“…Also, since the presence of the HA on the Ti‐6Al‐4V provided a similar surface chemistry to the natural bone (bone on bone), there was an improved initial cell adhesion and subsequent faster spreading and proliferation of the cells 62,86 . The cell proliferation was observed in the SEM images as shown in Figure 5.…”

Despite the attractive combinations of cell/surface interactions, biocompatibility, and good mechanical properties of Ti‐6Al‐4V, there is still a need to enhance the early stages of cell/surface integration that are associated with the implantation of biomedical devices into the human body. This paper presents a novel, easy and reproducible method of nanoscale and nanostructured hydroxyapatite (HA) coatings on Ti‐6Al‐4V. The resulting nanoscale coatings/nanostructures are characterized using a combination of Raman spectroscopy, scanning electron microscopy equipped with energy dispersive x‐ray spectroscopy. The nanostructured/nanoscale coatings are shown to enhance the early stages of cell spreading and integration of bone cells (hFOB cells) on Ti‐6Al‐4V surfaces. The improvements include the acceleration of extra‐cellular matrix, cell spreading and proliferation by nanoscale HA structures on the coated surfaces. The implications of the results are discussed for the development of HA nanostructures for the improved osseointegration of Ti‐6Al‐4V in orthopedic and dental applications.

“…The main available coating technologies for tool steels are Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD) and Thermal Spray [5]. The Halide Activator Pack Cementation (HAPC) is a process similar to CVD [6]. HAPC is useful to increase the surface properties in a very effective way [7].…”

The paper describes the pack siliconizing optimization procedure for AISI D2 tool steel. Pack siliconizing was performed by employing different treating temperatures (falling in the range 650–950 °C) and times (falling in the range 2–4 h). The siliconizing atmosphere was obtained through silicon (at 12 wt.%) with the addition of different percentages of NH4Cl (falling in the range 0.5–1 wt.%), Al2O3 was used as halide activator. The coatings’ phases evolution was analyzed through X-ray diffraction; the coatings’ thickness was measured through scanning electron microscopy observations of the cross section of the samples; the mechanical properties were evaluated through micro hardness measurements. The results showed that the coatings’ thickness and hardness increase as the treating time and temperature as well as the halide activator percentage increase. The coating procedure optimization was performed by employing the response surface methodology based on Box-Behnken method. The results of the optimization procedure led to the of the optimal combination of processing parameters: 1 wt.% of halide activator, 3.575 holding time, 950 °C in temperature.

“…Moreover, because of the bio-inert character of natural thin TiO 2 films, it takes months until osseointegration sets in, thus prolonging the duration of the prosthetic treatment by up to several months. A number of studies have been conducted to overcome this problem by inducing bioactive property and enhancing the bone-implant adhesion through the surface modification of titanium implants [4,5]. Because such an implant surface accelerates osseointegration and enhances bone-implant adhesion, various surface-treatment methods have been studied, including surface coating, surface microstructure modification, and chemical property modification [6][7][8].…”

The aim of this study is to enhance the bioactivity of pure titanium using multiple surface treatments for the application of the implant. To form the biofunctional multilayer coating on pure titanium, anodization was conducted to make titanium dioxide nanotubes, then multi-walled carbon nanotubes were coated using a dipping method after an alkali treatment. The surface characteristics at each step were analyzed using a field emission scanning electron microscope and X-ray diffractometer. The effect of the multilayer coating on the biocompatibility was identified using immersion and cytotoxicity tests. Better hydroxyapatite formation was observed on the surface of multilayer-coated pure titanium compared to non-treated pure titanium after immersion in the simulated body fluid. Improvement of biocompatibility by multiple surface treatments was identified through various cytotoxicity tests using osteoblast cells.
