Special Issue Information

Dear Colleagues,

Following the successful first edition, we would like to invite you to submit your work to this Special Issue, “Advances in Thin Film Transistors: Properties and Applications Volume II”. Recently, transparent oxide semiconductors (TOSs) have been the object of extensive research in various connected fields. Owing to their advantages of high mobility, good transparency, and ideal uniformity, TOSs are more suitable for the application of thin-film transistors (TFTs) than conventional Si TFTs. In addition, the features of a low-temperature process and their compatibility with flexible electronics enable TOSs to become the mainstream channel materials in next-generation flat panel displays, such as active-matrix liquid crystal displays (AMLCDs) and active-matrix organic light-emitting diodes (AMOLEDs). Both In2O3 (~3.7 eV) and Ga2O3 (~4.9 eV) with wide energy band gaps possess excellent transparency. By adjusting to each stoichiometry, indium-based transparent conducting oxide materials have been widely used in flat panel displays and optoelectronic devices, among other applications. Thin-film transistors (TFTs) have been in extensive use as on/off switch and current driving devices for various applications, ever since the concept of TFTs was reported. This Special Issue of Coatings, “Advances in Thin Film Transistors: Properties and Applications Volume II”, aims to cover recent advances in TFT technologies.

This study applied plasma transferred arc (PTA) welding to fabricate hard cladding layers by using nickel-based superalloy (NCR7) and niobium carbide (NbC) powders as filler material. The resultant composite claddings were coated onto ductile iron and then analyzed to understand the effect of different quantities of NbC on the solidification structures of the cladding layers and on the characteristics of the interface between the cladding layers and the ductile iron. Cutting tests were also conducted to assess the morphology and mechanism of flank wear on PTA NbC/NCR7 composite cladding tools. The results revealed that the cladding specimens’ microstructures comprised a mixture of dendrites and interdendritic eutectics along with a considerable quantity of carbides (MC, M7C3, and M23C6) scattered within the γ-Ni matrix. Incorporating considerable NbC carbide enhanced the claddings’ surface hardness, but it had a limited effect on improving the flank wear on the turning tools. The flank wear on the composite cladding tools intensified as the NbC content was increased. The wear behavior, defined by brittle fractures and stripped NbC particles, led to a decline in turning tool performance. Accordingly, the Ni-based alloy composite cladding with larger NbC particles appears more suitable for sliding or erosion applications under normal stress conditions. Full article
