  • Wear behavior of silicone rubber/carbon black coatings on 6061 aluminum alloy surfaces
    Progress in Organic Coatings, 2020
    Co-Authors: Masoud Barekat, Reza Shoja Razavi, Saeed Bastani
    Abstract:

    Abstract In this paper, the effects of structural and process variables on wear resistance of silicone rubber/carbon black coatings on 6061 aluminum alloy surfaces are studied. Testing parameters have been optimized for maximum wear resistance based on taguchi orthogonal design with six important parameters, viz. polydimethylsiloxane (PDMS) molecular weight, oxime/OH ratio, catalyst weight percent, pigment weight percent, surface preparation method and Adhesion Promoter type. The analysis of variance showed that the wear resistance strongly depends on oxime/OH ratio and catalyst weight percent. PDMS molecular weight and pigment weight percent also have intermediate effects. Neither the surface preparation method nor Adhesion Promoter type had any effects on wear resistance in this study. The optimum sample was prepared according to the best levels of each factor and the wear resistance in optimum conditions was reasonably in agreement with the experimental data. Scanning electron microscopy analysis of wear surface and debris showed two mechanisms: cohesive wear with fatigue mechanism and interfacial wear with Adhesion mechanism.

  • wood polyethylene composites using ethylene vinyl alcohol copolymer as Adhesion Promoter
    Bioresource Technology, 2006
    Co-Authors: Taeho Yoon, Jongmoon Rhee
    Abstract:

    Abstract Saw dust–reinforced linear low density polyethylene (LLDPE) (1:1) composites were prepared by using ethylene–vinyl alcohol copolymer (EVAL) as Adhesion Promoter to improve mechanical strength. To evaluate the optimum vinylalcohol (VA) content in EVAL, various EVAL samples containing different contents of VA were used. The tensile properties of saw dust–LLDPE composites were improved by using EVAL as Adhesion Promoter in place of ethylene–vinyl acetate copolymer (EVAc). The saw dust–LLDPE composites prepared with EVAL containing 15 mol% VA showed the maximum yield stress and modulus. The tensile stress increased with addition of EVAL up to 3 wt% on the wood filler, and then leveled off in the range of 3–10 wt%. However, the elongation was decreased with increasing VA content. Hydrogen bonding interaction between saw dust and EVAL was detected by FT-IR spectra. When EVAL consisting with 15 mol% VA was used, good Adhesion between saw dust and LLDPE matrix was confirmed by SEM fractography.

  • the Study of Polyimide Films and Adhesion Using a Surface Acoustic-Wave Sensor
    Sensor Actuat B-Chem, 1991
    Co-Authors: D W Galipeau, R Lec, John F. Vetelino, Clément Feger
    Abstract:

    A dual delay line surface acoustic wave (SAW) sensor on an ST-quartz substrate has been used to study water uptake and downtake and its effect on Adhesion in both cured and uncured polyimide films. Film samples both with and without Adhesion Promoter have been studied. The experimental results suggest the possibility of using a SAW sensor as a cure indicator, humidity sensor or Adhesion sensor.

  • The study of polyimide films and Adhesion using a surface acoustic wave sensor
    IEEE Symposium on Ultrasonics, 1990
    Co-Authors: D W Galipeau, Clément Feger, John F. Vetelino
    Abstract:

    A dual delay line surface acoustic wave (SAW) sensor on an ST-quartz substrate has been used to study water uptake and downtake and its effect on Adhesion in both cured and uncured polyimide films. Particular attention is focused on the effect that an Adhesion Promoter may have on the strength of the adhesive bond. Film samples both with and without an Adhesion Promoter were studied. The experimental results suggest the possibility of using a SAW sensor as a cure indicator, humidity sensor, or Adhesion sensor.
