The friction brake works as an indispensable guarantee for regular work and safety operation of vehicles and industrial equipments. Friction and wear behaviors of brake's friction materials are considered as an important subject. In this article, friction materials were classified by matrix categories, and their major components were introduced first. Then, the advantages and disadvantages of each friction material were summarized and analyzed. Furthermore, the microcontacting behaviors on friction interface and the formation mechanism of various friction films were discussed. Finally, the influential rules and mechanism of braking conditions (temperature, pressure, and velocity) on the friction and wear behaviors of friction materials were summarized. It is concluded that the friction film, an intermediate product in braking, is greatly beneficial to protect friction materials from being seriously abraded. The braking conditions have complicated influences on friction and wear behaviors of brake. Generally, the friction coefficient tends to be fairly low while the wear rate increases rapidly under a condition with high temperature, braking pressure, or initial braking speed.

“…Carbon-carbon composites represent yet another class of materials that has been used predominantly for aircraft and motor racing applications, but their inherently high cost and poor braking performance at low temperatures limits their application area [16]. Although not included in Table 1, CMCs such as carbon-fiber reinforced silicon carbide (C/SiC) composites are known to possess excellent thermal stability up to 1300 • C, superior tribological properties over GCI along with significant weight savings but suffer from very high costs and are consequently notably used only in high performance racing cars and luxury vehicles [17][18][19].

Gray cast iron (GCI) is a popular automotive brake disc material by virtue of its high melting point as well as excellent heat storage and damping capability. GCI is also attractive because of its good castability and machinability, combined with its cost-effectiveness. Although several lightweight alloys have been explored as alternatives in an attempt to achieve weight reduction, their widespread use has been limited by low melting point and high inherent costs. Therefore, GCI is still the preferred material for brake discs due to its robust performance. However, poor corrosion resistance and excessive wear of brake disc material during service continue to be areas of concern, with the latter leading to brake emissions in the form of dust and particulate matter that have adverse effects on human health. With the exhaust emission norms becoming increasingly stringent, it is important to address the problem of brake disc wear without compromising the braking performance of the material. Surface treatment of GCI brake discs in the form of a suitable coating represents a promising solution to this problem. This paper reviews the different coating technologies and materials that have been traditionally used and examines the prospects of some emergent thermal spray technologies, along with the industrial implications of adopting them for brake disc applications.

“…High pressure torsion (HPT), 3) equal channeling angular pressing (ECAP) 4,5) and accumulative roll bonding (ARB) 6) are such bulk-SPD processes. Mechanical milling (MM) and alloying (MA) [7][8][9][10][11][12][13][14][15][16] are SPD-powder metallurgy (PM) processes. Most of those bulk-SPD processes have an advantage that the materials retain almost the same shape after processing, whereas the SPD-PM process can be easily transferred to the conventional PM process, which has been applied for hundreds of years.…”

New Microstructure Design for Commercially Pure Titanium with Outstanding Mechanical Properties by Mechanical Milling and Hot Roll Sintering

Commercially pure titanium powder is subjected to mechanical milling (MM)-a severe plastic deformation process-for various periods of time. The MM powder has two different kinds of microstructure, which can be controlled by the MM conditions. They include ultra fine and coarse grain structures known as ''shell'' and ''core'', respectively. Subsequently, these MM powder is sintered using a hot roll sintering (HRS) process. The HRS materials with the shell and the core have a network structure of continuously connected shells, which is known as a harmonic structure. The HRS materials with the harmonic structure simultaneously demonstrate both high strength and elongation. These outstanding mechanical properties are influenced by the harmonic structure characteristics such as shell and core grain sizes, and shell fraction and shell network size. Thus, the harmonic structure can be considered as a remarkable design for improving the mechanical properties of commercially pure titanium as well as other metallic materials.
