“…In addition to the macro-size tribology (various mechanical devices, the crustal movement (earthquake), et cetera), microtribology and nanotribology are also appearing such as the micromotors and micromachines in integrated electric control system. Many studies point out that the mechanical properties of materials have a size effect [9], and the tribological properties of the materials are also the same [2,[10][11][12][13][14][15][16][17][18]. In 2011, Orlova [16] directly improved the friction and wear performance of the 18-100 type truck bogie by changing the size and shape of the friction wedge.…”

“…In the study of the effect of magnetic field on the dry sliding tribological properties of metal materials [18], the size effect [9] of the tribological properties of the materials is noticed. Figure 1 shows the effect of magnetic field intensity on the line-wear-rate of CuZn pins and rings.…”

“…And their corresponding diameters of cross sections are 0.6 and 4.0 mm, respectively. The chemical composition of CuZn [18] pins are shown in Table 2. Each friction testing last for 1 h. After each friction testings, the specimen pins are cleaned by anhydrous ethanol, then dried.…”

“…1. Line-wear-rate of CuZn pins and rings under the influence of magnetic field intensity [18]. The difference of contact area of the friction couple may directly affect the actual contact stress (P a ) of the friction pairs, the distribution of the local force and the amount of elastic deformation caused by a positive pressure, the transmission efficiency of frictional heat and the vibration caused by friction sliding, et cetera.…”

The tribological tests are carried out to assess the effect of pin diameters on wear characteristics via changing contact stresses and sliding speeds to provide support for choosing friction pair sizes. The friction couple is set as CuZn pins for medium carbon steel (No. 1045 steel) rings. The differential wear rate and its calculation formula are defined to express the line wear rate or the wear resistance of unit cross-section area. The effect of the pin end surface diameter on differential wear rate and its scale/increased multiplier are investigated. When the product (P V ´=0.095) is kept constant, the abrasion loss for the specimens of a small diameter (d 1 = 0.6 mm) is lesser than that of the specimens of a large diameter (d 2 = 4.0 mm). As compared to the sliding speed, the change in contact stresses exerts a greater influence on the wear behavior, especially for small-diameter specimens. The differential wear rate of small-diameter specimens is always higher than that of the specimens of a large diameter. The scale multiplier of the differential wear rate is always larger than that of the contact pressure stress, especially for small-diameter specimens.

Magnetic-field tribological behaviors of aluminum-alloy and steel

et al. 2018

View full text Add to dashboard Cite

This paper used aluminum-alloy-2A02 (paramagnetic) and High-Speed-Steel (HSS) W18Cr4V (ferromagnetic) as the research objects to study the effect of DC magnetic-field on the dry tribology performance adopting the mutual matching methods (aluminum-alloy pin to HSS ring and HSS pin to aluminum-alloy to HSS ring, respectively). The wear rate of aluminum-alloy ring coupled with HSS pin was larger than that of pin coupled with HSS ring, which indicated that the influence of contacted surface size and hardness of friction pairs should be considered in the tribological research and application. The material of high magnetic permeability led to the wear rate decreases under a magnetic-field. The mechanism of sliding wear namely the ferromagnetic debris is adsorbed by HSS surface under the magnetic force. The wear rate is affected by the magnetic force depending on pin/disc material in a magnetic-field. The friction coefficient of aluminum-alloy pin/HSS ring is larger than that of HSS pin/aluminum-alloy ring, indicating the high difference of magnetic permeability for the coupled materials is disadvantageous to the antifriction effect of magnetic-field.
