“…Besides, several CVD and PVD coatings are deposited onto hardmetals as films with total thickness around 4-20 μm e.g. [40][41][42], which provide excellent wear resistance in spite of their rather limited thickness.…”

The effect of a nitridation surface treatment on the microstructure and corrosion resistance of Co and Ni-binder (W,Ti)C-based hardmetals with additions of (Ta,Nb)C was investigated. Nitridation treatment produces a surface layer with a higher hard phase (Ti,Ta,Nb,W)(C,N) content. The near-surface layer thickness and microstructure are affected by the choice of binder (Co respectively Ni). The corrosion resistance of the hardmetals was characterized using linear sweep voltammetry. The microstructure of the hardmetals was determined before and after corrosive attack by optical microscopy and SEM. The results of the corrosion tests and microstructure analyses are interpreted in terms of the correlation between the hardmetal morphology and porosity and ion transport through the interface binder-electrolyte. The nitridation treatment of the hardmetals strongly increases the resistance to aggressive corrosion media for hardmetals both with Co and Ni-binder phase and thus may positively influence the hardmetal lifetime in cutting applications in chemically aggressive environments.

“…From the viewpoint of film-forming, in Inconel 718 turning, the (Ti, Al)N-multilayer coating showed some performance advantage over the (Ti, Al)N-monolayer at higher speed [8]. Nowadays, most multi-layer coating materials contain a combination of TiN, TiC, Ti(C,N) and Al2O3; to improve the tool life, they are deposited in different sequences [9].…”

-As we know the cutting tool is an important basic tool required in metal removal operations for producing the components. It not only produces component but also maintains the dimensional accuracies, geometrical tolerances and desired surface finish of the machined part. Machining is important in metal manufacturing process to achieve near-net shape, also for the aesthetic requirements. The latest machining process and using the CNC machine tools the cutting tool play a vital role. The manufacturers of these components expect to improve their productivity, quality of the components and longer life of the cutting tools. The longer life of the cutting tool depends on various factors like machine tools used for the machining operation, cutting conditions, work piece material hardness and tool wear etc. In order to meet all these tasks the cutting tool manufacturers in the process of producing quality tools to withstand for higher cutting forces, thermal resistivity with more wear resistance. Many reputed cutting tool manufacturing organisations globally with their rich experience of research and development, invented different ways of enhancing the life of cutting tool in order to optimize the rate of production and to reduce the cost of production, which is highly accepted by the manufacturing industry. The continuous inventions in developing cutting tool materials and coatings on these materials in improving the wear resistance of the cutting tool is in progress day by day. One of the main pre-requisites for successful industrial production is the use of quality coated cutting tools with defined mechanical and technological properties. Therefore, for the development and introduction of new coated cutting tool (new combination of cutting material and hard coatings), it is necessary to carry out a number of studies with the purpose to optimize the coatings composition and processing procedures, and also to test new tools in working conditions.The requirement from the manufacturing industry is produce faster, better, safety and more ecologically, force us to develop new effective tools and innovative technologies. This provides a technological challenge to the scientists and engineers and increases the importance of knowing several scientific disciplines In this paper the analysis is made for the performance of various coated carbide cutting tools in machining the steel AISI 1018. In this review, the machining performance of coated tungsten based cemented carbides, were investigated during finish turning of AISI 1018 steel under dry conditions.
