溅射

Nickel chromium alloy was cheaper than nickel, and its sputtering aggradation velocity was more than that of nickel, so the immediacy costs of sputtering nickel chromium alloy electrode was less than that of sputtering nickel electrode.

镍铬合金价格低于镍金属，溅射沉积速率也比镍金属要快，所以溅射镍铬电极的直接成本低于溅射镍电极。

Investigation was made of the sputtering rate in glow discharge lamp with re-lation to constituent of 25 different specimens of 6 binary systems, namely, Cr-Fe, Bi-Sb,Cu-Zn, Ag-Cu, Al-Zn and Cd-Sn, by measuring mass loss after each sputtering under con-stant Ar pressure and voltage applied. The correlation, in general, between sputtering rate andconcentration of constituent of these non-intermetallic binary alloys obeys the hyperbolic lawunder steady state, yet may be approximately regarded as linear only on certain special condi-tion if the two components of the alloys with similar sputtering rates.

在恒定气压和电压条件下，用测量溅射减量的方法，系统研究了Cr—Fe，Bi-Sb，Cu—Zn，Ag—Cu，Al-Zn和Cd—Sn六个系统的25个试样在辉光放电灯中溅射率与组分的关系结果表明；阴极溅射在稳态时，二元合金的溅射率与组元浓度的普遍关系是双曲线，只有在某些特殊情况下，两组元的溅射率相差不大时，可以近似看成线性关系。

Testing results showed that in a sputtering cycle the sputtering time for Cu/Ga target has greatest effect on the final element distributi

实验中发现，在一个溅射周期中，Cu/Ga合金靶溅射时间对最后成分影响最大，其次是In靶溅射时间，非溅射时间的长短对成分也有影响。

In chapter 2, we systematically introduced the theory and process of radio frequency magnetron sputtering and ion beam deposition sputtering.

Finally, we hold that there were a large number of ions in the sputtering space, which would be bounded by Lorentz force and gradient magnetic field force and their interactive forces, thus resulting in the generation of the spots and loops.

Results showed that the kinetics of photocatalytic degradation of ethylene by TiO2/ACF desoposited Pt in the simulated cold storage environment for horticultural products could be described using the pseudo first-order equation. The prepared TiO2/ACF-Pt, in the process of which Pt was initially deposited on the surface of ACF and then TiO2 was coated, would promote the activity of ethylene decomposing. When ion sputtering time was 60 seconds (Pt/Ti atomic concentration ratio was 0.112), the apparent rate constant of the reaction of TiO2/ACF-Pt was 1.16 times as much as that of TiO2/ACF. The micrographic structure of ACF was not damaged and an excessive porous structure, which was contributive to absorbing the diluted ethylene, was obtained by the way of ion sputtering Pt.

结果表明：在模拟园艺产品冷藏环境中，TiO2 /ACF-Pt光催化降解乙烯的动力学可用表观一级速率方程来描述；ACF表面先溅射沉积Pt，再进行TiO2附着方案，能提高降解乙烯的能力，当溅射时间为60 s（Pt/Ti原子浓度比为0.112）时，表观一级速率常数是未溅射Pt的1.16倍；TiO2/ACF-Pt的制备方法，对ACF形貌结构没有破坏，并能得到有利于对微量乙烯的吸附的多孔结构。

The contamination of the different target, the oxidation and the carbonization during the sputtering process and the crystal structure of Pd all have the significant influence in the performance of the rare earth films.

研究结果表明，衬底温度为150℃，Ar~+的溅射气压为4.5×10~(-1)Pa时比较适宜；溅射过程中，不同溅射靶之间的相互污染、氧化、碳化以及Pd保护层结晶性能的好坏等都对稀土薄膜的性能有很大影响。

There are two vacuum plating methods. One is CVD. The other is PVD. PVD includes evaporation plating (arc, electronic gun and resistance wire) and sputtering plating (DC magnetron Mid-frequency and RF).
