Surface metallization of glass fiber(GF)/polyetheretherketone(PEEK)[GF/PEEK] is conducted by coating copper using electroplating and magnetron sputtering and the properties are determined by X-ray diffraction(XRD), scanning electron microscopy(SEM), and electron backscatter diffraction(EBSD).The coating bonding strength is assessed by pull-out tests and scribing in accordance with GB/T *** results show that the Cu coating with a thickness of 30 μm deposited on GF/PEEK by magnetron sputtering has lower roughness, finer grain size, higher crystallinity, as well as better macroscopic compressive stress,bonding strength, and electrical conductivity than the Cu coating deposited by electroplating.

The temperature and density of plasma jets were estimated with a Boltzmann plot and Stark broadening of Ar I(696.54 nm) lines by optical emission spectroscopy(OES) in the process of plasma plastic, and the morphology and microstructure of tungsten(W) powders were investigated by scanning electron microscope(SEM) and x-ray Diffraction(XRD), *** results show that the assumption of local thermodynamic equilibrium(LTE) was invalid at the end of the plasma jets, and earlier than this after the injection of tungsten powder. The temperature and electron density of the plasma jets were up to about T?=?6797 K with Qc?=?50 slpm and ne?=?1.05?×?1016 cm-3 with Qs?=?115 slpm at Z?=?60 mm, respectively, and both dropped rapidly with the injected tungsten powders of 20 μm. After the plasma plastic process,the spherical tungsten powders were prepared and there were some satellite particles on the surface of the spherical products. The tungsten powders were both composed of a single equilibrium α-W phase with a body centered cubic(bbc) crystal structure before and after plasma treatment.

Micro-arc oxidation （MAO）, a plasma electrolytic surface process, has attracted much interest as an effective technique to improve the wear resistance of aluminum alloys by creating a relatively thick and hard alumina coating on the component surface. However, previous studies of MAO aluminum alloys have shown that as-deposited and polished alumina coatings have a relatively high friction coefficient, for example, values of 0.6 and 0.7 against WC/Co and AISI 52100 counterfaces in dry sliding tests, respectively.

Absorbers and reflectors of electromagnetic waves have many applications, and so the interactions between electromagnetic waves and low-temperature plasma, particularly numerical analysis of reflection, absorption, and transmission of electromagnetic waves in unmagnetized, magnetized, nonuniform, and uniform plasma, have been a topic of intensive research. For instance, Laroussi numerically evaluated the interactions between electromagnetic waves and a uniform magnetized plasma cylinder, and Helaly and Yeh studied the scattering from nonuniform magnetized plasma cylinders.

Electromagnetic wave absorbing materials are being investigated as anti-electromagnetic interference coatings in self-concealing technology, and properties such as dielectric loss, conductive loss, and magnetic loss have been reported in the literature. These materials include metal oxides, alloy-epoxy composites, and especially metallic magnetic materials which have generated particular interest.

Titanium and its alloys are widely used in the aerospace, marine, and biomedical industry due to their unique bulk properties such as high strength-to-weight ratio and melting temperature, good corrosion resistance, and favorable biocom- patibility. However, in some applications, com- ponents made of titanium or titanium alloys exhibit poor wear resistance under stationary or dynamic loading as well as contact corrosion manifested by the relatively negative standard electrode potential （-1.63 V ） . In order to improve the surface properties of titanium and its alloys, several techniques such as PVD （ physical vapor deposition ） /CVD （chemical vapor deposition ） coatings,

Titanium oxides （TiO2） and TiO2 films have recently attracted more attention on the application of microelectronic devices and microwave communication systems for processing temperature and environmentally stable dielectric properties characterized by high relative dielectric constant and low dielectric loss. Many deposition methods have been used to prepare TiO2 films including pulsed laser deposition, filered arc deposition, sol-gel method and reactive sputtering methods. Previous reports on TiO2 films prepared by MDO have primarily focused on surface mechanical and biologic properties, in contrast.

1 Introduction Ion sources with wide energy and current ranges are used extensively in industrial applications such as ion implantation, etching, and deposition. Broad beam ion sources with a uniform current distributions are needed for many industrial applications and development of commercial ion bean technologies for surface modification of materials is impossible without highly efficient, simple, and dependable ion sources. These and other needs have spurred the development of high efficiency ion sources that can produce ion beams with high energy and current and require low or no maintenance.

Magnesium （Mg） and its alloys are one of the lightest metals used in the construction, automotive, aerospace, and communications industries. Owing to its low density, high specific strength, and good cast and welding ability, interests in Mg and Mg alloy are proliferating rapidly. However, there are some inherent problems arising from their chemically active nature, such as poor corrosion resistance, friction, and wear characteristicst21. In order to improve these properties,. surface modification is a viable approach and techniques such as electrochemical plating, anodizing, physical vapor deposition （PVD）, and chemical vapor deposition （CVD） have been proposed

Wear and corrosion are the main failure mechanisms of bearings and some measures have been proposed to prolong the working lifetime. Possible approaches include the use of more expensive materials, ion implantation, surface finish enhancement, and ion beam assisted deposition. Among them ion implantation is used extensively for the modification of surface and properties of materials and many studies have disclosed that the beating steel surface can be strengthened by ion implantation of different elements such as N, Mo, N and Mo, and so on.
