Effects of different starting materials, such as powder and cutting chips of Mg, on the properties were investigated. The influence of sintering holding times on the properties was also investigated to establish between the process conditions and the properties. Hardness testing and X-ray diffraction were carried out for characterization of powders and bulk materials. The results of hardness indicated that MM-SPS process can synthesis upgrade recycled material fabricated from Mg cutting chips. In the case of cutting chips, the maximum hardness was observed at 6 hours of MM and 60 min of sintering holding time. On the other hand, in the case of powder showed the maximum hardness at 6 hours of MM and 10 min of sintering holding time. However, the hardness did not increase with increasing sintering holding time. No solid-state reaction was observed in SPS materials fabricated from powder and cutting chips. In addition, no contamination of impurities during MM treatment was observed.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"22 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136227970","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}

We have developed a method to control the orientation by applying a strong magnetic field during colloidal processing. In this study, we have demonstrated that suspensions with dispersed agglomeration-free nano particles can be produced by beads-milling HAP particles with zirconia beads as small as 0.05 mm. By slip casting in a high magnetic field and sintering using suspensions with dispersed agglomeration-free nano particles, high-density and oriented sintered bodies were successfully fabricated at low temperatures.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184622","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}

A film forming process utilizing the electrophoretic phenomenon of charged particles in a liquid is called “electrophoretic deposition (EPD)” and is used for powder coating. The main difference between the EPD process and other colloidal processes is the coexistence of electrode reactions, ie electrochemical reactions that occur at the interface between the electrode and the electrolyte solution. The applied electric field in the EPD method plays an important role not only in the electrophoresis of charged particles but also in controlling the coagulation mechanism and film quality. This paper introduces the principle of the EPD process considering the electrode reaction and an example of the functional film formation process.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184607","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}

Nondestructive inspection by evaluating defects inside sintered bodies, dynamic changes in particle sedimentation and drying processes in ceramic slurries, quantitative evaluation of pore structures in dry forming under applied stress, and visualization of internal structures under high temperature in dewaxing and sintering are enabled.
