The effect of load on the friction and wear behavior of NBR and FPM was investigated using a ring-on-block tester under dry sliding. The hardness and morphology of worn surface were measured using Shore Hardness and stereo microscope, respectively. The results showed that at the load of 50, 100 and 150N, the wear loss of NBR was lower than that of FPM and the frictional coefficient of NBR was the same as that of FPM. While at the load of 175, 200 and 225N, the wear loss and frictional coefficient of NBR were higher than that of FPM. The reason for the variation of friction and wear behavior of NBR and FPM under different load was discussed preliminarily.

In the start stage of progressing cavity pump (PCP) and the well with high ratio of gas to oil, dry friction usually happens between metal rotor and rubber stator. Therefore, it is very important to investigate wear and frictional behavior of rubber with metal under dry sliding. In this paper, the effect of speed on the friction and wear behavior of three kinds of FKM/NBR blends (FKM, NBR, FKM/NBR=5:5) with the same Shore hardness was investigated using a ring-on-block tester under dry sliding. The morphology of worn surface was measured using stereo microscope. The results show that the queuing order of wear loss and coefficient of friction is NBR

The wear behavior of different plant abrasive to 45# steel was studied by using an abrasive rubber wheel tester. The worn surface of the frictional samples morphology was observed by using Scanning Electron Microscopy, and the wearing mechanism of different abrasive to 45# steel was analyzed. The results show that: on the experiment conditions, the wear loss from big to small is alfalfa abrasive, corn abrasive and wheat abrasive, and the wear rules of corn abrasive and wheat abrasive are similar, but the wear loss of alfalfa abrasive is much higher than the former two. The wear dominant mechanism of the wheat abrasive to 45# steel is mechanical polishing, the wear dominant mechanism of the corn abrasive to 45# steel is mechanical polishing and adhesive wear, the wear dominant mechanism of the alfalfa abrasive to 45#steel is micro-cutting and adhesive wear.

In this paper, the friction and wear behavior of FKM, NBR and FKM/NBR blends with the same Shore hardness was investigated in the MPV - 600 wear tester under water lubrication based on the actual working parameters of the screw pump. Wear mechanism of FKM/NBR blends with different load was also analyzed according to their wear loss and frictional coefficient. The results showed that the wear resistance of NBR was improved by the addition FKM. FKM/NBR blend with ratio of 2:8 owned the optimal wear resistance, which was close to that of FKM. The wear of FKM and FKM/NBR blend with ratio of 2:8 was controlled by fatigue wear, and the others were mainly controlled by abrasive wear.

In order to choose the rubber material and improve the service life of Progressing Cavity Pump (PCP ) when exploiting offshore crude oil, it is important to analyze friction and wear behaviour of stator and rotor of PCP in the mixture of crude oil with different water content. The friction and wear test about Nitrile -Butadiene Rubber (NBR) and Fluorine Rubber (FKM) were carried on ring-on-block tester, the wear loss was observed by electron microscope, the wear mechanism was also discussed. The results show that: (1) FKM owns better wearing resistance than NBR in the mixture of crude oil with different water content; (2) when the content of water in the mixture is less than 26%, the frictional coefficient of sample is 0.05, due to the oil film between the friction pairs; (3) when the content of water in the mixture is more than 26%, the frictional coefficient increases to 0.4, because of the water film between the friction pairs.

Micro Arc Oxidation

A relatively new process called microarc oxidation (MAO), also called plasma electrolytic oxidation (PEO), has emerged as a unique technique to produce hard, thick ceramic oxide coatings on different Mg or Al alloys. The magnesium offers various possibilities of application in industry, but its poor property in corrosion resistance, wear resistance, hardness and so on, limited its application. Through microarc oxidation, ceramic coating is directly formed on the surface of pure magnesium, by which its surface property is greatly improved. In this paper, a dense ceramic oxide ceramic coating was prepared on the magnesium by microarc oxidation in a Na2SiO3-Na2WO4-KOH-Na2EDTA electrolytic solution. The surface morphology of the coating was observed by the Scanning Electron Microscope (SEM). Using the X-ray diffraction (XRD), the phase structure of the coating was analyzed. The friction and wear behavior of the micro-arc oxidation ceramic coating under dry sliding against GCr15 steel was evaluated on a ball-on-disc test rig. The results showed that the magnesium was characterized by adhesion wear and scuffing under dry sliding against the steel, while the surface micro-arc oxidation ceramic coating experienced much abated adhesion wear and scuffing under the same testing condition. The micro-arc oxidation ceramic coating showed good friction-reducing and fair antiwear ability in dry sliding against the steel.
