Owing to its superior tribological and mechanical properties with corrosion resistance, biocompatibility, and hemocompatibility, diamond-like carbon (DLC) has emerged as a promising material for biomedical applications. DLC films with various atomic bond structures and compositions are finding places in orthopedic, cardiovascular, and dental applications. Cells grew on to DLC coating without an...

Since dental implants are used in contact with many different tissues, it is necessary to have optimum surface compatibility with the host bone tissues and soft tissues. Furthermore, dental implant surfaces exposed to the oral cavity must remain plaque-free. Such materials can be created under well-controlled conditions by modifying the surfaces of metals that contact those tissues. “Tissue-com...

Ca-P and silicon based materials have become very popular as bone tissue engineering materials. In this study, water-glass (also known as sodium silicate glass) was coated on sintered hydroxyapatite (HA) and HA-TCP (TCP stands for tricalcium phosphate) samples and subsequently heat-treated at 600°C for 2 hrs. X-rays diffraction showed the presence of β- and α-TCP phases along with HA in the HA-...

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...

Adhesion and homogeneity of the coating-substrate were analyzed on basis establishment coating mineralogy. Substrate raw materials used kaolin clay a calcined alumina 4 µm; series higher density ceramic coatings deposited using aluminas 0.5 µm µm, silica fume, talc. The dip technique was applied to all substrates later sintered at 1300 ºC. Shrinkage mixtures substrate separately evaluated. X-ra...

Different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. The coatings were applied on low carbon steel plates. Optical microscopy, sedimentation test, transmission electron microscopy, and X-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. The corrosion resistance of coatings was evaluated by electrochemical...

Diamond-like carbon (DLC) coatings are used due to their extraordinary tribomechanical properties, great hardness, high elastic modulus, wear resistance, low friction coefficient and chemical inertness, which provide them with biocompatibility. Compared other physical vapor deposition (PVD) of transition nitrides carbonitrides, DLC has limited adhesion, so it is necessary develop new techniques...
