Emisja uciążliwych zapachów pochodzących z nieruchomości sąsiednich, np. z zakładów przemysłowych, ubojni czy spalarni lub współspalarni odpadów, może stanowić nie lada problem. Zdarza się też, że przykry zapach wynika z zaniedbań właściciela w kwestii utrzymania niezbędnej czystości i sprawności urządzeń sanitarnych, przetrzymywanych zwierząt lub stanu budynku. Niezależnie od źródła tej uciążliwości, osobom dotkniętym taką immisją służą środki prawne na jej zawalczanie.

Purpose: This paper presents investigation of gradient coating of (Ti,Al,Si)N deposited on the Al2O3+SiC(w) oxide ceramics substrate deposited with the PVD process. Design/methodology/approach: Structure of substrate and coating was investigated with use of scanning electron microscopy (SEM); The X-Ray Photoelectron Spectrometry (XPS) and Auger Electron Spectrometry (AES) examinations was carried out for proving the gradient character of the (Ti,Al,Si)N coating. The investigation includes also microhardness and roughness tests of the deposited coating and used substrate. Scratch test results was analysed to introduce adherence of the investigated coating. Findings: Gradient structure and main properties of the investigated materials were introduced. It has been stated, that properties of the coated with gradient (Ti,Al,Si)N coating oxide tool ceramic increase in comparison with uncoated material. Practical implications: Depositing the wear resistant gradient coating onto the Al2O3+SiC(w) oxide tool ceramic results in a significant increase of the surface layer microhardness, contributing most probably in this way in machining to the decrease of the wear intensity of cutting tools’ flanks made from the Al2O3+SiC(w) oxide tool ceramic. Originality/value: Gradient coatings are an innovative idea. The composition, microstructure and properties of gradient materials change continuously from the surface to the interior of the material.

Purpose: Investigation of gradient coating of (Ti,Al,Si)N deposited on the Al203+SiC(w) oxide ceramics substrate by cathodic arc evaporation CAE-PVD method. Design/methodology/approach: Structure of substrate and coating was investigated with use of scanning electron microscopy (SEM). The X-Ray Photoelectron Spectrometry (XPS) examination was carried out for proving the gradient character of the (Ti,Al,Si)N coating. The investigation includes also microhardness and roughness tests of the deposited coating and used substrate; The Ra surface roughness parameter measurements were made on confocal microscope. Findings: Gradient structure and main properties of the investigated materials were introduced. It has been stated, that properties of the oxide tool ceramic with gradient (Ti,Al,Si)N coating increase in comparison with uncoated material. Practical implications: Depositing the wear resistant gradient coating onto the Al203+SiC(w) oxide tool ceramic results in a significant increase of the surface layer microhardness, contributing most probably in this way in machining to the decrease of the wear intensity of cutting tools' flanks made from the Al203+SiC(w) oxide tool ceramic. Originality/value: Functionally gradient coating form is a new class of structures in which the microstructure and properties vary gradually from the surface to the interior of the material.
