Applicability of Stress Singularity Parameter for Evaluating Adhesive Strength of Coating Film (Phase 2). Adhesive Strength Evaluation of Coating Layer by Modified Pin Test.
Quarterly Journal of The Japan Welding Society, 1991Co-Authors: Akio Izuwa, Masahiro Nitta, Yoshiaki Inoue, Mosao Toyoda, Mitsuo TsukamotoAbstract:To establish the Adhesive Strength evaluation method of thin coating layer with high Adhesive Strength, hard chrominum plating and (Al2O3+TiO2) spray coating were tested by newly proposed pin test method and their date were evaluated by stress singularity parameter (kcr).

Applicability of stress singularity parameter for evaluating Adhesive Strength of coating film. (Phase 1). Adhesive Strength evaluation of plasma sprayed coatings by tesile pin test.
Quarterly Journal of The Japan Welding Society, 1991Co-Authors: Yoshiaki Inoue, Akira Noutomi, Akio Izuha, Masao Toyoda, Mitsuo TsukamotoAbstract:Selecting the tensile pin test from among the test procedures for evaluating the Adhesive Strength of sprayed coatings, the authors devised an Adhesive Strength evaluation technique.The results obtained are summarized as follows;1) The fracture net stress (σnet)cr obtained by the pin test is influenced by the coating thickness and pin diameter, and thus dose not necessarily use as an index of the Adhesive Strength.2) In the vicinity of the coating edge of the pin test, the stress σy in load direction is inversely proportional to the square root of the distance x from the coating edge to the center of pin.This stress singularity is expressed as follows; σy= κ/√x = FI×σnet/√x in which κ is an index representing the size of the field of singular stress.3) The pin test results, when sorted out using the stress singularity parameter kcr universal values were given regardless of changes in coating thickness and pin diameter, suggesting that employing kcr enables the Adhesive Strength to be quantitatively evaluated.

The Adhesive Strength and initial viscosity of denture Adhesives
Acta Odontologica Scandinavica, 2014Co-Authors: Guang Hong, Maimaitishawuti Dilinuer, Gang Zheng, Xinzhi Wang, Keiichi SasakiAbstract:Abstract Objective. To examine the initial viscosity and Adhesive Strength of modern denture Adhesives in vitro. Materials and methods. Three cream-type denture Adhesives (Poligrip S, Corect Cream, Liodent Cream; PGS, CRC, LDC) and three powder-type denture Adhesives (Poligrip Powder, New Faston, Zanfton; PGP, FSN, ZFN) were used in this study. The initial viscosity was measured using a controlled-stress rheometer. The Adhesive Strength was measured according to ISO-10873 recommended procedures. All data were analyzed independently by one-way analysis of variance combined with a Student-Newman-Keuls multiple comparison test at a 5% level of significance. Results. The initial viscosity of all the cream-type denture Adhesives was lower than the powder-type Adhesives. Before immersion in water, all the powder-type Adhesives exhibited higher Adhesive Strength than the cream-type Adhesives. However, the Adhesive Strength of cream-type denture Adhesives increased significantly and exceeded the powder-type dentu…

Influence of composition on the Adhesive Strength and initial viscosity of denture Adhesives
Dental Materials Journal, 2014Co-Authors: Guang Hong, Kentaro Hayashida, Takeshi Maeda, Hiroshi Murata, Keiichi SasakiAbstract:To investigate the effect of composition on the initial viscosity and Adhesive Strength between denture Adhesives and the denture base. Two types of water-soluble polymers (methoxy ethylene maleic anhydride copolymer [PVM-MA] and sodium carboxymethyl cellulose [CMC]) were used. Samples were divided into three groups. Group 1 contained only PVM-MA; Group 2 contained only CMC; and Group 3 contained PVM-MA and CMC. The initial viscosity and Adhesive Strength were measured. For Group 1, the initial viscosity increased significantly as PVM-MA content increased. The Adhesive Strength of Group 1 lasted longer than Group 2. The Adhesive Strength of Group 3 varied greatly. The ratio of CMC and PVM-MA has a significant effect on the initial viscosity and Adhesive Strength of denture Adhesives. Our results suggest that it is possible to improve the durability of a denture Adhesive by combining different water-soluble polymers.
