It is well known that AlN still maintains stable in the high temperature conditions. This is quite attracted for the electrical engineering. Moreover, the heat conduction of AlN is several times efficacious than the other ceramics. Hence, it is widely used for the heat dissipation. The green technology of composite with PCM is always worked as a constant temperature cooler. Therefore, PCM has been...
The wreckage of mechanical elements caused by the wear has been thought as an important problem for the mechanical engineers. Hence, it is necessary to improve the material properties of mechanical elements for the purpose of wear resistance. Moreover, low friction always plays an important role for saving energy. The technologies of materials science and surface engineering have been used widely...
The surface voltages of tribo-electrification for the typical four polymer pairs of POM/POM, POM/PE, POM/PA, and POM/PP were investigated in this study. The vertical rotation friction tester was used to conduct the experiment in the dry and severe wear condition. By the experimental results, the relationships between frictional characteristics and trib-electrification are clarified. Moreover, the...
The traditional method of using the continuous variation of the friction coefficient with sliding distance to monitor the tribological properties between the contacts of soft metal films is generally low in sensitivity. This paper proposed the novel method of using instead the continuous variation of tribo-electrification voltage. This method was investigated experimentally for the dry friction sliding...
