Still, little attention has been paid to modifications in the tribological properties of ion-exchanged glass surfaces. This work reports on scratch testing of a chemically strengthened alkali-borosilicate thin glass. Diffusive Na+/K+-ion exchange produces a residual surface compressive layer with compressive stress of 200–340 MPa and layers depths between 16 and 50 µm, depending on exchange temperature and treatment time. This leads to notable changes in the surface mechanical properties, such as an increase in surface Young’s modulus, indentation, and scratch hardness. Surprisingly, the Na+/K+-ion exchange is shifting the onsets of scratch-induced microcracking and microcracking to lower normal loads. The ccelerated buildup of lateral indentation stress in glasses with high scratch hardness was found to be responsible for the lower threshold loads of microcracking and abrasive wear in chemically strengthened alkali-borosilicate thin glass.

In this study, strengthening of machinable zirconia/mica composites was attempted by exchanging interlayer ions of mica in composites for larger ions, like chemically strengthened glasses. So the sintering behavior and ion-exchange of the composites fabricated using swelling mica and the mechanical properties of the ion-exchanged composites were investigated. The dense composite was obtained by sintering at 1200°C for 1 min and was ion-exchanged in molten potassium salts at 800°C. Na+ ions in the interlayer of mica near surface of the composites were exchanged for K+ ions. However, K+ ions wer Chemical strengthening of zirconia/swelling mica composites by ion-exchange in molten salts | CiNii Research 検索 タイトル 人物/団体名 著者ID/研究者番号 所属機関 ISSN DOI 期間 〜 本文リンク 本文リンクあり データソース JaLC IRDB Crossref DataCite NDLサーチ NDLデジコレ（旧NII-ELS） RUDA JDCat NINJAL CiNii Articles CiNii Books NACSIS-CAT/ILL DBpedia KAKEN e-Rad Integbio PubMed LSDB Archive 極地研ADS 極地研学術DB OpenAIRE 公共データカタログ すべて 研究データ 論文 本 博士論文 プロジェクト 人物 > 人物検索機能について 詳細検索 閉じる CiNii Researchナレッジグラフ検索機能（試行版）をCiNii Labsにて公開しました 「研究データ」「根拠データ」の収録について CiNii Books機能統合対応の追加実施をいたしました Chemical strengthening of zirconia/swelling mica composites by ion-exchange in molten salts DOI オープンアクセス Yuji Takita Tomohiko Yamakami Tomohiro Yamaguchi Seiichi Taruta 書誌事項 公開日 2021-03-30 DOI 10.1080/21870764.2021.1905253 公開者 Informa UK Limited 説明 In this study, strengthening of machinable zirconia/mica composites was attempted by exchanging interlayer ions of mica in composites for larger ions, like chemically strengthened glasses. So the sintering behavior and ion-exchange of the composites fabricated using swelling mica and the mechanical properties of the ion-exchanged composites were investigated. The dense composite was obtained by sintering at 1200°C for 1 min and was ion-exchanged in molten potassium salts at 800°C. Na+ ions in the interlayer of mica near surface of the composites were exchanged for K+ ions. However, K+ ions were not inserted in the interlayer of mica. Mica reacted with molten salts to form an amorphous phase near surface of the composites. Simultaneously with the reaction, Na+ ions in mica were discharged into molten salts and K+ ions in molten salts were penetrated into the amorphous phase. Then other crystalline phases were formed in the amorphous phase. By the ion-exchange, the cracks developed from Vickers indentation corners were obviously shortened, which is one of the evidence that the compressive stress was generated near surface. By the compressive stress, the fracture toughness (3.5 MPa・m0.5) and the bending strength (322 MPa) of the composites were increased to 5.6 MPa・m0.5 and 447 MPa, respectively. 収録刊行物 Journal of Asian Ceramic Societies Journal of Asian Ceramic Societies 9 598-608, 2021-03-30 Informa UK Limited Tweet キーワード TP785-869 chemical strengthening swelling mica Clay industries.
