Introduction Along with the development of science and technology, especially the extension of electromagnetic technology application, more and more friction pairs of electrical equipments and appliances have been used under the electromagnetic condition, and most of the materials used are ferri-magnetic and therefore the study on the influential factors and regularity of friction and wear characteristics of ferri-magnetic friction pairs under a magnetic field condition and the establishment of theoretical basis and guideline for concurrent tribology have become critical topics for mechanical designs.

With the increasing number of laser pulses, more material is vaporized from the sample and the depth of grooves keeps increasing.
So only the material about the interfering minima position is remained at its original position after ablation as show in Fig. 5b.

The materials used to laser transmission micro- joining based on the mask are PET, and the experiments are conducted on diode laser.
Therefore, the materials can’t absorb enough heat.
However, when clamp pressure is more than 1.5MPa, materials are squeezed because of oversize clamp pressure, preventing the molten of materials.

Reflective properties Materials selected By film theoretical knowledge, in order to achieve high reflectance and higher laser damage threshold: (1) Generally, the materials with big difference in reflectance are chosen to decrease the number of the films and reduce production cost and preparation difficulty.(2)From the perspective of laser destruction to the films, membrane material should have high laser damage threshold.
High and low refractive index materials are deposited alternately in the depth of λ0/4, which constitutes the dielectric medium HR film system[4].
The film system Si/(LH)110(LH)24/Air is designed on ultra-smooth silicon substrate, with Si and SiO2 as high and low refractive index materials, by use of TFCALC3.4 film design software.

Initially, the average co-ordination number and porosity of assembly retained a constant during the simulation testing but after reaching the so-called ‘phase transformation’ point, in which during loading phase, negative pore water pressure developed due to dilating tendency of the material followed by subsequent positive pore pressure build-up, the average co-ordination number of assembly fluctuate and decrease in cyclic tune with the loading cycles, however, the porosity of assembly fluctuate and increase in cyclic tune with the loading cycles.

There are materials, however, which, due to their heat sensitivity cannot be processed by melt methods, and from these composites can be prepared by some kind of dry blending process [6].
Therefore the traditional dry blending machines cannot be used for mixing these materials, but a new method, ball milling, can meet, however, the expected requirements.
Materials and methods GUR 4120 of Ticona ultra high molecular weight polyethylene (UHMWPE) was used as a matrix material, to which multiwalled carbon nanotubers (MWCNT) produced by the Pannon University of Veszprém, Hungary were added at 0.25, 0.5 and 1 wt% loading (see Figure 1.).
