Composite coatings of PTFE/PEEK (Polytetrafluoroethylene/Polyetheretherketone) were prepared by electrostatic powder spraying method. The frictional coefficient were investigated by the orthogonal experimental method. The results show that 250°C preheating temperature and 150°C working temperature are better conditions for frictional coefficient.

Composite coatings of PTFE/PEEK (Polytetrafluoroethylene/Polyetheretherketone) were prepared by electrostatic powder spraying method. The factors were investigated on the preheating temperature and working temperature by the orthogonal experimental method. The results show that 250°C preheating temperature and 100°C working temperature are better conditions for playing good performance of PTFE/PEEK coatings.

The study aims to determine the effect of using a mixture of methanol add on to pertalite to the performance of gasoline engines, especially injection system with a capacity of 250 cc engine with two cylinders. This research used experimental method with variables used in this research is mixture of pure pertalite (P), mixture of pertalite - methanol 90% - 10% (PM1), mixture of pertalite - methanol 80% - 20% (PM2), mixture of pertalite - methanol 70% - 30% (PM3), mixed pertalite - methanol 60% - 40% (PM4), 50% - 50% (PM5) pertalite - methanol mixtures, pertalite - methanol 40% - 60% (PM6). Variable related in this research is power, torque and working temperature of the engine. The results of this study indicate that the addition of methanol with pertalite fuel tends to produce lower power and torque, while the temperature of the radiator and exhaust system shows that the use of methanol mixture with pertalite fuel can significantly increase the engine temperature of the vehicle.

Spraying Method

In order to improve the tribological performance of the physical vapor-deposited AlCrN coatings, molybdenum disulfide (MoS2)/poly tetra fluoroethylene (PTFE) coatings were fabricated on the AlCrN coatings surface through the thermal spraying method. The microstructure, adhesive strength, hardness, and tribological properties were investigated. Reciprocating sliding tests against SiC ball were executed with a ball-on-plate tribometer. Results showed that the adhesive strength between the AlCrN–MoS2/PTFE composite coatings and substrate was increased by about 15% compared with single AlCrN coatings. Compared with the single MoS2/PTFE coatings, the hardness of the AlCrN–MoS2/PTFE composite coatings surface was increased by about 15%. The MoS2/PTFE layer can availably reduce the friction coefficient of single AlCrN layer, and the AlCrN–MoS2/PTFE composite coatings exhibited the lowest and the most stable friction coefficient. In addition, the MoS2/PTFE layer existed on the wear track and accumulated on both the sides, which was the main reason that the friction coefficient was still lower compared with the samples without MoS2/PTFE coatings.
