Machine parts and tools of various shapes and sizes are nitrided, including drills, cutters, dies, shafts, rings, bearing balls, etc. often characterized by a complicated shape. The nitrided layers should have a controlled thickness not only of the diffusion zone, but also the surface layer of iron nitrides to have good exploitation properties. With a properly prepared surface on low alloy steels, we obtain a uniform nitrided layer after nitriding. It may happen that the structure of the nitrided layer is heterogeneous or even completely lacking in the nitrided parts having a complicated shape, and especially thin inner openings, where it is difficult to properly prepare the surface. Therefore, the nitriding problem is not the external surface of the workpieces but the internal one. The aim of the work was to assess the possibility of nitriding deep holes with small diameter. The tests were carried out on cylindrical specimens of unalloyed and low-alloy steel with electro-bored and mechanically hollow through holes and blind holes. The quality of the obtained nitrided layers was evaluated by metallographic and hardness examinations.\u0000\u0000","PeriodicalId":348539,"journal":{"name":"Inżynieria Powierzchni","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127820664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coatings of zirconium oxynitride have been deposited by the method of cathodic arc evaporation onto steel substrates. A set of coatings obtained at different relative volumetric concentrations of oxygen in the reaction atmosphere during deposition has been investigated. The influence of oxygen concentration on the colour, surface morphology and phase composition of the coatings has been analyzed. With the increase of oxygen content, the colour of the thin Zr-O-N coating has changed from golden-yellow to graphite. Observation of the surface of the coatings by means of the SEM method has shown the presence of surface defects in the form of macroparticles ranging from a submicron to several micrometers, with the smallest microparticle population being the largest. It has also been found that the surface roughness of the Zr-O-N coatings increases as the relative volumetric concentration of oxygen in the atmosphere during deposition increases. By means of X-ray diffraction analysis it has been shown that the zirconium oxide phase has occurred with a relative oxygen concentration of 50%, whereas below this value only the ZrN phase has been observed. The value of the parameter of the regular elementary cell of the Zr-O-N coatings increases as the relative concentration of oxygen in the atmosphere increases, while at the same time the intensity of the diffraction lines of the coatings decreases.\u0000\u0000","PeriodicalId":348539,"journal":{"name":"Inżynieria Powierzchni","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128353696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of nitrogen pres-sure and substrate bias voltage on the properties of CrAlN coatings formed from Al80Cr20 cathode, such as: chemical and phase composition of the coatings, their surface morphology, deposition rate, hardness and adhesion to the substrate have been investigated. It has been determined that the rate of the deposition of coatings in the nitrogen atmosphere with the pressure of 3 Pa is the highest and that with the increase of the negative bias voltage of the substrate the deposition rate decreases. The roughness parameter Ra of the coating surface decreases as the nitrogen pressure increases during their formation. Presumably, this is related to the reduction of the amount of macroparticles on the surface of the coating. The hardness of the coatings (taking into account the measurement uncertainty) is independent of the nitrogen pressure, but it increases with the increase of the negative bias voltage of the substrate. The adhesion of the coating increases with the increase of the nitrogen pressure to 3–4 Pa, and then it decreases. The increase in the negative bias voltage of the substrate during the formation of the coating deteriorates its adhesion to the substrate.\u0000\u0000","PeriodicalId":348539,"journal":{"name":"Inżynieria Powierzchni","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122032531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
