Based on actual working conditions and parameters of the hydraulic steering gear, the purpose is optimizing the rubber seal of steering gear by different rubbers mixing technology. Compare the five kinds of rubber with metal of the friction characteristics in dynamic fit, it can obtain a performance excellent rubber real in the specific operation conditions. And then improve the overall service life of the steering gear. It is first prepared the same hardness TPU and PVC and blends that the ratio is 3:7, 5:5and7:3 in this article. The pros and cons of the five rubbers are analyzed in friction and wear properties of the above experimental. The test curve of coefficient friction and wear with time has been done under different load at constant low speed. It determines TPU/PVC = 3:7 blends through friction and wear and wear mechanism of five rubbers with steel comparatively analyses, and the heat resistance and wear resistance of them are better than the other TPU/PVC blends and PVC under oil lubrication conditions.

AbstractDiamond-like carbon (DLC) and graphite-like carbon (GLC) coatings have good prospects for improving the surface properties of engine parts. However, further understanding is needed on the effect of working conditions on tribological behaviors. In this study, GLC and two types of DLC coatings were deposited on GCr15 substrate for investigation. The friction and wear properties of self-mated and steel-mated pairs were evaluated. Two temperatures (25 and 90 °C), three lubrication conditions (base oil, molybdenum dithiocarbamate (MoDTC)-containing oil, MoDTC+zinc dialkyldithiophosphate (ZDDP)-containing oil), and high Hertz contact stress (2.41 GPa) were applied in the experiments. The results showed that high temperature promoted the effect of ZDDP on steel-mated pairs, but increased wear under base oil lubrication. The increased wear for steel-mated pairs lubricated by MoDTC-containing oil was due to abrasive wear probably caused by MoO3 and β-FeMoO4. It was also found that in most cases, the tribological properties of self-mated pairs were better than those of steel-mated pairs.

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.

Mr Effect

The friction and wear properties of four different types of magneto-rheological (MR) elastomer were investigated. The MR elastomers have different matrix materials and structures. Most MR elastomers have a silicone matrix, since it has a more significant MR effect under a magnetic field compared to other materials. The mechanical properties of silicone, however, are poor compared to other materials, so it is difficult to use them in engineering applications. Therefore, a new polyurethane matrix material was used to enhance the friction and wear properties of MR elastomer. Additionally, two different matrix materials (silicone and polyurethane) were synthesized, and MR elastomers were structurally combined to improve the friction and wear performance. The friction characteristics of each MR elastomer were evaluated under reciprocating operating conditions. Wear depth was also measured to estimate the wear resistance. The test results show that the friction and wear performance of the modified MR elastomers are enhanced compared with the silicone-based MR elastomer.
