Effects of anionic monomer type of water-reducing admixture on fresh properties, compressive strength and water adsorption of self-compacting concrete J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-11-05 Süleyman Özen; Muhammet Gökhan Altun; Ali Mardani-Aghabaglou; Ayda Ünlü; Kambiz Ramyar
Abstract In this study, the effects of anionic monomer functional group type of the water-reducing admixture (WRA) on the fresh properties and compressive strength of self-compacting concrete (SCC) mixtures were investigated. Nine types of polycarboxylate ether-based high-range WRAs with the same main chains but different anionic monomers linked to the main chain were synthesized and used in different

Effect of material position on microstructure and mechanical properties of friction stir welded dissimilar austenite–ferrite stainless steels joints J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-11-05 Guolin Guo; Yifu Shen; Kehan Wu; Yuxiang Yan
Abstract The friction stir welding of 304 austenitic stainless steel and 430 ferritic stainless steel was performed by placing 304 plate on advancing side and retreating side of the tool, respectively. The results indicated that when the 304 plate was placed on advancing side, the weld metal showed superior flow characteristics and better material mixing compared to the weld when the 304 plate was

Macro- and microstructure analysis and mechanical characteristics of thick AlMg5 alloy plates joined by floating-bobbin friction stir welding J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-11-03 Mansour Mardalizadeh; Mohammad Ali Safarkhanian; Mehrdad Khandaei
Abstract The present paper explores the simultaneous influence of rotational and traverse speeds on the macrostructure, microstructure, and mechanical characteristics of welds produced by the floating-bobbin friction stir welding of 20-mm-thick AlMg5 alloy plates. The macrostructure results revealed that the visual quality of the welds was reduced with an increase in the rotational speed due to the

Improved mechanical properties of resistance welded joints of thermoplastic composites by versatile graphene oxide J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-11-02 Xuhai Xiong; Daosehng Wang; Rong Ren; Pu Zhao; Xu Cui; Shude Ji
Abstract An approach of adding graphene oxide (GO) nanosheets to enhance the joints for resistance welding glass fabric reinforced polyetherimide (GF/PEI) laminates was proposed in this study. The GO nanosheets were introduced and dispersed uniformly into the heating element (HE) of carbon fiber (CF) bundles coated PEI and the welding adhesives of PEI films in the different weight ratios. The GO nanosheets

Adhesion performance of UHMWPE fiber treated with polyethylene wax grafted methyl methacrylate alone or in conjunction with silane coupling agent J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-10-30 Yonglong Tian; Lamei Guo
Abstract To improve the interfacial adhesion between ultrahigh molecular weight polyethylene (UHMWPE) fiber and epoxy resin, the fiber were treated with polyethylene wax grafted methyl methacrylate (PEW-g-PMMA) alone or in combination with silane coupling agent. The factors affecting the interfacial bond property of fiber, e.g. grafting rate, coating temperature, concentration of silane coupling agent

Effects of the target-to-substrate distance on the microstructure and properties of TiN coatings fabricated by pulse-enhanced vacuum arc evaporation J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-10-27 Yinghe Ma; Kexin Zhang; Jianguo Yang; Xiubo Tian; Chunzhi Gong; Wenjian Zheng; Yanming He; Zengliang Gao; Lianfeng Wei; Paul K. Chu
Abstract Pulse-enhanced vacuum arc evaporation (PEVAE) is promising in surface engineering and produces coatings with better structure and properties. In PEVAE, the target-to-substrate distance (D t-s) affects the substrate ion current and ion bombardment energy which is closely related to the structure and properties of the coatings. In this work, TiN coatings are deposited on high-speed steel (HSS)

Microtensile bond strengths of short surface-coated intraradicular posts J. Adhes. Sci. Technol. (IF 1.365) Pub Date : 2020-10-24 Britta Werner; Peter Pfeiffer; Mutlu Özcan; Ibrahim Nergiz; Petra Schmage
Abstract Actual endodontic and reconstructive concepts require posts. In this trail short posts with a coronal retentive head received tribochemical-surface coating (Tbc). The microtensile-bond-strengths (μTBS) of the new short posts with and without additional coating were compared with the conventional posts concerning post and luting material.
