Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • An experimental study on global contact stiffness of sandy particle layers under high loads in three body contact   Order a copy of this article
    by The Y. Doan  
    Abstract: In this work, the stress-strain behaviour of particle layers, namely, global contact stiffness is investigated by a series of uniaxial compressing tests. In our experiment, one up to three layers of quartz sand grade HB 34 are pressed between a block of steel and a rotating steel disk with the applied load varying from 0.03 kN up to 20 kN. The stiffness of abrasive layers depends on different parameters such as the applied loads, the thickness of the layers and the loading-unloading process. The dependency of the contact stiffness on normal loads and on different compression test conditions is studied. Based on the global stiffness of the particle layer, the local contact pressure in the contact zone can be estimated. We have built a uniaxial spindle tester and carried out various experiments. Accordingly, some mathematical expressions of contact stiffness in terms of applied loads in loading, unloading process were derived by regression algorithms.
    Keywords: contact stiffness; three-body abrasive wear; mathematical modelling; experimental investigation.

  • Development of burnishing process using free-ball tools for surface modification and improvement of corrosion resistance of inner wall of water channels of die-casting moulds   Order a copy of this article
    by Masato Okada, Reyu Yamamoto, Yuji Kobayasi, Yuta Saito 
    Abstract: A burnishing process that use free-ball tools on the inner surface of a drilled hole was developed to prevent surface cracking and corrosion in the cooling water channels of die-casting moulds. In the developed burnishing process, a pressure bar with a hammering mechanism is used to apply impact forces to multiple hard balls placed in the target hole. The resulting compressive forced achieve surface modification at multiple contact points between the free-ball tools and inner surface of the target hole. These contact points are changed by stirring the ball tools, thereby applying a burnishing effect to the entire inner surface of the hole. Moreover, zinc powder is interposed between the free-ball tools and target surface, where it adheres to the target surface and improves the corrosion resistance.
    Keywords: surface modification; corrosion-resistance treatment; burnishing process; free-ball tools; surface profile; hole inner surface; hardened die steel; water channels; die-casting mould.

  • Effect of an iron-enriched aluminum surface fabricated via fine particle peening on tribological behavior under oil lubrication   Order a copy of this article
    by Yutaka Kameyama, Jun-ya Tachizawa, Kazuki Seo, Ryota Shimazaki, Hideaki Sato, Ryokichi Shimpo 
    Abstract: Although zinc dialkyldithiophosphate (ZnDTP) is a commonly used lubricant additive for suppressing wear, its effectiveness has been reported to be insufficient when it was applied to sliding components made of aluminium (Al). This study proposes a novel surface modification process that enhances the antiwear performance of ZnDTP on Al sliding components. Fine particle peening (FPP) was performed to transfer shot particle elements onto a peened surface. Fe elements that were to react with ZnDTP, forming an antiwear tribofilm during sliding, were concentrated onto the Al peened surface through FPP using steel shot particles. Results of tribological tests performed on the peened surface revealed that Fe elements introduced through FPP can act as an adsorption site of ZnDTP and contribute to iron phosphate formation. The Fe-enriched surface fabricated through FPP exhibited reduced wear compared to the untreated surface when the ZnDTP-derived tribofilm successfully functioned.
    Keywords: peening; material transfer; ZnDTP; lubricant additives; tribofilm; tribology; friction coefficient; wear; surface texture; Al cast alloy.
