Porous Mullite

Mullite reinforced composites were produced by the injection molding technique to develop environmentally friendly friction materials for automotive applications. In order to examine the effect of mullite content on the friction and wear properties, two different specimens containing 10wt% and 30wt% of mullite were respectively fabricated and wear-tested by using the plate-on-disc type sliding friction and wear test machine. The sliding friction and wear test demonstrated that both specimens show similar tendencies at different sliding speeds under a low load of 2.9N. In comparison with common glass fiber reinforced composites, both of the mullite reinforced composites exhibited a lower wear rate at room temperature.

Friction And Wear Properties

Plate-on-disc type sliding friction and wear test was conducted to investigate the friction and wear properties of mullite reinforced composite (M composite), and compared with glass fiber reinforced composite (GF composite). The friction and wear test revealed that M composite has good wear resistance under mild sliding conditions, but the wear rate gradually increases under severe sliding conditions. M composite exhibited higher friction coefficient than GF composite at room temperature and maintained the friction coefficient stably at higher temperatures. The composite film formed on counter material against M composite showed influences on the friction and wear properties under severe sliding conditions.

Friction and wear are very important in mechanical design. This paper studies the friction and wear characteristics of 45 steel under oil lubrication. The sliding friction and wear experiment was carried out with the pin plate friction pairs on the MMW-1A friction and wear test machine. Researching the influence of velocity on friction factor under the same load, the relation between wear and load and wear analysis under the same speed different loads. The results showed that under the same load and with the increase of velocity, the friction factor had a gradually decreasing trend. When some of the parameters were certain, the wear volume and the loading force was roughly linear relation. Pitting occurred when the load increased.

To study the effects of different oral environment factors on the friction and wear properties between dental prosthetic materials and natural teeth, several comparing experiments were implemented by using a reciprocating friction and wear test machine containing an artificial saliva solution. Three kinds of factors including load, frequency and cycles were investigated on titanium alloy TC4 and zirconia ceramic. The experimental results showed that zirconia ceramic has a better wear resistance and a lower friction. The wear loss of titanium alloy TC4 was 10 times of that of zirconia ceramic under same conditions. A significant positive correlation between three factors and wear loss was also discovered.

The Impact

In this paper, phenolic resin-based composite materials were prepared using glass fiber instead of asbestos for the oil driller brake friction materials, and its impact performance and friction and wear properties were investigated, and compared with performance of asbestos containing material. The results showed that the impact strength of glass fiber reinforced material were higher than that of asbestos reinforced material. When the friction speeds were constant, the friction coefficient of asbestos reinforced material changed in the range of 0.308~0.4302, and the glass fiber reinforced material was 0.308~0.425.The glass fiber can replace asbestos as a reinforced material for oil driller brake friction materials.

Purpose The purpose of this study is to investigate the effect of iron content on the friction and wear performances of Cu–Fe-based friction materials under dry sliding friction and wear test condition. Design/methodology/approach Cu–Fe-based friction materials with different iron content were prepared by powder metallurgy route. The tribological properties of Cu–Fe-based friction materials against GCr15 steel balls were studied at different applied loads and sliding speeds. Meanwhile, microstructure and phases of Cu–Fe-based friction materials were investigated. Findings Cu–Fe-based friction materials with different iron content are suitable for specific applied load and sliding speed, respectively. Low iron content Cu–Fe-based friction material is suitable for a high load 60 N and low sliding speed 70 mm/min and high iron content Cu–Fe-based friction material will be more suitable for a high load 60 N and high sliding speed 150 mm/min. The abrasive wear is the main wear mechanism for two kinds of Cu–Fe-based friction materials. Originality/value The friction and wear properties of Cu–Fe-based friction materials with different iron content were determined at different applied loads and sliding speeds, providing a direction and theoretical basis for the future development of Cu–Fe-based friction materials.

Friction And Wear Properties

The present paper report the results of an experimental investigation of the temperature effect on the sliding friction and wear properties of the bulk metallic glass (BMG). To improve the friction and wear properties of the BMG, the disk specimens were developed in the alloy system of Fe 67.6 C 7.1 Si 3.3 B 5.5 P 8.7 Cr 2.3 Mo 2.6 Al 2 Co 1.0 using hot metal and industrial ferro-alloys. The friction and wear test was performed using flat-on-flat contact configuration of unidirectional tribometer and Si 3 N 4 ceramic disk used as a counterpart. The worn surfaces of the BMG were observed by using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS). The results indicated that the friction and wear properties of the BMG depend on the glass transition and the formation of protective oxide film. The friction coefficient decreased with increasing temperature, while it increased slightly when the temperature passed the glass transition temperature (Tg). The worn specimens were exposed to abrasion, adhesion, oxidation and plastic deformation. In addition, obvious surface flow characteristics was accompany during wear test.

Friction And Wear Tests

The effects of hydrogen on friction and wear properties of Ti–6Al–4V alloy sliding against GCr15 steel were investigated through dry sliding friction and wear tests in atmosphere at room temperature. Wear mechanism was determined by studying the morphology and chemical element of worn surface using SEM and EDS. Results show that friction coefficient decreases slightly and wear rate increases after hydrogenation. Wear mechanism is discussed.
