Simultaneously, the workpiece is rotating by a geared motor, so the material of the wire piles up a line on the surface of the workpiece.
When the Wire feed head moves to the next place after a whole circle, the piled material circles will form a thin layer on the workpiece.
The welding layer is formed by overlapping tracks, and every track has a rough surface formed by the uneven flow of melted material.

NiO is an attractive material for wide range of applications, such as electrochromic display devices [3], p-type transparent conductive films [4], anti-ferromagnetic materials [5], etc, because its good optical and electrical properties and chemical stability.
When the Au contents are below 9.6 at.%, the NiO-Au composite films show p-type conduction, but they display n-type conduction as Au contents are increased to above 13.3 at.% Acknowledgements This work was supported by the National Science Council and Ministry of Economic Affairs of Taiwan through Grant No. 97-2221-E-131-004 and 98-EC-17-A-08-S1-006, respectively.

The Barkhausen effect in ferromagnetic materials as a typical example provides a good way to study the dynamical universality of complex disorders [1-6].
In the traditional Barkhausen noise experiment, the magnetization dynamics are detected by a coil wound around the magnetic material.

Study on the preparation and property of the ceramic film on the LY12 aluminium alloy Xiaowen Chen a, Defen Zhang b* School of Materilas Science and Engineering Southwest Petroleum Univerisity, Chengdu City, Sichuan Province 610500 a xwchen5188@163.com; b zhangdefen0304@163.com (* corroesponding author) Keywords: LY12 aluminum alloy; Microarc oxidation; Corrosion resistance Abstract: The ceramic thin film on the surface of LY12 aluminum alloy were prepared by the method of the microarc oxidation.
Experimental materials and procedure LY12 aluminum alloys were used, four piece of cuboid aluminum alloys with the 20mm×30 mm ×1.8mm by wire-electrode cutting, the chemical element is listed as table 1[8] .Microarc oxidation equipment includes power supply, sitting press control system, eletrolytic trough, stir system and circulated system.
It can obviously be seen from the table 4 that the thickness of the aluminum alloy by microarc oxidation is larger than that of base materials and the hardness of film is increased with the increase of current density which is related to the increased thickness with the increase of current density current.
But with the continue increase of the current density, ceramic film was breakdown, which not only result in roughness, porosity and large particles, but also make the ceramic material peel off and separate from the sample surface under the high voltage and large current, thereby it lead to density of ceramic film and tightness decreased, finally result in corrosion resistance of microarc oxidation film prepared under high current density is lowered.

This deposition technique produces the microstructure characterized by both flat particles called splat, and micro defects involving globular pores and intrasplat cracks, which allow an inelastic deformation of this brittle material.
The material properties assigned to the BC were those of the CoNiCrAlY alloy generally used in GT blades.
The material of the substrate (SUB) was assumed to be a Ni-based super alloy IN738LC.
The dependency of the loading pattern on stress was caused by the brittle-ductile transition temperature of the bond coating material.

Coal gangue hill's surface weathered material is coarse and have a poor porosity .The soil has a bad water supply capacity and water retention capability[7].
At present coal gangue utilization technology has been widely used in building materials preparation, power generation, chemical utilization, landfill, Which have obtained good environment economic benefits.The main technologies include coal gangue brick technology, coal gangue system cement technology, coal gangue extraction chemical raw materials technology, coal gangue system ceramic technology, coal gangue power generation technology, coal gangue paving and backfill technology, etc.Because the comprehensive utilization of coal gangue technology development is difficult, expend cost is high, the coal gangue technology research and development progress is slow, the technology currently can not meet the needs of sustainable development, more advanced technology research and development is still needed[10]. 3 Peroration The governance and management of coal gangue could ease the orefield ecological environment destruction pressure, promote the economic and the regional sustainable

Magnetite nanoparticles have been successfully prepared by hydrothermal method from FeCl3 as starting material.
Introduction Magnetite nanoparticle (Fe3O4) is one of magnetic materials which attract much attention due to its unique properties such as superparamagnetic, high biocompatibility and low toxicity [1].
The value of saturation magnetization indicates the magnetizing power of a material.
