Nano-coatings for surface property modification
Title coatings can be applied to metals, plastics, textiles & stone to give a highly scratch-resistant surface, eliminate fingermarking from stainless steel etc & prevent staining, such as wine, from marble or other worktop surfaces. Cross-hatch test shows good adhesion to PVC film and Taber wear tests confirm good tribological properties.. www.degussa.com/creavis.de
Nano-coatings for automobile windscreens - transparent coatings for improved vision
Title coating is electrically conductive and allows a heated windscreen without visible wires.
Nano-coatings for corrosion protection
inorganic nano-particles are applied as sol-gel, then fired at 400°C for 4hrs or so. Transparent coatings such as these are shown on steel, aluminium, glass. Graphs show microhardness vs. sinter temperature and delamination kinetics vs. time. 3D Kelvin probe images also show delamination. Graphs show sintering behaviour of variously sized silica (Aerosil) particles.SEM surface images are also shown. Particle packing density is discussed, incl. that from electrophoretic dep'n. Siloxane-modified coatings are shown. Zeta potential meas'ts are discussed and formation & use of hybrid-nanoparticles. Corrosion after 1500 hr immersion in NaCl is almost nil. Sub-surface migration corrosion is shown as graph. 14 refs
Nano-coatings for mass-production
Text & photos show large scale applications, incl. kitchen cooker top surfaces (burner trays), domestic light switches, lift buttons etc, where anti-fingermarking & bactericidal actions are noted..
Nano-coatings in optics
Focus on new process which increases output of LED lamps by up to x10. www.nanogate.com
Nano-coatings transfer from automotive to architectural
Title coatings, for example on glass, incl. electrochromic are now offered for domestic & office use, as also self-cleaning and corrosion-resistant, incl. fibre-reinforced plastics then coated. 14 refs
Nano-coatings with anti-fingerprint action
The nature of fingerprints is considered and the use of textured surfaces with tiny island protrusions to break up the pattern offered as a solution. Numerous SEM photos show the effect and profilograms show how an anti-fingermarking surface can be formed. An optical sphere apparatus to quantify fingerprint effects is shown, tables show how light wavelength results are variously weighted and graph shows weighted results. 6 refs (all patents)
Nano-coatings. New functions for glassy coatings
Focus on sol-gel coatings, incl. their deposition over vitreous enamels to impart scratch and wear resistance as well as durable non-stick properties. Panel summarises sol-gel processes. Nano-sized pigments allow coloured coatings to be formed on glass, for example. Creating easy-to-clean surfaces and using sol-gels to form either hydrophilic or hydrophobic surfaces is schematised.
Nano-composite coatings with superlattices
Describes duplex or multilayer PVD coatings such as titanum nitride with Ti carbonitride over, hardness values of 500kg/sq. mm almost as hard as diamond being achieved, comparable to cubic boron nitride. Various other nitride-nitride non isostructural systems are noted.
Nano-composite multifunctional materials
Title process is broad term encompassing composite coatings based on nano-particles, ca. 10E-8 to 10E-9 metre diameter. Such coatings can be electrodeposited, or chemically or physically applied. Photos & text show examples of aluminium diecast or extruded parts, coated with nanocomposites. Sketch shows options, incl. inorganic silicon 3D networks & organic polymers, silica, titania, zirconia, ITO are among the particulate phases used. Comment on trade-marked products & processes, Ormocer(Ormocere) from Fraunhofer Ges, and Nanocere from Messrs INM GmbH. Illustrated application shows non-stick coating for colour print rollers.
Nano-composite surface for foodstuff packaging cleanliness
New class of non-stick coating for industrial food production can be spray-applied & cured at lower temperatures than PTFE. A polymer binder matrix incorporates perfluorinated comonomers & nano-sized hard particles. Polyurethane based systems performed best for abrasion & chemical resistance, but polyimide also performed well under some conditions. Taber wear results are shown, better than PTFE and hydrophobicity is maintained after wear. Table shows roughness, wear & contact angle before & after Taber tests for 8 surfaces incl. stainless steel, PTFE, epoxy, PUR matrix & other. Contact angles were meas'd by horizontal (sessile ?) drop using 5µL water or hexadecane droplet. Thermal tests had little effect on contact angles. Milk protein & vegetable juice were used to assess cleanability. 23 refs
Nano-composite TiO2-PI via sol-gel process
Case study of Finnish chilled display cabinet mfr who replaced iron phosphate conversion coating with Bonderite CC40 for one-step cleaning + conversion coating with improved corrosion resistance. On steel, after 720 hrs salt spray, underfilm creep was 1mm, over aluminium, no evidence after 1000 hrs. Effluent problems are much reduced, while energy costs can be up to 30% lower, reflecting the lower operating temperature (typically 40°C rather than 50°C). www.henkel.com
Nano-crystal diamond film, manufacturing method thereof, and device using nano-crystal diamond film.
Title film with grain size 1 to 1000nm using plasma CVD. Applications for this incl. electrochemical anodes, DNA chips, fuel cells, catalysts
Nano-crystalline coating to improve cyclic oxidation resistance of 304 stainless steel.
SURF Cyclic oxidation of nano-crystalline 304SS coating was compared with that of conventional, micro-crystalline 304SS in both dry and wet (10% H2O) air at 900 °C. The nanocrystalline alloys were prepared by direct current magnetron sputtering coating. Weight change kinetics were measured by continuous thermogravimetry. For micro-crystalline alloy in dry air, a small initial weight gain was followed by gradually increasing spallation. Addition of water vapour to air produced immediate spallation, and led to significant breakaway oxidation. Microstructural analyses revealed the formation of iron-rich oxides on the surface. The addition of water vapour also accelerated the development of internal oxidation in the form of fine spinel precipitates dispersed in the chromium depleted matrix. In contrast, nano-crystalline 304SS, underwent relatively rapid oxidation in the very early cycles of reaction, but then the reaction slowed down. No spallation was apparent in either gas. The weight gain was higher in wet air than in dry air. In both gases a dense and continuous chromium oxide layer was formed at the surface, together with other oxides distributed inside the coating layer. The effects of cyclic reaction, grain size and water vapour on the resistance of 304SS to breakaway oxidation are discussed.
