...A. Abouel-Kasem; A. Ezz El-Deen; K. M. Emara; S. M. Ahmed Cavitation erosion pits and their effects on erosion progression were investigated in detail for SUS 304 stainless steel, α + β brass (60/40), and pure aluminum (Al-99.999 and Al-99.92) by means of vibratory erosion. Two kinds of erosion...

... only on the interface behavior, specifically its stiffness. In this study, ultrasound was used to investigate the increase in interfacial stiffness with time. A power law relationship between stiffness and hold time was observed for both steel and aluminum surfaces pressed together. An analytical model...

... on the proposed lubricant performance, pin-on-disk experiments were conducted with spherical copper pins (radius 6.5 mm ) and aluminum disks ( Ra = 1.35 μ m ) . Friction coefficient measurements were taken at more than 20 distinct operating conditions while varying the lubrication condition (unlubricated, boric...

...A. Abouel-Kasem; S. M. Ahmed The mechanism of cavitation erosion is investigated in detail through observations of the removed particles from pure aluminum (Al-99.999). The particles removed during the incubation stage have distinctive characteristics compared to those removed in the subsequent...

... steel sheets and aluminum sheets, as a function of applied normal load. Models are obtained from serial, parallel, or closed-loop association structures for linear transfer functions. Numerical values of delays, time constants, and gain are identified for each test order; complexities and structures...

... pressures, stress contours and deformed profiles of different cylinder sizes and applied loads are illustrated and discussed. The results are compared to published solutions, and good agreements are observed. aluminium copper iron adhesion adhesives finite element analysis Galerkin method...

...Masaya Kurokawa; Yoshitaka Uchiyama; Tomoaki Iwai; Susumu Nagai Tribological properties of several kinds of polyoxymethylene (POM) composites were evaluated for the purpose of developing a polymeric tribomaterial especially suited for mating with aluminum parts having low surface hardness. POM...

...Kwangjin Lee; Frank W. Brooks,, Jr. Hot spotting and judder phenomena were observed in automotive aluminum drum brakes. A vehicle judder test schedule was developed to determine the critical speed for thermoelastic instability (TEI). The brake material properties relevant to the TEI analysis were...

...M. R. Lovell; Zhi Deng; M. M. Khonsari A pin-on-disk tribometer was used to investigate the influence of several parameters on the sliding friction coefficient between hard and deformable surfaces. Pin (1045 tool steel) and disk (aluminum 1100) were utilized to simulate the interaction of a harder...

... the surface structure specimens of low-carbon steel, aluminum and copper were subjected to wear tests and then investigated by X-ray. Under certain test conditions it was found that the changes in the surface layer structure, evidenced by the structural broadening of diffraction lines, reach a maximum level...
