Weak cell-surface adhesion of cell lines to tissue culture surfaces is a common problem and presents technical limitations to the design of experiments. To overcome this problem, various surface coating protocols have been developed. However, a comparative and precise real-time measurement of their impact on cell behavior has not been conducted. The prostate cancer cell line LNCaP, derived from...

The stability of an electrodeposited nanocrystalline Ni-based alloy coating in a H₂S/CO₂ environment was investigated by electrochemical measurements, weight loss method, and surface characterization. The results showed that both the cathodic and anodic processes of the Ni-based alloy coating were simultaneously suppressed, displaying a dramatic decrease of the corrosion current density. The co...

In order to improve the corrosion and wear resistance of biomedical Ti-6Al-4V implants, a Ta₂N nanoceramic coating was synthesized on a Ti-6Al-4V substrate by the double glow discharge plasma process. The Ta₂N coating, composed of fine nanocrystals, with an average grain size of 12.8 nm, improved the surface hardness of Ti-6Al-4V and showed good contact damage tolerance and good adhesion streng...

The effect of different electrodeposition variables chitosan coatings on Ti-6Al-4V substrates is studied. Electrolytic solutions containing at 0.1, 0.5, and 1.0 wt/v% was used to coat grit-blasted samples through electrodeposition, 1.5 3.0 V, for 2.5, 20 30 min. Coating surface morphology analyzed by scanning electron microscopy. Adhesion behavior characterized scratch testing, coating stabilit...

A coating with thermochromic and photochromic microcapsules can enhance a product’s attractiveness. Different processes may affect the performance of coatings. Therefore, micromorphology, chemical composition, chromatic difference, gloss, hardness, adhesion, impact resistance, roughness, cold liquid ultraviolet photooxidation resistance surface on metal substrate were assessed by choosing three...

Progress on these topics is occasionally updated in Coating Materials News (CMN) issues since polymer substrates are being used with greater frequency in displays, solar panels, laminated window glazing, reflectors for illumination, and other optical applications. Injection molded or form cast polymer parts are now mass-produced as economical and light-weight replacements for glass parts. The s...

Using Electrostatic Spray Coating Technique, Polypropylene Powder (EPD 60R) was applied on carbon steel substrates at room temperature. In order to obtain a uniform coating, steel substrates with powder coatings were heated in a vacuum oven at various temperatures up to 250° C for various periods of time up to 45 min and a pressure of 200 mb. The coatings produced had thicknesses of around 470 ...
