Four material combinations of gears were tested: wheel and pinion uncoated, wheel and pinion coated, wheel coated and pinion uncoated as well as wheel uncoated and pinion coated.
For many engineering materials, further improvement of their properties through a modification of their microstructure, chemical composition, phase composition, and oil formulation is practically impossible [1].
The results from pitting tests obtained for gear material combinations with MoS2/Ti coating are summarised in Figs. 4 and 5.

Rotary viscometer for properties with continuous measurement of time variation of the materials, can be measured on the same materials at different shear rates, so it is widely used in the absolute measurement of viscosity of Newtonian fluid, and the apparent viscosity and rheological properties of non Newtonian liquid meter.
High temperature measurement of material viscosity, in order to prevent the chemical or physical reactions tested samples and the container between the contact surfaces, the non-contact measurement technology has become necessary.
You can believe that, along with the science and technology development and people more deeply on viscosity, viscosity measurement method will emerge, the measurement accuracy will be further improved, the measurement range will also further expand, these will be the organic heat carrier is more widely applied foundation.

Experimental Figure 1 shows the chemical structure of organic materials, the device structure of the OLEDs and schematic energy band diagram of devices.
The layer thickness of the deposited material was monitored using an oscillating quartz thickness monitor.
As mentioned earlier, at the doping level of DCJTB in DPVBi almost incomplete energy transfer occurs, so that we observe the emission from the host material, DPVBi itself.
