In this study, vanadium conversion coating(VCC) was deposited on the surface of soft-cast steel (St-37).  A thermoset coating was enforced on the VCC and blank substrates. The surface was characterized by field emission scanning electron microscope (FE-SEM), elemental mapping of energy dispersive X-ray (EDX) and atomic force microscopy (AFM). The adhesion strength...

This study was conducted to evaluate the bioactivity of manganese-incorporated TiO2 (Mn-TiO2) coating prepared on titanium (Ti) plate by plasma electrolytic oxidation (PEO) technique in Ca-, P- and Mn-containing electrolytes. The surface topography, phase and element compositions of the coatings were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispe...

in this research, tribological behavior of ti-ni-p intermetallic coatings on titanium substrates have been investigated under dry reciprocating conditions. hardness profile testing results exhibit that high surface hardness has been attained and static indentation result shows that the intermetallic coating has better adhesion strength than the conventional ceramic coatings. in this respect, th...

Chitosan based nanofibers containing carbon nanotubes were applied on AZ31 magnesium alloy via electrospinning. The magnesium substrate was initially anodized in a NaOH solution in order to improve the adhesion between the coating and substrate. Electrospinning parameters were optimized and homogenous nanofibers composite coatings were produced. Addition of carbon nanotubes reduced the size of ...

Poly(glycolic acid) (PGA) fibers are a good candidate material for nerve cell scaffolds, which is applicable to the treatment of peripheral nerve injuries. Polylysine is widely used as a coating material for cell substrates to promote nerve cell adhesion. In this study, linear and dendrigraft polylysines were used to coat PGA fibers. The association of large dendrigraft polylysines with PGA fib...

The characteristics of ink vehicle absorption into porous structures has formed the basis of a number of recent studies. Kalela, Ridgway and Gane (11th International Printing and Graphic Arts Conference, Bordeaux, 2002) considered an example of common impression cylinder deposits as a result of poor coldset ink adhesion especially in the presence of excess fountain solution. These studies centr...

Magnesium alloys as biodegradable metal implants have received a lot of interest in biomedical applications. However, magnesium alloys have extremely high corrosion rates a in physiological environment, which have limited their application in the orthopedic field. In this study, calcium phosphate compounds (Ca-P) coating was prepared by arginine-glycine-aspartic acid-cysteine (RGDC) peptide-ind...

Hydroxyapatite (HA) has been used in clinical bone graft procedures for the past 25 years. Although a biocompatible material, its poor adhesion strength to substrate makes it unsuitable for major loadbearing devices. Investigations on various deposition techniques of HA coating on Ti–6Al–4V implants have been made over the years, in particular to improve its adhesion strength to the metal alloy...

Silver-PTFE metal matrix composite coatings were deposited onto ANSI 304 stainless steel to assess the potential of using a novel non-cyanide electroplating process to produce a corrosion resistant, self-lubricating composite coating. During this study, 32 different bath parameter sets, derived from 5 variables were used to develop the non-cyanide electroplating process without the use of a sur...
