“…Numerous research studies in the recent years, including own studies [5,[26][27][28][29][30][39][40][41][42][43][44][45][46][47][48][49][50][51], concerning deposition using coatings resistant to the wear of tool ceramics, have verified the existing stance that it is unsubstantiated to coat tool ceramics due to their high hardness. It has been demonstrated that it is clearly reasonable to coat such tools as, first of all, the life of tools' cutting edges is enhanced by decreasing the heat emitted while cutting, by reducing a friction force on the flank surface and, secondly, it was noted that coatings, by covering pores on the surface of tool ceramics, eliminate places where fractures occur and moreover, they delay the diffusion wear process.…”

“…The methodology and detailed results of particular investigations of mechanical and functional properties of sintered tool materials with PVD and CVD coatings are presented in the own works published earlier [5,[26][27][28][29][30][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. The scientific aim of this paper is to present investigations into the structure and properties and to identify wear mechanisms for tools fabricated from the investigated sintered tool materials, which-to some extent-are newly created with newly developed nanocrystalline multiphase and graded coatings applied by PVD with cathodic arc evaporation techniques, as well as by a high-temperature CVD process, with the intention to improve the cutting properties of the investigated materials by considerably improving the life of the tool cutting edge.…”

This chapter presents a general characteristic of sintered tool materials, in particular sintered sialons, nitride ceramics, injection-moulded ceramic-metallic tool materials and cemented carbides and a general characteristic of their surface treatment technology and especially chemical vapour deposition (CVD) and physical vapour deposition (PVD) techniques. The results of our investigations in technology foresight methods concerning the development prospects of surface engineering of sintered tool materials are presented. In the next subsection, we discuss the outcomes of multifaceted research carried out with advanced materials engineering methods, including high-resolution transmission electron microscopy, into the structure and properties of multicomponent, graded and multilayer coatings on the investigated tool materials, including the newly developed injection moulded ceramic-metallic tool materials. Special attention was drawn to a one-dimensional structure of the studied PVD and CVD coatings and its impact on the properties of coatings.Keywords: sintered tool materials, foresight, surface engineering, PVD, CVD, coatings, nanostructure General characteristic of sintered tool materialsPowder metallurgy has found widespread applications in the manufacture of sintered tool materials.

Advanced sintered tool materials, due to the character of their work and complex wear mechanisms to which cutting tool edges are subjected, should satisfy numerous requirements including, in particular, high hardness, high impact strength, resistance to complex wear (adhesive, diffusive, abrasive and thermal wear) and to high temperatures, high compressive strength, stretching, flexing and bending, high fatigue and thermal strength, good conductivity and thermal capacity, cutting edge stability and good ductility [1][2][3][4][5][6][7][8]. A tool material with universal applications should merge the mentioned properties as far as possible and especially the highest wear resistance and hardness with high strength and good ductility accompanied by chemical inertness towards the workpiece. Despite the intensive development of materials engineering, a tool material has still not been produced which fulfil such requirements due to a fundamental contradiction between such properties as hardness and ductility.As mentioned in the Introduction section, in general-in the group of sintered tool materialsone can distinguish super hard sintered materials, mixe...

“…The largest contribution of the steel composition relates to the effect of alloying elements on the microstructure, which determines most of the mechanical properties of the final product. The influence of the chemical composition of steel WMDs on Charpy V impact properties has been carefully analysed over the last 15 years [8][9][10]. The influence of the steel alloying elements classifies them into two groups: carbideforming elements and elements that do not form carbides.…”

The goal of this paper is to analyse the mechanical properties of the weld steel structure of car body truck frames following MAG welding repairs using various filler materials. The main role of welding conditions is connected with filler materials, welding technology, stress state and temperature. In the paper, the properties of steel structures after MAG welding with microjet cooling are presented. Weld metal deposits (WMDs) were prepared by using various welding wires with different chemical compositions. A WMD with various nickel content was examined using three different welding wires; simultaneously, a WMD with varied oxygen content was examined using different gas mixtures for microjet cooling. In this study, the metallographic structure and impact toughness of welded joints were analysed in terms of welding parameters. The amount of acicular ferrite (AF) in WMDs, with various amounts of nickel and oxygen after welding, was tested. The various steel deposits were checked with the variable content of manganese and silicon, as well as nickel. Gas mixtures of argon and carbon dioxide were used for microjet cooling.

“…Choosing the suitable material and a good understanding of various processing methods to form products with required properties are fundamental factors to decide the right manufacturing methods [11][12][13][14][15][16]. The counter electrode is prepared by depositing a thin layer of platinum catalyst on a TCO glass substrate, but it is also one of the factors that significantly increase productions costs.…”

The paper presents the results of the structure investigation of a counter electrode in dye-sensitized solar cells using the carbon nanomaterials. Solar cells were fabricated on the glass with transparent conductive oxide TCO (10Ω/sq). Nanocrystalline titania based photoanode was prepared by spreading TiO 2 paste onto TCO glass and subsequently annealed at 450°C for at least 30 min to convert anatase phase and make an interparticle network. After then the nanostructured titania films was immersed into an ethanolic solution of the ruthenium-based dye. As a counter electrodes of dye-sensitized solar cells composite films of carbon nanomaterials and polystyrene sulfonate doped poly (3,4-ethylenedioxythiophene) PEDOT-PSS (Sigma-Aldrich) were deposited onto TCO substrates. Because carbon nanoelements and titanium oxide consist of nano-metric structural units to determine the properties of the cells and their parameters several surface sensitive techniques and methods, i.e. Raman spectroscopy, Scanning Electron Microscopy (SEM), High-Resolution Transmission Electron Microscopy (HRTEM), and electric properties of conductive layers were used.
