“…In case of PVD TiB 2 , the origin of these stresses can be mainly attributed to irradiation of the growing film by energetic ions and/or neutrals [4,5,19]. In contrast, the widely used hard coatings based on TiCN or Al 2 O 3 grown by CVD on cemented carbide substrates typically exhibit tensile residual stresses, which are mainly due to the difference in thermal expansion coefficients of coating and substrate material [20]. However, CVD TiB 2 coatings have been reported to show compressive residual stresses although their thermal expansion coefficient is larger than that of the substrate [3,21].…”

“…The hardness data of the coatings and cementite are collected from the literature [10,17,18]. The temperature-dependent hardness for three coatings (TiN, TiCN and alumina) and the abrasive (cementite) are also collected and presented in Table 2.…”

“…[5,6] In the case of a chemical coating, there are many methodologies, such as vapor deposition, [7][8][9] spraying, [10][11][12] roll-to-roll coating, [13,14] and chemical/electrochemical techniques, to modify and control the surface properties of the substrates for further applications. The concept of coating is also important for the development of biological and tissue engineering fields, for example, surface control of a protein or polymer to control cell adhesion, [15] growth direction, [16,17] or even killing specific bacteria and making a biosensor chip.…”

Living tissues or organ modules consist of different types of highly organized cells and extracellular matrices (ECMs) in a hierarchical manner, such as the multilayered structure of blood vessels and the radial structures of hepatic lobules. Due to animal examinations being banned in the EU since 2013 and a shortage in the demand for tissue repair or organ transplantation, the creation of artificial 3D tissues possessing specific structures and functions similar to natural tissues are key challenges in tissue engineering. To date, we have developed a simple but unique bottom-up approach, a hierarchical cell manipulation technique, with a nanometer-sized ECM matrix consisting of fibronectin (FN) and gelatin (G) on cell surfaces. About 10 nm thick FN/G ECM films on cell surfaces were coated successfully by using layer-by-layer coating methodology. Various 3D constructs with higher cell density with different types of cells were successfully constructed. In addition to the construction of tissues with higher cell densities, other tissues, such as cartilage or skin tissues, with different cell densities are also important tissue models for tissue engineering and pharmaceutical industries. Thus, we recently developed other methodologies, the collagen coating method and multiple coating method, to fabricate micrometer-sized level ECM layers on cell surfaces. Various micro- or millimeter-sized 3D constructs with lower cell densities were constructed successfully. By using these two methods, cell distances in 2D or 3D views can be controlled by different thicknesses of ECM layers on cell surfaces at the single-cell level. Both FN/G and the collagen coating method resulted in homogenous 3D tissues with a controlled layer numbers, cell type, cell location, and properties; these will be promising to achieve different goals in tissue engineering.
