Demands to the application of these prostheses require hard and tough materials like cobalt-chrome alloys or ceramics. The cutting process is governed by static as well as dynamic interactions between the process and the structure of the workpiece. These interactions deteriorate the work result, especially the shape accuracy. The deflection of the milling tool is one effect, which has a significant influence. However, the deflection can be minimised by optimising the manufacturing strategy, by an adjustment of the process parameters or by optimising the tool path, which leads to an increased quality of the final product. The work presented in this paper aims to establish a connection between tool deflection and resulting form deviations during micro-milling of defined geometries in CoCr alloys. This is achieved by measuring the active forces while machining an defined test geometry with different feed rates and radial infeeds and a subsequent evaluation of the resulting form. Furthermore, the influence of the workpiece geometry on the forces and form deviations is analysed to serve as a foundation for future optimisation steps. In order to quantify the surface quality, white light interferometry is applied to measure the surface roughness Sa and Sq and the influence of feed rate vf and radial infeed ae on the surface roughness is derived.","PeriodicalId":14170,"journal":{"name":"International Journal of Nanomanufacturing","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48005173","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 effects of ZrO2 content on solution properties, mechanical properties and crystallisation behaviours as well as related morphology were systematically evaluated. The scanning electron microscopy (SEM) was used to investigate the effect of ZrO2 content on the morphology of PVDF/PAN/ZrO2 composite fibrous membranes, which showed that the diameter is only 0.8 μm when the ZrO2 is 0.4%. It could be attributed to the enhancement of solution conductivity by ZrO2 addition. Nitrogen adsorption based on Brunauer-Emmett-Teller (BET) principle was employed to measure the specific surface area, which indicated that the specific surface area increased about 1.8 times for composite membranes compared to the PVDF/PAN membrane when the ZrO2 content was 0.4%. The tensile strength of fibrous membranes increased from 2.74 of pure PVDF/PAN to 5.11 MPa of PVDF/PAN/ZrO2 when the ZrO2 content was 0.4%. The differential scanning calorimetry (DSC) results showed that the crystallinity and orientation enhanced with increasing of ZrO2, which was beneficial to improve the tensile strength. The Tg and Tc shifted to high temperature with ZrO2 increases, which demonstrated that ZrO2 promoted the heterogeneous nucleation and formed perfect crystal structure.","PeriodicalId":14170,"journal":{"name":"International Journal of Nanomanufacturing","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46274679","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 photocatalytic films were characterised by the scanning electron microscopy (SEM), X-ray diffraction (XRD), photoluminescence (PL), and UV-vis diffuse reflectance spectra (UV-vis DRS). The SEM result showed that AgVO3/TiO2 NACF exhibited a well nanorod array structure, and some AgVO3 nanocrystals were deposited on the TiO2 nanorods. The novel AgVO3/TiO2 NACF showed the enhanced visible photocatalytic activity for degradation of methyl orange (MO) compared with the pure TiO2 nanorod array film. The deposition of AgVO3 nanocrystals on the TiO2 nanorod array led to the improved visible light absorption of the composite film due to the narrow bandgap of AgVO3 (less than 2.5 eV). The contact of AgVO3 and TiO2 resulted in the formation of semiconductor heterostructure, which led to the enhanced separation of photogenerated carriers. The improved visible absorption and efficient separation of photogenerated electron-hole pairs should result in the higher visible activity of composite film compared with pure TiO2 nanorod array film.","PeriodicalId":14170,"journal":{"name":"International Journal of Nanomanufacturing","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44501590","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 properties of the as-prepared β-AgVO3 nanobelts were investigated by the characterisations, such as scanning electron microscope (SEM), X-ray diffraction (XRD), and UV-vis diffuse reflectance spectrum (UV-vis DRS). As shown by the SEM results, the obtained nanobelts showed an ultralong length of hundreds of micrometres and the width in the range of about 60-350 nm. The surface of nanobelt was also very smooth. XRD result exhibited that the AgVO3 nanobelts had a β crystal phase. By the virtue of pumping filtration of AgVO3 nanobelts solution and corresponding post processing, the flexible AgVO3 nano paper was prepared successfully. The AgVO3 nano paper exhibited a well flexibility and photocatalytic activity determined by the degradation of rhodamine B (RhB) under the visible light (λ > 420 nm) irradiation. The possible mechanism for the photocatalytic degradation of RhB by AgVO3 was also proposed correspondingly. It is hoped that the synthesised flexible AgVO3 nano paper would also have the other applications in the fields, such as Li-ion battery, gas sensing, super capacitor, and so on.","PeriodicalId":14170,"journal":{"name":"International Journal of Nanomanufacturing","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45481321","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}
