can be calculated bringing model. This approach successfully used for determination 4 different kinds oils with good...
