Lubricating Properties

1Cr13MoS is a kind of material with excellent corrosion resistance and good mechanical properties. Meanwhile, it also has good self-lubricating properties due to the presence of molybdenum disulfide phase inside the material and can be used as friction pair material in the pump. In this paper, the hardness, microstructure, distribution of the self-lubricating phase, friction and wear properties of 1Cr13MoS after heat treatment were studied. After quenching at 1000 °C and tempering at 520 °C, the hardness of 1Cr13MoS prepared by pyrometallurgy is higher than that of HB 350. The tempering sorbite structure is evenly distributed, and the self-lubricating phase MoS2 is discretely distributed on the substrate with the average size is about 6 μm, which leads to good friction and wear properties. It is worth noting that the 1Cr13MoS is actually operated as friction pair material on the water pump and has a significant wear improvement effect compared to the conventional 12% chrome steel series.

Ti (C,N)/ZrO2/WC nanocomposite cermet die materials were fabricated by vacuum hot pressing process, the materials have better comprehensive mechanical properties. The friction and wear properties of Ti (C,N)-based nanocomposite cermet die materials were studied, and the worn surfaces microstructure were observed and analysed by SEM and XRD. The experimental results showed that when the rotate speed was higher, the coefficient of friction of the developed cermet die material, which is 0.3-0.4, was lower than that without the addition of nanoZrO2 and micrometer WC. The main wear mechanisms were abrasive wear, oxidation wear and adhesive wear.

Taking into account the condition that dry friction may occur when Si3N4 and SiC are self-made into friction pair, experiments are carried out to contrast the friction and wear properties under the condition of dry friction. In this experiment SiC friction pair presents better friction and wear properties, whose ultimate bearing capacity is better than Si3N4.

Main Factor

The friction and wear properties of several common metal materials (45#, 25CrMn, and 40CrNiMo) friction pair under oil lubrication was investigated on M-200 Type wear tester, and studied the friction under the condition of differ sliding speed and pressure. The results show that: the 25CrMn/45# steel pair has better tribological and wear performance; the load is the main factor which influences the friction of the material at the low sliding speed; the main wear form is adhesive wear, but the wear mechanism is gradually became from adhesive wear to abrasive wear and flaking wear with the contact pressure and sliding speed increased.

Friction And Wear Properties

Friction and wear processes of AgCuX ( G , CF and AlN ) composites- CuAgV alloy friction pair and effects of different additive content in silver based composite on friction and wear behavior are studied in this paper. The microstructure of the brush wear surface is observed by SEM. The results show that when graphite content is up to 9 wt.%, Ag - Cu - CF - G composite exhibits the best wear properties; when the content of aluminum nitride is up to 0.5 wt.%, Ag - Cu - AlN - G composites has the most comprehensive performance. The wear loss of both composites arises with the increase of both pressure and speed, but when speed reaches a critical value, the increased amplitude of wear loss tends to be steady.

Friction And Wear Properties

Friction and wear properties of the Ni-M-S alloy system were examined by changing the composition of M (Mo, Nb or Fe) and S, respectively. Sulfides or complex sulfides such as MoSx or FeNbxSy formed during rubbing or annealing were found to be good materials as a friction modifier, and they were discussed relative to the transformation of non-stoichiometric into stoichiometric compound during abrading. The effect of adding Fe to the matrix was also investigated with the system, and it was found that the Fe especially improves the wear property, among others.

Friction And Wear Properties

To study the friction and wear properties of S136/WC-Co friction pair, friction and wear tests in air jet, nitrogen jet and nitrogen cold plasma jet atmospheres are carried out. The morphology and composition of friction surface are analyzed by camera, scanning electron microscope and energy-dispersive X-ray spectroscope. The wear behaviors and mechanism of anti-wear of the three jets to S136 are also discussed. The experiment results prove that the reactive species in the nitrogen plasma jet contribute to the generation of oxidation film on the friction surface quickly to reduce the wear of S136/WC-Co friction pair in real-time.
